The Consolidation of DevTools
For years, we used Prettier for formatting, ESLint for linting, and various plugins to glue them together. Biome changes this by providing a single, unified Rust binary that does everything.
### Performance Breakdown
In a project with 5,000 files, Prettier can take 15-20 seconds to format on a standard CI runner. Biome completes the same task in under 0.2 seconds. This isn't just a minor improvement—it's a workflow transformation.
### Privacy and Local Execution
Both tools run locally, but Biome's lack of complex Node.js dependency trees makes it less prone to the "supply chain attacks" that have occasionally plagued the npm ecosystem. Biome is a self-contained binary, making it easier to audit.
