There are dozens of ways to contribute in Weblate. Any help is welcomed, be it coding, graphics design, documentation or sponsorship.
Code and development¶
Weblate is developed on GitHub. You are welcome to fork the code and open pull requests. Patches in any other form are welcome too.
Check out Internals to see how Weblate looks from inside.
The code should follow PEP-8 coding guidelines. It is recommended to format new code using black code formatter (though existing code is yet formatted).
To check the code quality, you can use flake8, the recommended
plugins are listed in
You can execute all coding style checks with the script
Security by Design Principles¶
Any code for Weblate should be writted with Security by Design Principles in mind.
Testsuites exist for most of the current code, increase coverage by adding testcases for any new functionality, and verify that it works. Current test results can be found on Travis and coverage is reported on Codecov.
To run a testsuite locally, use:
DJANGO_SETTINGS_MODULE=weblate.settings_test ./manage.py test
You can also specify individual tests to run:
DJANGO_SETTINGS_MODULE=weblate.settings_test ./manage.py test weblate.gitexport
The tests can also be executed inside developer docker container, see Running Weblate locally in Docker.
See Testing in Django for more info on running and writing tests for Django.
Our issue tracker is hosted at GitHub:

Starting with our codebase¶
If looking for some bugs to familiarize yourself with the Weblate codebase, look for ones labelled good first issue.
Quick overview of directory structure of Weblate main repository:
Running Weblate locally in Docker¶
If you have Docker and docker-compose installed, you can spin up the development environment simply by running:
It will create development Docker image and start it. Weblate is running on
<http://127.0.0.1:8080/> and you can login with
admin user and
password. The new installation is empty, so you might want to continue with
Adding translation projects and components.
docker-compose.yml for this are located in
The script also accepts some parameters, to execute tests run it with
parameter and then specify any
test parameters, for example:
./rundev.sh test --failfast weblate.trans
To stop the background containers run:
Running the script without args will recreate Docker container and restart it.
This is not suitable setup for production, it includes several hacks which are insecure, but make development easier.
Weblate is being translated using Weblate itself, feel free to take part in the effort of making Weblate available in as many human languages as possible.
