caniuse-cmd

caniuse‑cmd is a command‑line interface that queries the data from caniuse.com to report browser support for web features. After installing globally via npm, users can invoke the tool with a feature name such as “websockets” or “input” and receive a formatted table showing support status, version ranges, and usage percentages for major browsers. The output can be colored or rendered in ASCII, and includes notes about partial or prefixed support.

The utility targets front‑end developers and build engineers who need quick, scriptable access to compatibility information without opening a web page. It offers a range of flags to control the detail level—short, long, one‑line, or with abbreviated browser names—and to filter results by platform, version era, or specific browsers. A configuration file in the user’s home directory allows defaults to be set for recurring queries.

All functionality is provided through a single executable, making it suitable for inclusion in shell scripts, CI pipelines, or interactive terminal sessions where developers require up‑to‑date compatibility data in a lightweight, non‑graphical form.
