What it does
Kimai is an open-source time tracker for project-driven teams. Its official page describes time analysis by users, customers, projects, activities, tags, and periods, along with configurable invoice templates and client/project statistics. The same platform can be self-hosted or used as a hosted cloud service.
Kimai supports project and customer time tracking, with analysis by user, project, activity, tag, and time period. The vendor also lists configurable invoice templates, timesheet and project reports, and plugins for additional features. The code is released under AGPL-3 and can be self-hosted; Kimai Cloud is an optional hosted service with per-user subscriptions and a 30-day trial.
The cloud pricing page lists Standard at €2.99 per user/month on annual billing or €3.99 monthly, and Professional at €3.99 annually billed or €4.99 monthly. Self-hosting avoids the SaaS subscription but shifts installation and maintenance to the team. No deployment or invoice was tested.
