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:

```bash
grok plugin install browser-use --trust
```

Launch Grok Build in any project workspace:

```bash
grok build
```
