Show HN: LangSpend – Track LLM costs by feature and customer (OpenAI/Anthropic) https://bit.ly/3X2MMFw

Show HN: LangSpend – Track LLM costs by feature and customer (OpenAI/Anthropic) We're two developers who got hit twice by LLM cost problems and built LangSpend to fix it. First: We couldn't figure out which features in our SaaS were expensive to run or which customers were costing us the most. Made it impossible to price properly or spot runaway costs. Second: We burned 80% of our $1,000 AWS credits on Claude 4 (AWS Bedrock) in just 2 months while building prototypes of our idea but we had zero visibility into which experiments were eating the budget. So we built LangSpend — a simple SDK that wraps your LLM calls and tracks costs per customer and per feature. How it works: - Wrap your LLM calls and tag them with customer/feature metadata. - Dashboard shows you who's costing what in real-time - Currently supports Node.js and Python SDKs Still early days but solving our problem. Try it out and let me know if it helps you too. - https://bit.ly/47jJNid - Docs: https://bit.ly/3LcnulX - Discord: https://bit.ly/3X15QnI https://bit.ly/3X2cCtl October 30, 2025 at 11:40PM

Show HN: Emotive Engine – Animation engine with musical time (not milliseconds) https://bit.ly/4qyMpA4

Show HN: Emotive Engine – Animation engine with musical time (not milliseconds) Hey HN! I'm the creator of Emotive Engine. I've been working on this for 2+ years and finally open-sourced it today. The core idea: Most animation libraries work in milliseconds. Music works in beats. This creates a mismatch - hardcode a bounce for 500ms (perfect at 120 BPM), switch to 90 BPM, and everything drifts because 500ms is now 0.75 beats. Emotive Engine uses musical time as the atomic unit. Specify animations in beats, and they automatically become: - 500ms at 120 BPM - 667ms at 90 BPM - 353ms at 170 BPM Change tempo, everything adjusts. No recalculation needed. Built for AI interfaces (chatbots, voice assistants) but works for any real-time character animation. Pure Canvas 2D, 60 FPS on mobile, 2,532 tests passing. Live demo at https://bit.ly/4qDnxHK - the hero banner on GitHub was generated with the engine itself. Happy to answer any technical questions!

Show HN: HortusFox – FOSS system for houseplants with enterprise-scale features https://bit.ly/4oC3NCk

Show HN: HortusFox – FOSS system for houseplants with enterprise-scale features HortusFox is a free and open-source management, tracking and journaling system for indoor and outdoor plants. It's 100% FOSS software under the MIT license, but still has grown to a scale that can be considered enterprise-scale. That was possible because of the great community that evolved around this leafy project, that kept me motivated as well as supported me in a very kind and lovely way. After a few months of no new version release, a few days ago I've published v5.3 of HortusFox, which provides some cool changes to help empower your plant parenting. You can see a very detailed changelog in the 5.3 release page on GitHub. Overall 25 issues have been resolved, where some of them were actually quite big. If you're new to HortusFox: the system offers you a large number of features to support your plant parenting (or gardening) journey with plant details, locations, photos, default and custom plant attributes, inventory system, tasks system, calendar, history (to keep a memory of your leafy friends), collaborative group chat and a few opt-in features such as weather forecast or plant identification (via photo). It also offers an extensive REST API, backup feature and themes (if you want your workspace a little more personal). I have to say, for me it's the perfect blend of two things: The passion for software development as well as the fondness for nature. I'm really grateful for that. Thanks for reading and have a wonderful and leafy day. https://bit.ly/3JxfRFY October 29, 2025 at 02:22AM

Show HN: UndatasIO's document parser MCP server is online https://bit.ly/3Jj6ObR

Show HN: UndatasIO's document parser MCP server is online Hey HN, Alex here, founder of undatas.io. Since we launched our core document parsing API, we've had fantastic feedback from developers who love the precision and the "pay-on-accept" model. But as we watched people build more complex systems, we noticed a common pattern: everyone was writing the same boilerplate code to manage their workflows. Developers were building their own logic to handle workspaces, manage batches of files within tasks, poll for results, and handle state. Our raw API is powerful for single transactions, but it left the orchestration part up to you. To solve this, we've built and are now launching our MCP (Multi-Channel Platform) server. Think of it as a stateful, command-based orchestration layer that sits on top of our core parsing API. Instead of you having to write code to manage IDs and track the status of multi-file jobs, the MCP server handles it for you through a simple, logical interface. The workflow is structured around a clear hierarchy: Workspace -> Task -> File. You can use straightforward commands like: - UnDatasIO_get_workspaces to get your work_id. - UnDatasIO_upload to add files to a specific task_id. - UnDatasIO_parse to kick off parsing for a list of file_ids. - UnDatasIO_get_parse_result to poll for the job status without building your own loop. This is perfect for anyone building complex, multi-file data processing pipelines, integrating with low-code platforms, or who simply wants to manage large batch jobs without the hassle of writing and maintaining state-management code. Our goal is to let you focus on what to do with the data, not the plumbing required to get it. We believe this will make building robust document workflows much faster and more reliable. We're just getting started and are eager for your feedback. We've put together a comprehensive guide and a video tutorial to walk you through it. MCP User Guide (Full API Reference): https://bit.ly/3JwliFg Video Tutorial on YouTube: https://www.youtube.com/watch?v=_xobbKiPyf4 Our Official Website: https://bit.ly/4oH5gaA I'll be here all day to answer any questions.

Show HN: Easily visualize torch, Jax, tf, NumPy, etc. tensors https://bit.ly/3L6JezD

Show HN: Easily visualize torch, Jax, tf, NumPy, etc. tensors hey hn, wrote a python library for myself to visualize tensors. Makes learning and debugging deep learning code so much easier. Works seamlessly with colab/jupyter notebooks, and other python contexts. It's built on top of the graphics backend, chalk ( https://bit.ly/42XIAKW ). why? Understanding deep learning code is hard—especially when it's foreign, because it's hard to imagine tensor manipulations, e.g. `F.conv2d(x.unsqueeze(1), w.transpose(-1, -2)).squeeze().view(B, L, -1)` in your head. Printing shapes and tensor values only get me so far. tensordiagram lets me quickly diagram tensors. Other python libraries for creating tensor diagrams are either too physics and math focused, not notebook-friendly, limited to visualizing single tensors, and/or serve a wider purpose (so have a steep learning curve). https://bit.ly/3L8oSpD October 27, 2025 at 10:30PM

Show HN: Helium Browser for Android with extensions support, based on Vanadium https://bit.ly/47cCclm

Show HN: Helium Browser for Android with extensions support, based on Vanadium Been working on an experimental Chromium-based browser that brings 2 major features to your phone/tablet: 1. desktop-style extensions: natively install any extensions (like uBO) from the chrome web store, just toggle "desktop site" in the menu first. 2. privacy/security hardening: applies the full patch sets from Vanadium (with Helium's currently wip). Means you get both browsers' excellent privacy features, like Vanadium's webrtc IP policy option that protects your real IP by default, and security improvements such as JIT being disabled by default, all while being a reasonably efficient FOSS app that can be installed on any (modern) android. It's still in beta, and as I note in the README, it's not a replacement for the full OS-level security model you'd get from running the GrapheneOS Vanadium combo. However, goal was to combine privacy of Vanadium with the power of desktop extensions and Helium features, and make it accessible to a wider audience. (Passkeys from Bitwarden Mobile should also work straight away once merged in the list of FIDO2 privileged browsers) Build scripts are in the repo if you want to compile it yourself. You can find pre-built releases there too. Would love any feedback/support! https://bit.ly/4hqrCuu October 26, 2025 at 11:41PM

Show HN: Postnix AI – Helps Indie Hackers Get Their Work Seen Hi HN , Six months ago, I built JustGrind, an AI habit coach. Coding it was fun; shipping it? Nightmare. Marketing it? Even worse. I realized the hardest part of building a product isn’t the coding—it’s getting people to actually see it. So I built Postnix AI, a tool that helps indie hackers, creators, and solo founders craft posts that get attention: - Fetches top-performing posts in your target communities - Analyzes what makes them work - Helps you write your own posts that feel natural and hit the right vibe - Suggests flairs, formatting, and style tweaks that increase visibility and engagement Key lesson: no matter how good your product is, if nobody knows it exists, it doesn’t matter. It’s still early days, but people are already getting traction with their posts. Would love feedback from the HN community!

Show HN: I'm rewriting a web server written in Rust for speed and ease of use Hello! I got quite some feedback on a web server I'm building, so I'm rewriting the server to be faster and easier to use. I (and maybe some other contributors?) have optimized the web server performance, especially for static file serving and reverse proxying (the last use case I optimized for very recently). I also picked a different configuration format and specification, what I believe is easier to write. Automatic TLS is also enabled by default out of the box, you don't need to even enable it manually, like it was in the original server I was building. Yesterday, I released the first release candidate of my web server's rewrite. I'm so excited for this.

Show HN: Hokusai Pocket (WIP) – Portable GUIs with MRuby Whassup?, A couple years ago, I started a project for easily authoring GUIs with Ruby. The project is named Hokusai. It features the ability to compose reactive UI components with events and props, and uses a unique-ish template language. More information on Hokusai can be found here: https://bit.ly/452xMg9 Since then I've worked on Hokusai Native ( https://bit.ly/42QznE5 ), which compiles a GraalVM native image / TruffleRuby version of Hokusai that can run / interpret these lil' gui apps. It's quite bloated though, as it has to ship all of truffle ruby + native image and supporting libs. Recently, I applied for a grant to develop a more portable version of this library using MRuby, and got pretty far while waiting for the results. It is named Hokusai Pocket and I consider it to be the final form/approach of this project. I wrote a builder in crystal-lang that embeds the entire Hokusai ruby code as MRuby bytecode, as well as the supporting C code. It can scaffold new projects by building tree-sitter/mruby/raylib, and outputs a binary from a source ruby file. It produce pretty small binaries (~3mb for MacOS) and uses raylib as the rendering engine. For an gif and example of a Hokusai Pocket demo please direct your mouse clicks to this gist: https://bit.ly/4hmyzgj... I'd love to hear how this project plays for people.

Show HN: WP-Easy, framework to build WordPress themes The inspiration for this framework came from my brother, an amazing graphic designer who wanted to build WordPress themes using only his FTP-based code editor. He knows HTML and CSS really well, and some jQuery, but not modern JavaScript.

WP-Easy lets people like my brother build professional, modern themes without the usual barriers, just code with your favorite editor and see the results instantly. Key features: 1.

Show HN: OneClickPRD – Save hours vibe coding with concise PRDs https://bit.ly/4hhGr2j

Show HN: OneClickPRD – Save hours vibe coding with concise PRDs Hi HN, I built OneClickPRD because as a solo builder I often wasted hours vibe coding without clear goals. I’d start with an idea, but it was vague, so the code got messy and I had to redo things. OneClickPRD asks you a few questions about your product and then generates a short, structured PRD. The format works well with AI tools like Replit, Lovable, or v0, so you can go from idea to working MVP much faster. Demo: https://bit.ly/4hg9HGN Would love your feedback: does this feel useful for your projects, and what would make it better? https://bit.ly/4hg9HGN October 17, 2025 at 10:25PM

Show HN: Code review for AI native teams https://bit.ly/470DxvG

Show HN: Code review for AI native teams Bottleneck is a desktop app for code reviewing AI-written pull requests. The goal is to be able to track PRs on GitHub authored by agents (i.e. Codex, Devin, Cursor, Claude Code) and compare branches. So if you throw multiple coding agents at a ticket, this would be an easier way to let agents "bake off" against each other and pick the best one. (No need to open the Github website and switch between slow loading tabs). I'd love feedback from any power users who are deep with AI coding agents. https://bit.ly/4ooJwA1 October 18, 2025 at 01:22AM

Show HN: Simulation of the Tech Industry in 2027 https://bit.ly/3KQ5iyk

Show HN: Simulation of the Tech Industry in 2027 Hi HN, this is Miguel, and I built a simulation of what the tech industry will look like in 2027. We hear a lot about job loss, AI literacy, and in general the fear of the future... and I wanted to capture these feelings through an immersive experience. Check it out here: https://bit.ly/3KKBMtQ Sam Altman says that there will be mass layoffs, but many “new jobs” will be created, and when asked they say “AI literacy”... but no one has a clear picture of what this would actually look like? I saw a recent government article titled "AMERICA’S TALENT STRATEGY: BUILDING THE WORKFORCE FOR THE GOLDEN AGE" written by the U.S. Department of Labor, and I wanted to explore what it could look like when the government intervenes in this bleak future. It discusses “work-based learning models” in partnership with corporations, government-assisted “Registered Apprenticeships” for upskilling, not sending people to college again, etc. The simulation was built from scratch using React, JS, CSS, and HTML. I hope this project gives a feeling of reflection, motivation for growth, and empowerment. https://bit.ly/4n9xTw2 October 16, 2025 at 02:23AM

Show HN: Ark v0.6.0 – Go ECS with new declarative event system https://bit.ly/4n003t1

Show HN: Ark v0.6.0 – Go ECS with new declarative event system Ark is a high-performance Entity Component System (ECS) library for Go. Ark v0.6.0 introduces a new event system built around lightweight, composable observers. These allow applications to react to ECS lifecycle changes like entity creation/removal, component updates, relation changes using declarative filters and callbacks. Observers follow the same patterns as Ark’s query system, making them easy to integrate and reason about. Custom events are also supported. They can be emitted manually and observed with the same filtering logic, making them ideal for modeling domain-specific interactions such as input handling, and other reactive game logic. As a new performance-related feature, filters and queries are now concurrency-safe and can be executed in parallel. This release also includes a load of performance improvements, from faster archetype switching over optimized query and table creation to improved performance of bitmask operations. The new World.Shrink method helps reclaim unused memory in dynamic workloads. Docs have been expanded with a full guide to the event system, examples for both built-in and custom events, and an Ebiten integration example. A cheat sheet for common operations has been added. Finally, Ark now has 100% test coverage. Changelog: https://bit.ly/47lnnNk Repo: https://bit.ly/4nnttC3 Would love feedback from anyone building games, simulations, or ECS tooling in Go. https://bit.ly/4nnttC3 October 14, 2025 at 08:04AM

So I built SeekLex — it preprocesses over 1M aftermarket domains to filter out nonsense, detect meaningful words, and generate creative domain hacks when your preferred names are taken. The goal is to make domain discovery smarter and faster, using automation and (soon) AI. I’m planning to add an API, MCP integration, and an LLM agent to help you find the best domain for your next project.

Show HN: Rebuilt Bible search app to run 100% client-side with Transformers.js https://bit.ly/4747QjJ

Show HN: Rebuilt Bible search app to run 100% client-side with Transformers.js I rebuilt Biblos, my semantic Bible search app, to run entirely in your browser. No more server costs. The main challenge was fitting an accurate text embedding model into browsers. Last year's version cost $20 monthly to host. The new version runs free on Vercel and searches 31k Bible verses without sending data to any server. I pre-compute embeddings for all 31,000 Bible verses offline using BGE-large-en-v1.5. Each verse becomes a 1024-dimensional vector stored as JSON, compressed into ZIP files by book. When you visit the site, your browser downloads Transformers.js and the BGE model. The model generates an embedding for your query, then finds similar verses using cosine similarity against the cached embeddings. Everything happens in your browser. The app is designed to search Bible verses by semantic meaning, not just keywords. There's a separate tab to read daily passages with church fathers commentary from 15+ sources, based on a read the bible in a year plan. Free to use, no sign-in features or anything like that. Try it out biblos.app. I'd appreciate feedback on the search experience, especially on mobile devices! Happy to discuss the technical details or help anyone building similar browser-based ML applications. https://bit.ly/4nKryYL October 10, 2025 at 10:20PM

Show HN: CrossPromote – Your own ad network https://bit.ly/4mZKRfF

Show HN: CrossPromote – Your own ad network Hi HN! While working on my side projects, I realized something - I have all these apps, but there is no easy way to cross-advertise them. Putting my own ads in my own apps is way easier and cheaper than paying Google or Facebook to do that. Moreover, there is a chance for higher returns if my ads are in the same niche as the app. At first, I made a basic implementation for myself, but I wanted something more - the number of views, clicks, platform-specific redirects (e.g. Google Play for Android and App Store for iOS), changing links dynamically, etc. That’s why I made CrossPromote Picture this: you have a travel tracker, so why not put an affiliate link to a service that offers global eSIM services? Or a multi-currency account? Travel insurance? Your other app that is a travel guide? The possibilities are endless, just like returns. CrossPromote is a simple tool for app and site owners to drop in custom ads, affiliate links, or cross-promos. Perfect for anyone who has an app or a website in some niche. The first version is done and ready to use. It’s a 100% solo project and I'm trying to find a product-market fit while gathering feedback that can help me grow it into a better service. Let me know what you think! https://bit.ly/43eYwIz October 10, 2025 at 05:10AM

Show HN: Oh Yah – Routine management app I built for my sons Hi HN! I built Oh Yah! to help my sons (age 7 and 10) stick to daily routines without constant reminders. The core idea: minimal distractions during tasks by locking navigation when a timer is running, plus optional photo-based task completion for accountability Built with React Native/Expo and Firebase. The trickiest part was designing the UX to be simple enough for kids with minimal distractions while giving parents enough control – ended up with a task-definition system that lets parents create weekly schedules with daily toggles instead of duplicating tasks across days It's on the App Store now after a few months of dogfooding with my family.

I cloned the OpenAI Codex repo (the open-source AI coding assistant that recently trended on HN) — but it was in Rust. So, I used an Cursor to help me extract and translate 18+ agentic patterns from Codex’s codebase into Python. That small experiment turned into a full open-source guide: GitHub: Codex Agentic Patterns https://bit.ly/46YwbaM Each pattern comes with: A short explanation and code sample A runnable exercise and agent snippet A summary of how Codex used the pattern (e.g., prompt chaining, tool orchestration, reflection loops, sandbox escalation) One full working Python agent that ties it all together If you’ve read the agentic design patterns book or explored Codex, this is a bridge between theory and practice — focused on runnable, open examples instead of abstract diagrams. It’s completely free and open-source. Would love feedback, ideas, or even new patterns from your own agent experiments. https://bit.ly/48OR0ry October 7, 2025 at 11:41PM

Show HN: World Amazing Framework: Like Django for Civilization https://bit.ly/42rIrPw

Show HN: World Amazing Framework: Like Django for Civilization Any initial thoughts? This framework is meant to be a tool for construction, so if you want to play around with it for creating potential specific implementations, you can drop the contents of the website, the GitHub README, and the entire overview.md into an AI chat, and that should be enough to use the framework, at least conceptually. Would y'all want me to pre-prime a chat in Google AI Studio with the full context of the plan and some basic direction for discourse? I can share a link to a ready-to-go environment. The core documentation should answer most mechanical questions. And if you feed the docs into an AI chat, you can ask it any question you may have, or to simply ask it to explain something in different ways, or hypothesize solutions to any world issue, either systemic or regional. Gemini Pro 2.5 can take the full doc in one prompt, and its ability to co-create ideas is remarkable. I've been using it mostly through the AI Studio interface. Much of the overview is as much my work as it is a synthesis of my collaboration with Gemini Pro 2.5, ChatGPT-4o, and some early contributions from GPT-4 about a year ago. Before LLMs, I was building out pamphlet-style pages on a website (that are up at whomanatee.org, which is the base wrapper implementation of the framework), and I was planning to use them as talking points. I was anticipating that much of the deep thinking would have to happen in slow, public discourse. With LLMs, I've been able to stress-test these ideas from every possible angle, using any past event or theory to see if the framework could withstand scrutiny. At one point, a model argued that Adam Smith would have rejected this idea as fantasy. So I worked with it to develop an economic plan that "synthetic Adam" praised. It's incredible that we now have the ability to get synthesized thoughts from almost any perspective. You could ask it, "What would Barack Obama think of this plan? And using the framework, what would be your response to any hesitations he may have?" And it responds with incredible analysis, synthesis, and feedback. https://bit.ly/3VLR8Au October 4, 2025 at 11:14PM

Show HN: Neural Emotion Matrix for NPCs https://bit.ly/4n7FUlb

Show HN: Neural Emotion Matrix for NPCs Hey! I built this system to humanize NPCs by giving them emotions using Rust and ML. The system provides emotion coordinates (based on Russell's circumplex model) from text input or actions, with persistent emotional memory per entity. Think NPCs that remember how they feel about specific players or events. I pre-trained a DistilBERT model on ~1k video game dialogues (Skyrim, Cyberpunk, etc.) and plan to extract and evaluate 100k+ dialogues soon. However studio/team can manually add dialogues to enrich their own dataset. The matrix doesn't generate dialogue, it only analyzes content. When you pass text or an action, it returns emotion coordinates on the valence (pleasant/unpleasant) and arousal(energetic/calm) scale. For example: - [0.00, 0.00] = neutral - [0.29, 0.80] = excited - [-0.50, -0.30] = sad/tired I made a quick visualizer here to help understand https://bit.ly/3WnQZmU The system helps select which dialogue/action to play based on emotional state: - Player says something bad to NPC → system detects negative valence → game picks from "angry dialogue pool" - NPC remembers past positive interactions → system returns positive valence → friendlier responses available So, the devs still write the dialogues or choose the next actions, but the matrix helps manage NPC emotional states and memory dynamically. Here's the project structure to better understand how it works: - src/config: Helper utilities for NPC configuration setup - src/module: The core engine with emotion prediction, memory storage, and entity management - src/api: FFI layer with pub extern "C" to bridge our modules with C/C++ game engines and modding tools (Unity, Unreal, etc.) To implement it, just call `build.sh`, it will create DLL files that you can use to call the matrix functions directly in C++/C/C#. I'd love feedback on code quality and overall architecture. Feel free to be honest about the good, the bad, and the ugly. PRs welcome if you want to contribute! https://bit.ly/48OIRmR September 29, 2025 at 02:05PM

I fly the same route every month, and there’s no platform that knows my preferences so that I can open it, find and book my flight, and close it within a minute. - Booking is slow. I hate seeing a long clunky airline form each time I need to book. I want booking a flight to feel more like booking an Uber. How it works: 1. Optionally make an account and save your traveler preferences. Personally, I've specified my routine route as SFO to CLE and that I only want red-eye direct flights for this route. 2. Search for flights using chat or the search panel. Chat feels especially time-saving when you have preferences saved (e.g. I just say “search my routine trip"). 3. Once you find the flight you want, use the one-click book feature which books your flight directly with the airline. The first time you book a flight, you’ll have to fill out your traveler info, but you won't see that form after that. Notes: - Your booking is directly with the airline (this means when something goes wrong, you get direct support from the airline—not a third-party) - You can add your rewards numbers for each airline to keep earning points/status The ultimate goal is to create the best possible experience that every traveler wants, but that OTAs and airlines don’t care to create. Also very receptive to hearing pain points from frequent flyers; we think this space is really outdated and could use some innovation.

Show HN: ChartDB Agent – Cursor for DB schema design https://bit.ly/3VGI9R5

Show HN: ChartDB Agent – Cursor for DB schema design Last year we launched ChartDB OSS ( https://bit.ly/3JjJ4UG ) - an open-source tool that generates ER diagrams from your database (via query/sql/dbml) without needing direct DB access. Now we’re launching the ChartDB Agent. It helps you design databases from scratch or make schema changes with natural language. You can: - Generate schemas by simply describing them in plain English - Brainstorm new tables, columns, and relationships with AI - Iterate visually in a diagram (ERD) - Deterministically export SQL script Try it out here - https://bit.ly/3Kx7Z7C - no signup required. Or sign up and use it on your own database Would love to get your feedback :) https://bit.ly/48I7XDW October 1, 2025 at 02:38PM
