AltStore PAL now supports the fediverse, using its own Mastodon server to let iOS developers share app updates and alerts across platforms like Mastodon and Threads.
To access the AltStore PAL’s Mastodon server, users can visit fosstodon.org/@altstore. Meanwhile, users can also discover apps and sources on the AltStore PAL’s explore page at explore.alt.store. Alongside this update, the AltStore PAL app has been updated with an iOS 26 Liquid Glass design and icon.
