Kimai is mature, actively maintained, AGPL-3.0 licensed, and explicitly supports self-hosting via Docker or a manual installation. It’s also built around the things freelancers actually need: clients, projects, activities, hourly rates, reports, exports, and invoicing. ([kimai.org](http

Kimai — best overall for an agency - Customer → project → activity hierarchy - Billable/non-billable time - Rates can be defined per customer, project, activity, user, or even user-specific combinations.

  For a distributed team across multiple time zones, I’d start with Kimai.

You can self-host it or use their hosted service. ([github.com](https://github.com/kimai/kimai?utm_source=openai)) The main options I’d consider ar

  For a law firm, I’d start with Kimai. It’s one of the better fits if the requirement is genuinely self-hosted rather than merely “private cloud.” Kimai supports customers, projects/matters, activities, billable vs. non-billable entries, per-user/project rates, timesheets, reporting, invoicing, and exports. Its hierarchy maps reasonably naturally to a firm: Customer = client, Project = matter/case

• Alternatives · Sep 8, 2026

  Yes. If by “popular cloud-hosted tools” you mean products like Toggl Track, Clockify, Harvest, Hubstaff, or Time Doctor, there are several credible open-source/self-hosted replacements. - Kimai — probably the strongest general-purpose choice for a company. It supports multiple users, projects/customers, timesheets, reporting, invoicing, permissions, and related business workflows. It's AGPL-3.0 a

  The main split is this: individual developers benefit most from automatic, low-friction tracking; team leads need structured projects, users, permissions, and aggregate reporting. - ActivityWatch — best for individual developers. It automatically records application/window use, browser activity, AFK time, and can integrate with editors. Data is stored locally by default, so it's particularly good

  Yes. There are two particularly sensible ways to do this, depending on whether you want one integrated application or a modular stack. For most small businesses/consultancies, I'd start with Kimai. It is designed specifically around self-hosted time tracking and already has customers, projects, activities, billable rates, invoice templates, and an API. Its official Docker deployment makes it rela
