[Other] Show HN: Muxide – Zero-dep pure Rust MP4 muxer (H.264/H.265/AV1, no FFmpeg)

[Other] Show HN: MDXport – Browser-Based Markdown to PDF Using Typst and WASM Hi HN,<p>I built this because I was frustrated with existing Markdown-to-PDF converters. Most of them rely on HTML&#x2F;CSS (puppeteer) which often messes up pagination and tables, or they require uploading data to a server (privacy concerns).<p>MDXport is a purely client-side tool.<p>The Stack: - Core: Typst (a modern LaTeX alternative) compiled to WebAssembly. - Privacy: Zero data leaves your browser. All rendering happens locally via WASM. - Feature: It handles page breaks and complex tables much better than standard CSS print drivers.<p>I also added some heuristics to automatically fix common formatting errors from LLM generated markdown (e.g., broken nested lists or overflowing tables).<p>It&#x27;s currently an MVP. No sign-up required, free to use.<p>I&#x27;d love to hear your feedback on the rendering quality compared to Pandoc&#x2F;LaTeX.<p>Link: <a href="https:&#x2F;&#x2F;www.mdxport.com" rel="nofollow">https:&#x2F;&#x2F;www.mdxport.com</a>

[Other] Show HN: Minimal DL library in C – 24 NAIVE CUDA/CPU ops, autodiff, Python API

[Code Quality] Show HN: High-Performance Wavelet Matrix for Python, Implemented in Rust I built a Rust-powered Wavelet Matrix library for Python.<p>There were surprisingly few practical Wavelet Matrix implementations available for Python, so I implemented one with a focus on performance, usability, and typed APIs. It supports fast rank&#x2F;select, top-k, quantile, range queries, and even dynamic updates.<p>Feedback welcome!

[Other] Show HN: GitForms – Zero-cost contact forms using GitHub Issues as database got tired of paying $29–99&#x2F;month for simple contact forms on landing pages and side projects (Typeform, Tally, etc.).So I built GitForms: an open-source contact form that stores submissions as GitHub Issues.How it works:Form runs on your Next.js 14 site (Tailwind + TypeScript) On submit → creates a new Issue in your repo via GitHub API You get instant email notifications from GitHub (free)<p>Zero ongoing costs:No database, no backend servers Deploy on Vercel&#x2F;Netlify free tier in minutes Configurable via JSON (themes, text, multi-language)<p>Perfect for MVPs, landing pages, portfolios, or any low-volume use case.Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;Luigigreco&#x2F;gitforms" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Luigigreco&#x2F;gitforms</a> License: CC-BY-NC-SA-4.0 (non-commercial only – fine for personal projects, not client work).Curious what HN thinks: would you use this? Any obvious improvements or edge cases I missed?Thanks!

[Database] Show HN: Tonbo – an embedded database for serverless and edge runtimes

[API/SDK] Web3 wallet tools NexaPay provides client-side Web3 wallet tools. Generate and manage wallets locally with 100% non-custodial control.

[Testing] Open source testing and reporting platform QA Studio: Open-source test management platform with automated test reporting, test case management, and Playwright integration. Zero code changes - automatically discovers your tests. Built by QA engineers for modern CI/CD pipelines.

[Other] The open-source, local-first alternative to Kombai. OpenKombai is a free, open‑source, privacy‑first “design to code” tool that converts UI screenshots and designs into production‑ready React + Tailwind CSS using local LLMs via Ollama. It runs fully on your machine (no API keys, cloud, or token costs), ships with a drag‑and‑drop Studio UI, and is built with a FastAPI backend plus a modern React/Vite/Shadcn frontend for easy hacking, extension, and self‑hosting.

[Other] FastAPI Endpoints: Efortless routing, simplified fastapi-endpoints is a lightweight and simple file-based router for FastAPI framework. The key features are: - Simple: Organize and define routes directly through a clear and simple file structure. - Auto Discovery: Automatically detects and registers all defined routers. - Effortless Integration: Seamlessly integrates with existing FastAPI projects. - Selective Routing: Include or exclude specific routers by specifying Python modules.

[Other] Monitor and manage Github Copilot usage With one simple view, you can see requests, costs, model breakdowns and usage trends over time – so you can decide if Copilot is paying off. I built this after asking myself “Am I actually using GitHub Copilot enough to justify the cost?” The existing GitHub dashboards weren’t enough, so I created Copilot Tracker to give a clear, focused view on usage and value. Check out the landing page to try a quick dashboard interactive demo

[Other] Shared and synchronized AI memory + reasoning across teams Most AI coding tools are single-player. Your AI forgets everything when the session ends, forcing every dev to waste time on redundant exploration. Grov turns your AI coding agent into a collective team brain. It captures the reasoning behind every solution and syncs it to your entire team. If one dev’s AI figures out your auth system, everyone’s AI knows it instantly. Currently works with claude code, expansion: codex, gemini Later: cursor
