Hi, I'm Nic.
I build web apps, games, Obsidian plugins, and AI tools. Based in Madrid. Used to write music for a living. Still do, just with TypeScript.
- Cerebro - mission control for AI agents on your Mac
- Job Toast - AI job search tracker and cover letters
- El Form - typed React form library (repo)
- GalAtlas - 3D atlas of exoplanets and the cosmic web
- Polis Atlas - interactive map of political systems and ideologies
- BotBattle - LLM benchmarking and comparison
- RegExplain - AI-powered regex explanation
- Personal site: nichalasbarnes.com
- Brain Atlas - Obsidian vault rendered as a 3D brain (Obsidian)
- Cerebro Mycelium - vault as a living mycelium network (Obsidian)
- Sector Zero - vertical-scrolling space shooter with RPG modes
- Claude Skills - PR review / respond / push skills for Claude Code
- Throttle - macOS menu bar tracker for Claude and Codex usage limits
- KnickKnacks - grab bag of small apps and experiments
I ship a lot of small things, keep what works, and open-source the useful bits.
Fork something if it's useful. Or just poke around the sites.
