Overview

Kimai is a web-based time-tracking platform for freelancers through larger organizations, combining timesheets, customers/projects, rates, budgets, reporting, invoicing, punch-in/out, permissions, and authentication integrations.

Features and best fit

Supplemental curator note

Kimai extends beyond personal time tracking into operational timesheets with customer/project rates, budgets, reports, invoicing, and team permissions. Its plugin marketplace includes both free and paid extensions, so distinguish core capabilities from optional paid plugins when evaluating requirements.
