But Biome's growth rate tells a different story: it surpassed 15 million monthly downloads in 2025 and shows no signs of slowing. Meanwhile, ESLint v10 just shipped in February 2026 — the most significant release in years. We compared both tools using real data from PkgPulse . Here's what the numbers say.
