Oxlint

Oxlint is a Rust-based JavaScript/TypeScript linter that's 50-100x faster than ESLint. On a large codebase, that's the difference between linting in 200ms versus 20 seconds. It covers the most commonly used rules and the performance improvement transforms linting from a CI bottleneck to an instant feedback loop.

We've replaced ESLint with Oxlint on all active projects. The migration was straightforward — most projects only use a handful of ESLint rules that Oxlint supports natively. The speed improvement alone justifies the switch.
