ActivityWatch is a free, open-source, privacy-first time tracker that runs entirely on your machine. It automatically records your active application, window title, browser tab, and AFK (away-from-keyboard) status — giving you a complete picture of how you spend your time without sending any data to external servers.Documentation Index

How ActivityWatch works
ActivityWatch consists of a local server, a set of watchers that collect data, and a web UI for exploring your activity. All data is stored on your machine.Install ActivityWatch
Download the latest release for your platform (Windows, macOS, or Linux) and run the installer. ActivityWatch starts a local server on port 5600.
Watchers collect your activity
Built-in watchers automatically record the active window and application, AFK/idle status, and — with the browser extension — the active browser tab and URL.
