Cattr server application - self-hosted time tracking with project management, reports, screenshots, activity tracking and public API

← Running in production

In simple English

This tool lets you track hours, projects, and tasks for your team on your own server. It records screenshots and activity levels to show how work gets done. You can view reports and use a public API to connect other apps. It costs you the time to set up and maintain a server.

What it is

Cattr Server is a PHP (a programming language used to build websites) backend application for self-hosted time tracking and project management. It pairs with a desktop app to capture screenshots and track user activity.

What it is good for

This is good for agency owners and team leads who want to track staff hours and view work logs on their own infrastructure without paying a monthly fee to a third-party service.
