Tag your time, get the insight - an open source time tracker with a focus on a simple and interactive user experience.


TimeTagger is a web-based time-tracking solution that can be run locally or on a server. In the latter case, you'll want to add authentication, and also be aware of the license restrictions.

The server runs on async Python using uvicorn and asgineer - which is fun and bloody fast. It uses SQLite via itemdb to store the data, making it easy to deploy.

The client is a mix of HTML, CSS, Markdown, and ... Python! PScript is used to compile the Python to JavaScript. This may be a bit idiosyncratic, but it's fun! Maybe I'll someday implement it in something that compiles down to Wasm :)

Usage example

This repo is organized as a library, making it quite flexible to apply tweaks. See
for an example of how to run it as a web app.

You can also see it in action at - you can also purchase an account for $2 per month so you don't have to worry about maintaining a server, backups, and all that. Plus you'd sponsor this project and open source in general.
