The linter and formatter for agentic development
Agents write most of the code now. Ultracite is the linter and formatter for agentic development, a zero-config preset for Oxlint, Biome, and ESLint that keeps agent-written code consistent and type-safe. Ultracite checks every edit agents make against hundreds of strict rules in under half a second, so what reaches review is consistent, type-safe code instead of slop. Used by engineering teams at OpenAI, Vercel, Mintlify, and thousands of open source projects: ultracite.ai
