Biome Replaces ESLint and Prettier in Production JavaScript Projects

Biome reached v2.0 with full ESLint rule parity on 95% of common rules and Prettier-compatible formatting. Built in Rust, it's 40% faster than ESLint and 10x faster than Prettier. Major projects including Astro, Vue DevTools, and several Vercel internal projects have migrated from ESLint + Prettier to Biome.

ESLint + Prettier + TypeScript checker + dozens of plugins has become a notoriously complex stack for modern JS projects. Biome consolidates these into one fast, opinionated tool. This reduces config file sprawl, improves CI performance, and simplifies onboarding for new developers.

ESLint's market dominance faces real pressure. Some major linting rule authors are building Biome compatibility. Prettier remains sticky due to formatting opinion strength. Meanwhile, TypeScript teams continue using `tsc` separately — Biome doesn't yet type-check, which is a key adoption blocker.

Watch for Biome adding TypeScript type-checking (Rome's original goal before the project split). Oxc (a competing Rust linter) is also gaining traction and may merge toolchains with Biome. Also track ESLint's response — their flat config and plugin performance improvements are narrowing the gap.
