Beeper Mini, the Android app born from a reverse-engineering of Apple's iMessage service, is currently broken, and it is unknown whether it will resume functioning.

Beeper desktop users received a message from co-founder Eric Migicovsky late on Friday afternoon, noting an "iMessage outage" and that "messages are failing to send and receive." Reports had started piling up on Reddit around 2:30 pm Eastern. As of 5:30 pm, the app was still reporting errors in sending and receiving messages, with "Failed to lookup on sever: lookup request timed out." Comments on Beeper's status post on X (formerly Twitter) suggested mixed results, at best, among users.
