I used to juggle ESLint and Prettier every day.

Two tools. Multiple config files. Plugin conflicts. Slow checks. And that constant feeling that something was always fighting something else.

Then I found Biome.

Biome is a single, Rust-powered tool that does both formatting and linting. It replaces the classic ESLint + Prettier combo with one binary and one simple config.

Why it feels different
It’s extremely fast. According to the official benchmark, Biome formats ~35x faster than Prettier when processing 171,127 lines of code across 2,104 files (on an Intel Core i7 1270P). In real projects, the difference is impossible to ignore — checks that used to take seconds now finish almost instantly.

One tool, one config. No more keeping a linter and a formatter in sync. Biome uses the same parser for both jobs, so they never disagree.

High compatibility, clear feedback. The formatter is about 97% compatible with Prettier. The linter comes with hundreds of solid rules inspired by ESLint and TypeScript ESLint. And when something is wrong, the error messages actually tell you where the problem is and how to fix it.

It just works. You can format, lint, and organize imports in a single command. It supports JavaScript, TypeScript, JSX, JSON, CSS, HTML, GraphQL, and more.

Companies like Vercel, Cloudflare, Discord, Microsoft, and Google are already using it in production. That says something.

I’m not saying you must drop everything tomorrow. But if you’re tired of slow tooling and config complexity, Biome is worth a serious look.

Have you tried it yet?
