SparrowBase is the $0-to-start, open-source backend platform on Cloudflare Edge. Auth, Database, Storage, AI Vector Search, and Rate Limiting — all pre-wired for Cursor, Windsurf, v0, and Claude.
SparrowBase gives Cursor, Windsurf, v0, Lovable, Bolt, and Claude a pre-wired Cloudflare Edge backend with Auth, Database, Storage, AI Search, and Rate Limiting — so they generate production-grade code on the first try , not hallucinated Express.js that crashes at deploy. No server configuration. No database setup. No $25/mo hosting fees. Type what you want to build in plain English, copy the generated master prompt, and paste it into Cursor, Claude, or Lovable. 1️⃣ 1. Describe your idea Click "Copy Master Prompt" above 2️⃣ 2. Paste into Cursor or Claude AI builds your database, auth & UI 3️⃣ 3. Live on Cloudflare for $0/mo No servers to manage, ever ⚡ Platform Features Everything you need…from sparrowbase.pages.dev

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
