What you need to do

Free for any use, commercial included. If you change the code and people outside your company use it over the network, you must publish your changes under the same license.

The apps are AGPL-3.0-or-later; directories with their own LICENSE file, such as packages/server, use that license instead.

AGPL-3.0-or-later (Joplin Server has its own license) · Open source (copyleft). OSI-approved license that requires sharing changes under the same license when you distribute (AGPL: also when you offer it over a network).
