Rome

Rome is an all-in-one toolchain for JavaScript, TypeScript, CSS, and JSON. At version 12.1.3 (pre-1.0), it provides a unified formatter, linter, and bundler with 80+ built-in lint rules. It is designed to replace multiple tools like Prettier, ESLint, and Babel, with a focus on speed and correctness. Released monthly, it is written in Rust and offers a single binary with no configuration required for basic use. Key differentiators: no config, fast execution, and unified API. Note: Rome is currently in the process of being renamed to Biome (as of late 2023), but v12.1.3 is still under the Rome name.
