Detailed Introduction
Kimai is a professional-grade, self-hosted time tracking application designed for freelancers, small businesses, and large enterprises. It offers a rich set of features including a JSON API, invoicing, data exports, multi-timer and punch-in/out modes, tagging, multi-user and multi-timezone support, over 30 language translations, authentication via SAML/LDAP/database, two-factor authentication (TOTP), customizable role and team permissions, responsive design, user/customer/project-specific rates, advanced search and filtering, budgets, and detailed reporting. It supports plugins from an official marketplace and can be deployed via Docker, Git, or synology. Kimai is built with PHP 8.2+, Symfony, and Doctrine, requiring a MySQL/MariaDB database. It gives users complete control over their time data, avoiding vendor lock-in and recurring subscription costs.
Troubleshooting & FAQ (2)
TroubleshootingHow to fix Kimai error "Unable to find template @invoice/din5008-invoice.pdf.twig" when previewing an invoice?
Reload Kimai and fix file permissions so the web server can read the custom invoice template. From the Kimai root directory (or inside the Docker container) run:
bin/console kimai:reload --env=prod
chown -R :www-data .
chmod -R g+r .
chmod -R g+rw var/Wait briefly for the cache/reload to complete, then try the invoice preview again. If using Docker, run these commands inside the container and verify that the volume containing var/invoices/din5008-invoice.pdf.twig is mounted correctly.
TroubleshootingWhy do Kimai dashboard widgets not appear in the saved order or position?
In Kimai 2.15.x, the dashboard grid can render widgets differently from the edit mode, especially when widgets of different sizes are placed in the same row. The saved layout may therefore appear reordered or repositioned. As a workaround, arrange widgets so each row contains only widgets of the same size. A fully refactored dashboard that fixes this behavior is planned for Kimai 3.0.
