Open Browser
AI-powered autonomous web browsing framework for TypeScript.
Give an AI agent a browser. It clicks, types, navigates, and extracts data — autonomously completing tasks on any website. Built on Playwright with first-class support for OpenAI, Anthropic, and Google models.
Production-ready since v1.0. Contributions welcome.
Why Open Browser?
- Autonomous agents: Describe a task in natural language, and an AI agent navigates the web to complete it — clicking, typing, scrolling, and extracting data without manual scripting
- Multi-model support: Works with OpenAI, Anthropic, and Google out of the box via the Vercel AI SDK — swap models with a single flag
- Interactive REPL: Drop into a live browser session and issue commands interactively — great for debugging, prototyping, and exploration
- Sandboxed execution: Run agents in resource-limited environments with CPU/memory monitoring, timeouts, and domain restrictions
- Production-ready: Stall detection, cost tracking, session management, replay recording, and comprehensive error handling
- Open source: MIT licensed, fully extensible, bring your own API keys
Quick Start
# Install dependencies
bun install
# Set up your API keys
cp .env.example .env
# Edit .env with your API keys
# Run an agent
bun run open-browser run "Find the top story on Hacker News and summarize it"
# Or open a browser interactively
bun run open-browser interactiveArchitecture
Open Browser is a monorepo with three packages:
| Package | Description |
|---|---|
| `open-browser` | Core library — agent logic, browser control, DOM analysis, LLM integration |
| `@open-browser/cli` | Command-line interface for running agents and browser commands |
| `@open-browser/sandbox` | Sandboxed execution with resource limits and monitoring |
CLI Commands
Run an AI Agent
open-browser run [options]Describe what you want done. The agent figures out the rest.
# Search and extract information
open-browser run "Find the price of the MacBook Pro on apple.com"
# Fill out forms
open-browser run "Sign up for the newsletter on example.com with test@email.com"
# Multi-step workflows
open-browser run "Go to GitHub, find the open-browser repo, and star it"Don't lose this
Three weeks from now, you'll want Openbrowser again. Will you remember where to find it?
Save it to your library and the next time you need Openbrowser, it’s one tap away — from any AI app you use. Group it into a bench with the rest of the team for that kind of task and you can pull the whole stack at once.
⚡ Pro tip for geeks: add a-gnt 🤵🏻♂️ as a custom connector in Claude or a custom GPT in ChatGPT — one click and your library is right there in the chat. Or, if you’re in an editor, install the a-gnt MCP server and say “use my [bench name]” in Claude Code, Cursor, VS Code, or Windsurf.
