xAI updated Grok Build with the Grok 4.6 model and introduced native Browser Use support through its official plugin registry.

Grok Build terminal agent powered by Grok 4.6 and native Browser Use

Grok Build is a terminal-native developer assistant that lives where engineers work: the command line. With Grok 4.6 at its core and native browser execution capabilities, it handles end-to-end software engineering workflows directly in your local environment.

What is Grok Build?

Grok Build operates inside your terminal workspace rather than an isolated chat window or web sidebar. It maintains deep system-level access to read, analyze, edit, test, and run code directly on your local repositories.

Powered by Grok 4.6, the agent provides:

  • Deep Code Comprehension: Analyzes complex architectures and multi-file dependencies across major programming languages.
  • Autonomous Planning and Execution: Deconstructs complex tasks into structured steps, executes commands, inspects outputs, and self-corrects on errors.
  • Fast Feedback Loops: Operates with low latency directly in zsh or bash environments without context switching.

Native Browser Use Plugin

The latest update introduces the official browser-use plugin, enabling Grok Build to interact directly with web browsers during development and testing loops.

The plugin supports two execution modes:

  • Local Chrome Browser: Connects to your local Chrome instance with existing cookies, authentication sessions, and state intact.
  • Isolated Cloud Browser: Runs inside a sandboxed cloud browser environment for clean or automated runs.

Key Capabilities

With Browser Use active, Grok Build can perform:

  • Browsing and Navigation: Access dynamic web pages and inspect live DOM trees in real time.
  • Data Scraping and Extraction: Collect structured data and assets directly from websites.
  • Form Automation and Interaction: Fill out inputs, trigger buttons, and navigate multi-step user flows.
  • End-to-End Web App Testing: Verify UI functionality and test user flows against running local or staging servers.
  • Visual Snapshot Verification: Capture screenshots to confirm rendering and layout correctness.
  • Multi-Step Web Workflows: Automate repetitive multi-page web operations autonomously.

Installation and Quick Start

Install the official Browser Use plugin directly using the Grok CLI:

grok plugin install browser-use --trust

Launch Grok Build in any project workspace:

grok build
