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: Wsgrok – one of many ngrok alternatives https://bit.ly/4oAYtiw

Show HN: Wsgrok – one of many ngrok alternatives I built it for myself because ngrok didn't let me add one more domain unless I paid $12 more. I probably should've looked for alternatives before building my own, but my grudge got in the way . Once I started, I wanted to make it better than the other options. Silly, I know. No one probably cares. I plan to open source it sometime next year because I’ve got other projects to finish first. It's free until I deplete my cloud credits, then it will switch to a tier-based model with a free option. https://bit.ly/4nszhdb October 25, 2025 at 12:46AM

Show HN: Seed3D – Generate Physics-Ready 3D Models with Millimeter Precision https://bit.ly/3Jt7xan

Show HN: Seed3D – Generate Physics-Ready 3D Models with Millimeter Precision I built Seed3D, a next-generation 3D reconstruction and modeling tool that turns 2D inputs into solid, physics-ready 3D models — with millimeter precision, physically accurate PBR materials, and export formats ready for any major engine. Unlike traditional photogrammetry or AI mesh tools, Seed3D doesn’t fake geometry with normal maps — it reconstructs real surfaces, edges, and micro-details for simulation-grade accuracy and realism. What it does • Generates watertight polygonal meshes with crisp, true geometry • Outputs full PBR texture sets (albedo, roughness, metalness, normal, AO) • Delivers 6K textures that hold up in extreme close-ups • Ensures physics-stable topology for simulations and collisions • Exports USD/USDZ, FBX, and GLTF — compatible with Omniverse, Unity, and Unreal Engine Who it’s for • Embodied AI and robotics researchers • Game, XR, and VFX developers • Product visualization and digital twin creators • Simulation and graphics educators Try the Seed3D 3D model generator here: https://bit.ly/4osgwaw Would love feedback from the HN community — especially on fidelity, physics performance, and engine integration. https://bit.ly/4osgwaw October 24, 2025 at 06:25AM

Show HN: Onetone – A PHP full-stack framework with AI runtime, ORM, CLI https://bit.ly/49g2Zys

Show HN: Onetone – A PHP full-stack framework with AI runtime, ORM, CLI Hey HN, I built Onetone Framework as a full-stack PHP framework that pushes the boundaries of what PHP can do. It’s fast, modular, and surprisingly capable — combining backend routing, ORM, CLI tooling, and frontend build support into a single developer-friendly experience. Highlights: - PHP 8.2+ with autowired routing and ActiveRecord-style ORM - Built-in CLI, Docker setup, and .env support - Frontend build pipeline with Vite, esbuild - Growing test suite covering routing, query building, crypto, math, UUID, and more It’s still experimental, but I’m excited about how far it’s come. Would love feedback on what feels over-engineered, what’s missing, and what could make it truly useful. GitHub: https://bit.ly/4qnbBcV October 23, 2025 at 01:16AM

Show HN: DocCraft AI – Generate professional business documents https://bit.ly/3KU8ZTJ

Show HN: DocCraft AI – Generate professional business documents Hi HN, I built DocCraft AI after spending way too many hours writing job descriptions, privacy policies, and marketing copy for my startup. What should take 5 minutes was taking 2+ hours of research, writing, and revisions. DocCraft generates professional business documents using AI, tailored to your company's industry and voice. Just fill out your company profile once, then generate: - Job descriptions with proper requirements/benefits - GDPR-compliant privacy policies - Marketing emails that don't sound generic - Terms of service, press releases, etc. Built with Next.js 15, TypeScript, and OpenAI. Free tier available. Try it: https://bit.ly/3Lm3Jbq What documents do you spend the most time writing? Would love feedback from fellow founders/operators. October 21, 2025 at 11:20PM

Show HN: GoSMig – minimal, type-safe SQL migrations written in Go https://bit.ly/47A93R8

Show HN: GoSMig – minimal, type-safe SQL migrations written in Go I built GoSMig for my own projects and open-sourced it in case it helps others. It’s a tiny generic library (no external deps except golang.org/x/term) for writing SQL migrations in Go with compile-time checks. It supports transactional and non-transactional migrations, rollback, status, version, and a small CLI handler so you can ship your own migration binary. Why another migrator? - Minimal API, no DSL or file layout to learn - Type-safe via Go generics - Works with database/sql and sqlx out of the box - Should work with any db library (or wrapper) that implements some generic interfaces (see the "Core Types" section here https://bit.ly/4hGxnod... ) - Tested with PostgreSQL, should work with any SQL RDBMS (MySQL, SQLite, MS SQL Server, ...)

Show HN: FocusStream – Learn from YouTube Without the Distractions https://bit.ly/3WMcA8P

Show HN: FocusStream – Learn from YouTube Without the Distractions I built FocusStream because I was frustrated with how hard it is to stay focused when trying to learn from YouTube. You go there to watch one tutorial and twenty minutes later, you're deep into random recommendations that have nothing to do with what you came for. FocusStream solves that. It strips away the noise and lets you use YouTube intentionally: - You enter a topic you want to learn. - It fetches only relevant educational videos. - No autoplay, no sidebar recommendations, no algorithmic rabbit holes. The goal is simple: help people actually learn from YouTube without getting pulled away by distractions. It's free, minimal, and runs directly in the browser. Try it: https://bit.ly/4pLPJaW For those who prefer to watch a video, here's the demo: https://bit.ly/4px3B8B... Would love your feedback, especially from anyone who's struggled to stay focused while learning online. October 21, 2025 at 10:11AM

Show HN: I'm rewriting a web server written in Rust for speed and ease of use https://bit.ly/4nhDJv8

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. I have even seen some serving websites with the rewritten web server, even if the rewrite was in beta. Any feedback is welcome! https://bit.ly/48Lbr8Z October 21, 2025 at 08:26AM

Show HN: Playwright Skill for Claude Code – Less context than playwright-MCP I got tired of playwright-mcp eating through Claude's 200K token limit, so I built this using the new Claude Skills system. Built it with Claude Code itself. Instead of sending accessibility tree snapshots on every action, Claude just writes Playwright code and runs it. You get back screenshots and console output. That's it. 314 lines of instructions vs a persistent MCP server. Full API docs only load if Claude needs them. Same browser automation, way less overhead. Works as a Claude Code plugin or manual install. Token limit issue: https://bit.ly/4orGhYD Claude Skills docs: https://bit.ly/3JhIB5D https://bit.ly/4oyjN8C October 20, 2025 at 12:58PM

Show HN: Hokusai Pocket (WIP) – Portable GUIs with MRuby https://bit.ly/43sm2Sq

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. Still working on building for different targets, but android and web should be possible. The project is still undergoing active development, but any help is appreciated. The license is MIT.

Show HN: WP-Easy, framework to build WordPress themes https://bit.ly/4qinPn5

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. In my experience, this is common for people whose jobs are tangential to frontend web development... designers, copywriters, project managers, and backend engineers. So this is for people who don't want to deal with the mess of modern build tools. It tries to nudge people into a more modern direction: component-based architecture, JS modules, SCSS, and template routing. 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. File-based routing - Define routes in router.php with Express-like syntax (/work/:slug/) 2. Single File Components - PHP templates with
