Grok Build is open source

Grok Build is SpaceXAI's terminal-based AI coding agent. It runs as a full-screen TUI that understands your codebase, edits files, executes shell commands, searches the web, and manages long-running tasks — interactively, headlessly for scripting/CI, or embedded in editors via the Agent Client Protocol (ACP).

Grok Build TUI

Learn more about Grok Build at x.ai/cli

This repository contains the Rust source for the grok CLI/TUI and its agent runtime. It is synced periodically from the SpaceXAI monorepo.

Installing the released binary

Prebuilt binaries are published for macOS, Linux, and Windows:

curl -fsSL https://x.ai/cli/install.sh | bash   # macOS / Linux / Git Bash
irm https://x.ai/cli/install.ps1 | iex          # Windows PowerShell
grok --version

See the changelog for the latest fixes, features, and improvements in each release.

Requirements:

  • Rust — the toolchain is pinned by rust-toolchain.toml; rustup installs it automatically on first build.
  • protoc — proto codegen resolves bin/protoc (a dotslash launcher) or falls back to a protoc on PATH / $PROTOC.
  • macOS and Linux are supported build hosts; Windows builds are best-effort and not currently tested from this tree.
cargo run -p xai-grok-pager-bin              # build + launch the TUI
cargo build -p xai-grok-pager-bin --release  # release binary: target/release/xai-grok-pager
cargo check -p xai-grok-pager-bin            # fast validation

The binary artifact is named xai-grok-pager; official installs ship it as grok. On first launch it opens your browser to authenticate — see the authentication guide.

Full online documentation is available at docs.x.ai/build/overview.

The user guide ships with the pager crate: crates/codegen/xai-grok-pager/docs/user-guide/ — getting started, keyboard shortcuts, slash commands, configuration, theming, MCP servers, skills, plugins, hooks, headless mode, sandboxing, and more.

Important

The root Cargo.toml (workspace members, dependency versions, lints, profiles) is generated — treat it as read-only. Prefer editing per-crate Cargo.toml files.

cargo check -p <crate>        # always target specific crates; full-workspace builds are slow
cargo test -p xai-grok-config # per-crate tests
cargo clippy -p <crate>       # lint config: clippy.toml at the repo root
cargo fmt --all               # rustfmt.toml at the repo root
