More than 300,000 people have signed up on Fluxer.app so far. Today we're releasing Fluxer v2, open source mobile apps in beta and big improvements to self-hosting and safety. Self-hosting means running Fluxer on your own server.

We're also accepting code contributions to the Fluxer repository on GitHub again. People in the community have built their own Fluxer apps, tools and bots.

We couldn't do this without all of you. You talk about Fluxer, subscribe to Plutonium on Fluxer.app, donate, report bugs, build things and test the rough edges. Volunteers have put thousands of hours into Fluxer over the last few months. Thank you.

If you're new, these two posts explain how Fluxer started and what's next.

With v2 out, we can keep the code on GitHub in sync with our day-to-day work again. We can also review pull requests (code changes people send us). Thank you for your patience, and thank you to the dozens of testers who helped launch v2.

The mobile apps are now open source

The iOS and Android apps are built with Flutter and open source on GitHub.

You can use them today by joining the TestFlight beta on iOS or the Google Play beta on Android. Both are on our download page. We're working on making them more stable so they're ready for a full release on the App Store and Google Play. Thanks to @M0N7Y5 and @Elias for all the work they've put into the iOS and Android apps.

Safety and operations

Behind the scenes, we've been working on moderation and on keeping Fluxer.app running. We've dealt with spam attacks, child sexual abuse material (CSAM), extremist content and other abuse, and we've kept improving reliability and uptime.

Closing thoughts

See you in the Fluxerverse!
