Open-source Timely 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.

Kimai is a professional time-tracking application that is free and open source. It handles use cases from solo freelancers to companies with dozens or hundreds of users, letting people record the time they spend on customers and projects, review timesheets and produce reports and invoices.

The feature list includes a JSON API, invoicing, data exports, multiple timers, a punch-in and punch-out mode, tags, multi-user support with multiple time zones, and translations into more than 30 languages. For security and administration it offers authentication via SAML, LDAP or the local database, two-factor authentication with TOTP, customizable role and team permissions and a responsive design. The application is built with PHP and Symfony.

Kimai is licensed under AGPL-3.0 and can be run on-premises on your own server, or you can use the SaaS version offered by the project. It suits freelancers, agencies and small and mid-sized companies that bill by the hour and want to keep time data under their control.

Ever Teams is an open work and project management platform from Ever Co, described as the workplace for humans. It combines project and task management with time tracking, and its topics position it as an alternative to tools such as Jira and Linear, with kanban boards, issue tracking and team management.

The README states the platform is in active development, so it should be used with caution. Planned features include workforce management, time and activity tracking, productivity metrics, projects, tasks and issues, organizations and teams, tags and labels, integrations with GitHub, GitLab, Bitbucket and Jira, and dark, black and light themes. It ships as a web platform, mobile apps for iOS and Android built with React Native and a browser extension, and it uses the headless APIs of Ever Gauzy, the company's open business management platform.

Hosted web, demo and staging applications are linked from the repository, along with documentation and a Storybook for the UI kit. Ever Teams is written in TypeScript and licensed under AGPL-3.0.
