Show HN: Baby's First International Landline https://bit.ly/42Drd1F

Show HN: Baby's First International Landline Hi HN, As a weekend project, I hacked together a physical phone, a Raspberry Pi running Asterisk and Twilio, to let toddlers safely make international calls. I’ve documented the setup in this write-up and published the code + Ansible playbooks on GitHub so others can replicate it. I built this so kids of expats can easily stay in touch with family on other continents. Would love feedback from anyone who’s worked on something similar or tries building this themselves! writeup: https://bit.ly/4n3tpqD... github repos: - https://bit.ly/3W2l0J6 - https://bit.ly/46MfW1A https://bit.ly/3WxYOqf October 8, 2025 at 02:31PM

Show HN: Seeklex – Better domain search with automation https://bit.ly/3J2BJsA

Show HN: Seeklex – Better domain search with automation I often look for domains when brainstorming new projects, but most domain marketplaces are full of gibberish names or already-taken domains. 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. Would love your feedback and ideas. https://bit.ly/48s1dtP October 12, 2025 at 11:19PM

Show HN: Radiopuppy.com – Minimal Web App for Listening to Online Radio https://bit.ly/4mTTubr

Show HN: Radiopuppy.com – Minimal Web App for Listening to Online Radio I listen to online radio all the time while working, but none of the web based apps I found fit my needs. So I built RadioPuppy.com - https://bit.ly/4qbZNdy It’s a lightweight web app that lets you quickly search thousands of online streaming radio stations and save your favourites. I’m using the excellent https://bit.ly/471tuVJ API as the data source for stations. The tech stack is: Laravel 12, Inertia.js, React, Redis, and PostgreSQL. Future features I am thinking of... - Let users upload their own stream URLs, so if something isn’t available via the API, they can still save and listen to it. - Plot stations on a map to browse by location. - Play History: Keep track of stations you’ve listened to, Would love any constructive feedback, thanks! https://bit.ly/4qbZNdy October 12, 2025 at 05:03AM

Show HN: Cjam – a modern MP3 file editor Cjam is an MP3 editing and playback tool for Windows. The MP3 format itself has been stable for decades, but advances in CPU power and memory have shifted the relationship between files and hardware, creating room for new approaches to working with MP3s. Cjam provides both a GUI and scripting interface that allow you to process large numbers of files at the frame level. This improves on existing tools, offering faster and more flexible editing and playback. https://bit.ly/4nKyxRt October 7, 2025 at 12:56PM

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: Brinode – create n8n automations and AI agents from plain text https://bit.ly/434nwSO

Show HN: Brinode – create n8n automations and AI agents from plain text Hey everyone, I just launched Brinode, a tool that helps teams build automations and AI agents on top of n8n just by describing them in plain text. Instead of manually connecting nodes and debugging errors for hours, you can simply type what you want -- for example: “Scrape my website, save new data to Google Sheets, summarize it with ChatGPT, and send a custom email to my contacts.” Brinode turns that plain text into a production-ready n8n workflow in minutes. No setup, no coding, no headache. Would love to get feedback from the HN community -- especially from those who use n8n or build automations regularly. https://bit.ly/42AF6Oa October 10, 2025 at 02:59AM

Show HN: Oh Yah – Routine management app I built for my sons https://bit.ly/4qf8O5A

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. There's a 1-month free trial, then it's subscription-based. Would love feedback from other parents dealing with similar challenges https://bit.ly/47dTfU1 October 8, 2025 at 09:15AM

Show HN: Agentic Design Patterns – Python Edition, from the Codex Codebase https://bit.ly/436XYo0

Show HN: Agentic Design Patterns – Python Edition, from the Codex Codebase While reading Agentic Design Patterns by Antonio Gulli, I wanted to see how these patterns look in real code. 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
