SpaceXAI open-sources Grok Build, its AI coding agent for the terminal

SpaceXAI has released Grok Build as an open-source project on GitHub. This is a terminal-based AI coding agent that goes far beyond simple chat. It runs as a full-screen text user interface (TUI) that continuously analyzes your entire codebase, letting you edit files, run shell commands, search the web, and manage long-running tasks without leaving the terminal. The agent is built in Rust and is designed for both interactive use and headless automation, making it suitable for scripting, continuous integration pipelines, and other automated workflows. It also integrates with editors via the Agent Client Protocol (ACP), a standardized interface for embedding AI agents into development environments. Prebuilt binaries are provided for macOS, Linux, and Windows, with installation via a simple curl or PowerShell script.

The open-source repository contains the Rust source code for the CLI/TUI and agent runtime, synced periodically from SpaceXAI's internal monorepo. The project is licensed under Apache 2.0, with third-party dependencies maintaining their original licenses. Notably, SpaceXAI states that external contributions are not accepted, meaning the community can inspect and modify the code for personal use but cannot submit pull requests. The repository includes comprehensive documentation covering user guides, keyboard shortcuts, slash commands, theming, MCP servers, plugins, sandboxing, and headless mode. This release marks a significant step in making powerful, terminal-native AI coding agents freely available to developers, though SpaceXAI maintains tight control over the project's direction.
