The bottom line

Pricing: Kimai is completely free (Free, open source, self-hosted), which makes it the obvious pick if budget is the top concern. Hubstaff starts at $4.99/user/mo, but Free for 1 user. That cost buys you a more polished or feature-rich experience, so it comes down to whether the extras justify the spend.

Feature gaps: Kimai offers API, Multi-user and Reporting that Hubstaff lacks. Hubstaff brings GPS tracking, Invoicing and Payroll that Kimai does not have. Both share Time tracking.

Open source: Kimai is open source, meaning you can self-host, audit the code, and avoid vendor lock-in. Hubstaff is proprietary — you are trusting the vendor with your data and uptime.

Where each tool shines: Kimai's biggest strengths are: completely free and open source — no per-user fees. self-hosted means you own your data entirely. Hubstaff's biggest strengths are: activity monitoring provides accountability for remote teams. built-in payroll and invoicing saves additional tool costs.

Watch out for: With Kimai, users commonly note that requires self-hosting — not a cloud saas you can just sign up for. With Hubstaff, the main complaint is that screenshot monitoring can feel invasive to employees.
