# Biome

23 Hacker News commenters recommended Biome and 5 criticized it, November 2025 to November 2026. It was recommended in 10 of 13 months. It meets the Hacker Approved badge rule.

**Verdict:** Fast free JavaScript and TypeScript formatter and linter that replaces ESLint and Prettier in one tool; critics say mixed-language files like Vue and Svelte work poorly.
