Mastonaut news: I’ve recently decided to make Mastonaut open-source. I no longer have the time and energy needed to maintain the app, and it has started to lag in features and functionality when compared to the Mastodon web client and other apps.

The app is now free at the App Store. If you have recently purchased the app at full price, please reach out to App Store support and request a refund. App developers can not process refunds at all, you must go through the App Store support.


The source code is licensed under GPLv3 because I don’t want random jokers to simply clone it and start selling it without putting a single ounce of effort into it. However, if you do make improvements, you’re welcome to sell it (as per GPLv3).

Please not that I’m not a GNU egg head, and so if you wanna make use of parts/whole of the project in your own project that’s licensed differently, reach out and let’s chat.

But overall I wanna thank everyone who has purchased, used, and provided feedback on Mastonaut over the years. It was an extremely fun project to work on and I’ve learned a lot while doing it. I still believe in the future of the fediverse. Consider me making Mastonaut OSS my most recent bet on it. It’s just that I can only focus on so many things at once.

@brunoph Just wanted to say thank you. I’ve been using Mastonaut for years, and it’s great. Hands down my favorite Mastodon app. I’m glad that you’re making it open source, instead of letting it fade.

@brunoph thanks for all your hard work on a great app, Bruno!

@brunoph Great of you to do so! Mastonaut is still the most beautiful way to use Mastodon :ablobcatattention:

@brunoph Thank you for your efforts with Mastonaut. Still my preferred way to see what is going on in the Fediverse.

@brunoph As somebody who is not well-versed in the nuances of these licenses, can you please explain how GPLv3 accomplishes this versus, say, v2 or MIT or Apache etc.?

@jay it doesn’t really prevent anyone from doing it, but someone who is likely to do such a thing is also likely not going to comply with the license. It’s mostly just a canary.
