# Grok Build Goes Open Source SpaceXAI's terminal-based AI coding assistant is now publicly available. - **Source:** [Hacker News](https://news.ycombinator.com) - **Published:** 2026-07-15 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/d1cf3c81-6e75-4974-a2bd-a06f9942e9d7 ## What is Grok Build? Developed by SpaceXAI, Grok Build is a terminal-based AI coding assistant. It features a full-screen text interface that understands codebases, edits files, executes shell commands, and streamlines developer workflows. It stands out with its ability to run both interactively and in headless mode. ## Technical Specifications Written in Rust, Grok Build offers pre-built binaries for macOS, Linux, and Windows. It uses protocol buffers and requires 'protoc'. It can be embedded in editors via Agent Client Protocol (ACP). The codebase is periodically synced from SpaceXAI's monorepo. ## Installation Options Users can install pre-built binaries with simple commands: curl and bash for macOS/Linux, PowerShell script for Windows. For source builds, Rust toolchain and protoc are required. Can be tested with 'cargo run' command. ## Documentation and Usage Comprehensive project documentation is available online. The user guide includes details about keyboard shortcuts, slash commands, configuration options, and theming. First run requires browser-based authentication. ## Code Structure and Contribution The repository is organized into Rust crates: TUI components, agent runtime, tool implementations, and workspace management modules. Developers can target specific crates for quick testing. Contributions are accepted under Apache 2.0 license. ## Impact on Developer Ecosystem Grok Build going open source makes significant contribution to AI-assisted development tools ecosystem. Being Rust-based offers performance advantages, while multi-platform support and extensible architecture create new opportunities for developers. ## Sources covering this story - https://github.com/xai-org/grok-build — --- _Summary written by Brifing from the original reporting.
