Grok Build is a terminal-based coding agent developed by Elon Musk's SpaceXAI that uses the Grok 4.6 large language model. It reads and writes files, runs commands, and spawns sub-agents to handle large codebases directly within your development environment. Installation is simple: Windows users run irm https://x.ai/cli/install.ps1 | iex in PowerShell, while macOS and Linux users execute curl -fsSL https://x.ai/cli/install.sh | bash in Terminal. After navigating to your codebase folder with cd, the grok command launches the interface and prompts an X account login.

Grok Build features built-in mouse support but requires a separate editor like Visual Studio Code for manual code changes. It can explain codebases, install dependencies, run web servers, build apps from scratch, and guide deployment. Access depends on your Grok plan: free users exhaust tokens quickly, while paid plans offer higher limits. All AI processing occurs in the cloud, making it compatible with most computers.

Unlike full IDEs such as Google's Antigravity, Grok Build operates within a terminal window, integrating into existing workflows. It represents a newer entrant in the coding agent space alongside established competitors. The tool is designed for developers working on larger projects where copying AI-generated code between chat windows and editors becomes inefficient.
