Browser automation without the drama.

Vibium is browser automation infrastructure built for AI agents. A single binary handles browser lifecycle, WebDriver BiDi protocol, and exposes an MCP server — so Claude Code (or any MCP client) can drive a browser with zero setup. Works great for AI agents, test automation, and anything else that needs a browser.

A single Go binary (~10MB) that does everything:

Browser Management: Detects/launches Chrome with BiDi enabled
BiDi Proxy: WebSocket server that routes commands to browser
MCP Server: stdio interface for LLM agents
Auto-Wait: Polls for elements before interacting
Screenshots: Viewport capture as PNG

Design goal: The binary is invisible. JS developers just npm install vibium and it works.

// Option 1: require (REPL-friendly)
const What do you think? = require('vibium')

// Option 2: dynamic import (REPL with --experimental-repl-await)
const ⚡ = await import('vibium')

// Option 3: static import (in .mjs or .ts files)
import What do you think? from 'vibium'

Sync API:

const fs = require('fs')
const Share your opinion below! = require('vibium')

const vibe = browserSync.launch()
vibe.go('https://example.com')

const png = vibe.screenshot()
fs.writeFileSync('screenshot.png', png)

const link = vibe.find('a')
link.click()
vibe.quit()

Async API:

const fs = await import('fs/promises')
const { browser } = await import('vibium')

const vibe = await browser.launch()
await vibe.go('https://example.com')

const png = await vibe.screenshot()
await fs.writeFile('screenshot.png', png)

const link = await vibe.find('a')
await link.click()
await vibe.quit()

One command to add browser control to Claude Code:

claude mcp add vibium -- npx -y vibium

That’s it. No manual steps needed. Chrome downloads automatically during setup.

Tool	Description
`browser_launch`	Start browser (visible by default)
`browser_navigate`	Go to URL
`browser_find`	Find element by CSS selector
`browser_click`	Click an element
`browser_type`	Type text into an element
`browser_screenshot`	Capture viewport (base64 or save to file with `--screenshot-dir`)
`browser_quit`	Close browser

This automatically:

Installs the Clicker binary for your platform
Downloads Chrome for Testing + chromedriver to platform cache:
- Linux: ~/.cache/vibium/
- macOS: ~/Library/Caches/vibium/
- Windows: %LOCALAPPDATA%\vibium\

No manual browser setup required.

Skip browser download (if you manage browsers separately):

VIBIUM_SKIP_BROWSER_DOWNLOAD=1 npm install vibium

Platform	Architecture	Status
Linux	x64	✅ Supported
macOS	x64 (Intel)	✅ Supported
macOS	arm64 (Apple Silicon)	✅ Supported
Windows	x64	✅ Supported

As a library:

import { browser } from "vibium";

const vibe = await browser.launch();
await vibe.go("https://example.com");
const el = await vibe.find("a");
await el.click();
await vibe.quit();

With Claude Code:

Once installed via claude mcp add, just ask Claude to browse:

“Go to example.com and click the first link”

See CONTRIBUTING.md for development setup and guidelines.

V1 focuses on the core loop: browser control via MCP and JS client.

See V2-ROADMAP.md for planned features:

Python and Java clients
Cortex (memory/navigation layer)
Retina (recording extension)
Video recording
AI-powered locators

Apache 2.0
