Catullus

Catullus is a transpiler that compiles modern JavaScript syntax to compatible versions for older environments. It acts as a wrapper around Babel and presets to simplify build configuration. The current stable version is 2.0.0, with no active release cadence apparent from the metadata. Key differentiators: it provides a CLI command (catullus babel) and integrates with .babelrc. Compared to plain Babel, Catullus aims to reduce boilerplate but enters a space already well-covered by higher-level tools like Parcel or Webpack. The project appears unmaintained with sparse documentation and limited community adoption.
