Watchexec

Universal watcher that runs commands when files change

About Watchexec

A simple, standalone tool that watches a path and runs a command whenever files change, with glob filtering, environment control and a library used by many other developer tools. It is free and open source, so teams can self-host it, inspect the code and adapt it to their own infrastructure without licence fees or vendor lock-in. Typical users run it alongside existing workflows to cut manual effort, improve visibility and keep full control over data, configuration and upgrades over time.
