Ultracite

Apply consistent linting and formatting rules to agent-written code

Meet Ultracite

Ultracite provides linting and formatting presets for JavaScript and TypeScript projects, with integrations for AI coding workflows. Developers choose an engine such as Oxlint, Biome, or ESLint, then initialize project configuration and rules covering types, React hooks, accessibility, asynchronous code, and correctness.

Agent hooks can run checks after file edits, apply automatic fixes, and return unresolved diagnostics to the assistant. Setup also connects editors and Git hooks so that the same expectations follow code through development. Rules remain configurable for each project. Ultracite is useful for teams that want generated and manually written code to pass a consistent set of checks before review.
