Currently not open source, but it will be! The code base is just a bit messy this early on and @hariette is focusing on cleaning up a few bugs prior to the larger beta roll out. Once things slow down on the development side, the devs can focus on cleaning up the codebase and releasing it on GitHub.
Source: From this toot on Mastodon by Hariette.
Short answer: Not right now, but it will be.
Will the code be public in the future?
