SpaceXAI Open-Sources Coding Agent Grok Build on GitHub

SpaceXAI has open-sourced Grok Build, its coding agent and interface, on GitHub with full support for local-first operation using custom inference instances. The release includes the agent loop, tool system, UI rendering, and an extensible plugin architecture. You can now run a production-grade coding agent on your own hardware with no vendor lock-in. This moves the economics of AI coding tools from per-seat SaaS to self-hosted infrastructure — your customer acquisition cost just dropped and your moat just shifted from the model to the integrations.
