ActivityWatch is a free, open-source, automated time tracker that records which applications, windows, and websites you use across Windows, macOS, Linux, and Android. All data is stored locally in a SQLite database with a web dashboard, and it is extensible via custom watchers, browser extensions, and editor plugins.

Use cases

  • track how I spend time on my computer automatically
  • open-source alternative to RescueTime
  • monitor productivity and screen time locally
  • track time spent per project or app
  • lifelogging and quantified-self activity tracking
  • measure work-life balance from device usage

When to choose

  • you want privacy-first, local-only time tracking with no cloud upload
  • you need cross-platform tracking including Linux and Android
  • you want an extensible tracker with custom watchers and API access
  • you want a free alternative to RescueTime, ManicTime, or WakaTime

When to avoid

  • you need team time tracking or cloud sync across devices out of the box
  • you need invoicing or billable-hours features for client work
  • you require iOS support
