Biome Has a Free API: One Tool to Replace ESLint, Prettier, and More

ESLint + Prettier + their configs + their plugins + their conflicts = 15 devDependencies and a weekend of debugging. Biome replaces all of it with one binary. What Is Biome? Biome is a fast formatter, linter, and more — written in Rust, designed to replace ESLint and Prettier in one tool. npx @biomejs/biome init # Creates biome.json npx @biomejs/biome check --write . # Format + lint + fix One command. One config file. One tool. Speed Biome formats and lints a 10,000-file monorepo in under 1 second . ESLint + Prettier takes 45+ seconds on the same codebase. How?
