Open-source Time Doctor alternatives

ActivityWatch is an open-source application that records what you do on your computer so you can see how you spent your time. Its guiding goal is to let people collect as much valuable lifedata as they like without compromising privacy, so everything is stored securely on your own machine and you control what is gathered.

Data comes from small programs called watchers. The standard ones record the currently active application and its window title, the active browser tab with its title and URL, and keyboard and mouse activity to work out whether you are away from the keyboard. You decide how much to collect, and community members are encouraged to write more watchers. The repository also includes a server and libraries, and the project provides a feature comparison with other time trackers.

ActivityWatch is written mainly in Python, is MPL-2.0 licensed and works across Windows, macOS and Linux. It has a forum, documentation and a newsletter. It appeals to people who want automatic time tracking and productivity analytics without sending activity data to a cloud service.

Solidtime is a contemporary time tracking application for freelancers and agencies, released as open source. It provides an easy-to-use interface for logging time against projects and tasks, and is built with Laravel and Vue.

Beyond tracking time, you can create and manage projects with members, tasks inside projects, and clients attached to projects. Billable rates can be set for projects, project members, organization members and whole organizations. One account can manage multiple organizations, roles and permissions control access, and data can be imported from Toggl, Clockify and generic time entry CSV files.

Solidtime can be self-hosted using the published guides and an examples repository, or used through solidtime cloud if you do not want to run it. It is licensed under AGPL-3.0, and the contributing rules ask for an issue or discussion before pull requests. It suits small teams moving off Toggl or Clockify who want billing-friendly reports and control over their data.
