VERDICT

Should I use Biome?

Format, lint, and more in a fraction of a second. - biomejs.dev

Worth it. JS/TS teams wanting one free, fast tool instead of ESLint plus Prettier should adopt it — Ant Design and Astro already do. Teams dependent on ESLint's plugin ecosystem or non-JavaScript languages should stay on their current stack.

Confidence

Medium. Based on 14 usable public sources. Many 'Biome' search hits were unrelated brands (gut supplements, flooring, games, a biotech) and were discarded. No formal review ratings exist for this tool; word-of-mouth comes from Reddit, YouTube, and official pages.
