OpenBot tested as open Grok Bot alternative, missing Gmail and Drive integrations
The author moved his bots from Grok Bot to OpenBot, using Terra 6.1 by default and Opus 5.5 for advanced bots, and flags the lack of native multi-account Gmail and Drive integrations as the main pain point.

I've been testing @OpenBot_ (open alternative to Grok Bot) and I have to admit it's one of the coolest apps I've seen for a while. And it's made in Poland! I fully moved my bots from grok - Terra 6.1 as default (as fast and more intelligent than grok) - Opus 5.5 for advanced bots (research, code) My biggest paint point right now - lack of native multi account integrations with with Gmail and Drive, grokbot has it, but I suspect it will come.
