Preparing the database

To run the webapp, you first need a database created and filled by repology-updater as explained in its documentation.

Running the webapp

Repology is a flask application, so as long as you've set up database and configuration, you may just run the application locally:


and point your browser to to view the site. This should be enough for personal use, experiments and testing.

Alternatively, you may deploy the application in numerous ways, including mod_wsgi, uwsgi, fastcgi and plain CGI application. See flask documentation on deployment for more info.

For instance, you can deploy with uwsgi with the following command line arguments:

uwsgi --mount /=repology-app:app --pythonpath=<path-to-repology-checkout>
