Show HN: Vibium – Browser automation for AI and humans, by Selenium's creator

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. New here? Getting Started Tutorial - zero to hello world in 5 minutes.

JS developers just npm install vibium and it works. // Option 1: require (REPL-friendly) const { browserSync } = require('vibium') // Option 2: dynamic import (REPL with --experimental-repl-await) const { browser } = await import('vibium') // Option 3: static import (in .mjs or .ts files) import { browser, browserSync } from 'vibium' Sync API: const fs = require('fs') const { browserSync } = 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 npm install vibium 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\ Linux: No manual browser setup required. Skip browser download (if you manage browsers separately): VIBIUM_SKIP_BROWSER_DOWNLOAD=1 npm install vibium Platform Architecture Status...
