Stoat (software)

Stoat is a free and open-source, user-first communication platform and instant messaging service. Designed as an alternative to proprietary services like Discord, Stoat allows users to communicate through text, voice, and media within organised communities called "servers". The platform is notable for its emphasis on privacy, its use of the Rust programming language for its back-end, and its support for self-hosting. Stoat is available on Windows, Linux, macOS, Android, and iOS.

History

The platform went live for the first time on January 27, 2021, and opened for public beta on August 11 of the same year. On September 6, 2021, the platform had its first major influx of users after reaching the front page of Hacker News.
On June 13, 2023, the platform announced it had reached 100,000 registered users following a surge in users spurred by the release of an updated username system.
In October 2024, the platform experienced a significant surge in users, reaching over 500,000 registered accounts following regional bans on Discord in countries such as Turkey and Russia.
On October 1, 2025, the development team announced a rebranding from Revolt to Stoat. This change was necessitated by a cease and desist letter regarding the "Revolt" trademark. The rebranding was accompanied by the release of a new client for web and desktop, the launch of a new voice chat system, and the migration of all official repositories to the "stoatchat" organisation on GitHub.

Controversies

In late 2022, the lead developer of Stoat reported that a platform operated by influencer Andrew Tate, known as "The Real World", was using a modified version of the Revolt back-end and web app. The developers alleged that this was a violation of the AGPLv3 license, as the source code for the modifications was not made public despite the platform generating significant revenue. In November 2024, the platform using the modified software suffered a major data breach, exposing the records of approximately 800,000 users.
