## What it is
Kimai is a professional open-source, web-based, multi-user time-tracking application built with PHP/Symfony. It supports timesheets, invoicing, reporting, exports, SAML/LDAP authentication, and can be self-hosted or used as a SaaS cloud offering.

## Use cases
- track billable hours for client projects
- generate invoices from timesheets
- manage team timesheets and working hours
- track vacation, sick leave and absences
- export time reports for accounting
- self-host a GDPR-compliant time tracker
- track time across multiple users and timezones

## When to choose
- you need a mature, self-hosted time tracker with invoicing built in
- you want multi-user support with SAML/LDAP/2FA authentication
- you need data sovereignty and full ownership of your time data
- you run an agency or company that bills clients by the hour

## When to avoid
- you need a simple personal single-user timer without server setup
- you cannot run PHP 8.2+ with MySQL/MariaDB and a webserver
- you want a native desktop-first tracker rather than a web application
