OpenCrewBot: a reverse-engineered open-source alternative to Grok Bot on open models

Arindam_1729 · x · 2026-10-14

Someone reverse-engineered Grok Bot and released an open-source alternative, OpenCrewBot (MIT licensed). Running on open models, it gives you your own team of AI bots in a single chat app, each with its own model, tools, memory, and cloud browser.

Built with Mastra and Nebius Token Factory, with optional Tavily and Browserbase integrations, fully self-hostable. The repo is very early (4 commits, 3 stars) but the self-hosted, controllable multi-agent chat concept is clear.
