Kimai

Description

Kimai is an open-source time-tracking application for freelancers and teams, and a self-hosted alternative to Toggl, Harvest, and Clockify. Entries are recorded against a three-level structure of customers, projects, and activities, which makes reporting and billing straightforward. Rates can be hourly or fixed and vary per user or per project; budgets warn when a project runs long; and finished timesheets can be locked so they are not edited after invoicing. A plugin marketplace extends it with features like expenses, approval workflows, and custom exports.

Features

• Structured tracking: Customer → project → activity hierarchy with tags and descriptions.
• Rates & budgets: Hourly and fixed rates per user/project, rounding rules, and time/money budgets.
• Invoicing: Generate invoices from customizable templates (PDF, DOCX, HTML) directly from timesheets.
• Exports & reports: CSV, XLSX, ODS, and PDF exports plus weekly, monthly, and per-user reports.
• Team controls: Teams, permissions, timesheet approval, and lockdown of past periods.
• Integration: REST API, 2FA, and LDAP / SAML single sign-on.
