Show HN: I created a beautiful number animation library for React Native Hi! I've been frustrated with the fact that the beautiful NumberFlow library for web (link) is not available on React Native - a platform that I think is much more animation native than the web is. And there are no alternatives of the same quality available. So I reimplemented it myself, basically from the ground up. Introducing Number Flow React Native. I am aiming for this to be the best number animation library for React Native. - Beautiful animation easing directly inspired by web NumberFlow - Supporting both Native and Skia versions - Full i18n support for locales, things like compact or scientific notations, etc. - TimeFlow component for timers and counters - Custom digit bounding for things like binary - Supporting 37 different numeral systems such as Arabic, Thai, and many others - A dedicated, shared worklet mode for as much FPS as possible perfect for sliders or gestures for example - Built on top of React Native Reanimated v3+ - Also supports web via Expo Web Please check out the docs: https://ift.tt/kEhQpAG And star it on GitHub if you like it: https://ift.tt/DMhbTiK Let me know what you think! https://ift.tt/TtZs7J1 February 20, 2026 at 10:16PM

Show HN: Codedocent – Code visualization for non-programmers https://ift.tt/aKVU9lg

Show HN: Codedocent – Code visualization for non-programmers I'm a hardware engineer who reads schematics, not source code. I kept needing to understand codebases for projects I was managing but couldn't read the syntax. So I built a tool that turns any codebase into an interactive visual map with plain English explanations. Point it at a folder, get nested colored blocks showing the structure (directories → files → classes → functions). Click to drill down. AI generates summaries written for humans, not programmers. Architecture mode shows a dependency graph so you can see how modules connect. Built the whole thing in ~30 hours using a multi-node AI workflow: Claude for planning/decisions, Claude Code for implementation, five other models for adversarial security review (42 fixes across 6 rounds). I made every design decision; AI wrote every line of code. Cloud AI (OpenAI/Groq) or local AI (Ollama) — your choice. pip install codedocent and run the setup wizard. MIT licensed. Would love feedback from people who actually write code — does this help when onboarding onto unfamiliar codebases? https://ift.tt/rpEHqW2 February 20, 2026 at 12:21AM

Show HN: A physically-based GPU ray tracer written in Julia https://ift.tt/ML4H6jO

Show HN: A physically-based GPU ray tracer written in Julia We ported pbrt-v4 to Julia and built it into a Makie backend. Any Makie plot can now be rendered with physically-based path tracing. Julia compiles user-defined physics directly into GPU kernels, so anyone can extend the ray tracer with new materials and media - a black hole with gravitational lensing is ~200 lines of Julia. Runs on AMD, NVIDIA, and CPU via KernelAbstractions.jl, with Metal coming soon. Demo scenes: github.com/SimonDanisch/RayDemo https://ift.tt/eBFyWdJ February 19, 2026 at 07:55AM

Show HN: Potatometer – Check how visible your website is to AI search (GEO) Most SEO tools only check for Google. But a growing chunk of search is now happening inside ChatGPT, Perplexity, and other AI engines, and the signals they use to surface content are different. Potatometer runs multiple checks across both traditional SEO and GEO (Generative Engine Optimization) factors and gives you a score with specific recommendations. Free, no login needed. Curious if others have been thinking about this problem and what signals you think matter most for AI visibility. https://ift.tt/fXbLDH1 February 19, 2026 at 03:41AM
