What is Grok Build?
Grok Build is xAI's coding agent and CLI. It runs in your terminal, plans and executes multi-step work on its own, and can run up to eight agents in parallel — including managing your social media with Postiz. It is not the Grok chatbot on X, and it is different from Grok Bot, xAI's always-on cloud agents.
Terminal Native
Talk to Grok Build right in your terminal. No browser or extra app — type what you want and manage your socials next to your code.
Plugins & MCP
Grok Build extends itself with plugins that bundle skills and MCP servers. The Postiz plugin ships both — install once and go.
Parallel Agents
Grok Build runs several agents at once. Schedule a week of content in one while another refactors your code.
