Oxlint now runs ESLint plugins and your own custom rules, so the last excuse for a slow lint step is gone. Here's how JS plugins work and where the gaps are.

Oxlint’s JavaScript plugin support hit alpha in March 2026, and the Oxc team’s claim is that roughly 80% of ESLint users can switch and have it “just work.” The interesting part is how they got there: an ESLint-compatible plugin API running beside the native Rust rules, so you keep your rules and only pay JavaScript prices for the rules that actually need JavaScript.
