BotCloud in BotFather is now available to a limited number of users. Telegram has started sending invitations to test the new Bot API with BotCloud support.

With BotCloud, developers will be able to run bots, JavaScript code, and databases directly on Telegram's infrastructure, without the need to maintain their own servers.

For now, access is by invitation only, while the documentation is already available to testers.
