The right time tracking app for Linux depends on what you need to record. Clockify offers a conventional timer and manual entries through a Linux desktop companion, with reports and timesheet review in the browser. Kimai suits project-driven teams that need customer and project records, analysis, exports, and invoicing, with self-hosted and SaaS options. ActivityWatch automatically records personal computer activity, rather than serving as a ready-made billable team timesheet.
Choose by how you want to track time
| App | Best fit | How tracking works | Linux setup and data |
|---|---|---|---|
| Clockify | Freelancers or individuals tracking time against projects | Start or continue a timer, or add time manually; the desktop app also describes automatic app and website tracking. | Linux desktop app for Intel 64-bit and ARM 64-bit, with Debian/Ubuntu and Red Hat (CentOS/Fedora) downloads listed. Requires an account and browser authentication; reports and timesheet review are in the browser. |
| Kimai | Teams organizing time by customer, project, and activity, especially where self-hosting or invoicing matters | Project and team time records analyzed through Kimai; Linux desktop clients are separate integrations that connect to a Kimai server. | Self-hosted installation (including Docker or manual installation) or SaaS. The official integrations directory lists Linux-compatible clients; check each one’s current release and requirements. |
| ActivityWatch | Individuals who want to understand computer-use patterns | Automatically records active application/window and inferred idle status; optional browser watchers can add website detail. | Linux downloads include AppImage. The project says data stays on-device; synchronization is still in progress. |
Clockify: a conventional timer with a Linux desktop app
Clockify is primarily a browser app with a Linux desktop companion for time entry, according to its Linux product page. In the desktop workflow, you can start or continue a timer and attach a description, project, task, tag, and billability status. Manual mode lets you enter time afterward if you forgot to start the timer. Its help page also documents settings to start the timer when the app opens or stop it when the app quits.
Plan on an account: Clockify’s Linux app help page says authentication happens through the browser. Use the browser for reports, project management, and timesheet review; the desktop app is not described as a fully native, offline-first replacement for the service.
The Linux product page lists Intel 64-bit and ARM 64-bit, with Debian/Ubuntu and Red Hat (CentOS/Fedora) downloads. Check that the current package matches your distribution and processor architecture before installing. The page also describes an auto-tracker for app and website use and a Ulauncher extension; consider what activity information you are comfortable recording before enabling automatic tracking.

Kimai: project and team time records, hosted your way
Kimai is open-source software under AGPL 3, and its official site offers both self-hosting and SaaS. For self-hosting, it lists Docker and manual installation. Choose self-hosting if you want to operate the server yourself; SaaS avoids that server-administration work, but the hosting and operational terms should be checked with the provider.
Kimai’s feature documentation covers analysis by user, customer, project, activity, tag, and time period; configurable invoicing; XLSX, PDF, CSV, and HTML exports; a JSON API; optional TOTP two-factor authentication; a customer portal; and a time-clock mode for punch-in and punch-out. Those features make it a stronger candidate than a personal activity tracker when the workflow centers on project records and client billing.

The clarity of the display is exceptional, with crisp digits that make it easy to read the time at a glance.

The project says activity data stays on the device, and its homepage says synchronization is still in progress. That makes it a different choice from a hosted team timesheet: the reviewed project pages describe activity capture and categories, not a complete system for team approvals, invoicing, or payroll. Treat automatically recorded activity as a personal record to review, not as an automatic decision about which minutes are billable.
Which Linux time tracker should you choose?
- For straightforward project timers: Evaluate Clockify if you are comfortable with an account and browser-based authentication. Verify the current Linux installer for your distro and architecture.
- For team timesheets, reporting, and invoicing: Evaluate Kimai, comparing the work of self-hosting with its SaaS option. If you want a Linux desktop client, treat it as a separate integration and verify its current status.
- For understanding your own computer-use patterns: Evaluate ActivityWatch if automatic window and idle tracking fit your needs and local data storage is appropriate for your situation.
Privacy and setup checks before you begin
Time records can reveal client names, project schedules, work habits, and periods of inactivity. Automatic monitoring may capture more sensitive context than a manually started timer, particularly when window titles or browser activity are recorded. Before enabling watchers or using any tracker for employee monitoring, establish what is captured, who can see it, and where records are stored.
