BrowserOS - Open-Source AI Browser for Agents
BrowserOS is an open-source Chromium fork with a built-in AI agent. BrowserClaw gives your AI agents control of a real browser signed into your accounts. AGPL-3.0, 12K+ stars.
TL;DR
TL;DR: BrowserOS is a local-first, open-source Chromium browser with built-in AI for humans; BrowserClaw gives AI agents (Claude Code, Codex, Cursor) real browser control — solving the “AI can’t press the buttons” problem.
What Is BrowserOS?
BrowserOS is an open-source Chromium fork with two products in one codebase:
- BrowserOS — the AI browser for humans, a privacy-first alternative to ChatGPT Atlas, Perplexity Comet, and Dia
- BrowserClaw — the browser for AI agents, letting tools like Claude Code, Codex, and Cursor drive a real browser using accounts you’re already signed into
Both are free, open-source, local-only, and require you to bring your own AI keys. The project is AGPL-3.0 licensed and has 12,416 GitHub stars as of July 2026.
Why This Matters
AI assistants are powerful, but they hit a wall when a task requires clicking a button, filling a form, or accessing a logged-in account. BrowserClaw solves this by giving your AI agent its own Chromium instance it can actually control.
Setup Workflow
Step 1: Install BrowserClaw
Download from the official site for your platform:
- macOS: BrowserClaw.dmg
- Windows: BrowserClaw_installer.exe
Install like any browser, then sign into the sites you use daily.
Step 2: Connect Your AI
BrowserClaw ships with one-click setup for seven AI tools:
- Claude Code
- Codex
- Cursor
- VS Code
- Zed
- OpenCode
- Antigravity
For anything else that speaks MCP, connect with a URL endpoint.
Step 3: Give Your Agent a Real Task
In your AI chat:
“Find a good time next week for a 30-minute team meeting and send the invite.”
BrowserClaw opens its own tab, navigates to your calendar, and does the work while you watch live. Every session is saved as a replayable video.
Key Features
Live Dashboard
BrowserClaw’s new tab shows every active agent session — which site it’s on, what it’s doing, and how far along. You can monitor multiple agents simultaneously.
Session Replay
Every session is saved as a scrubbable video on your local disk, complete with a step-by-step action timeline. Rewind and inspect exactly what the agent did.
Privacy-First Architecture
All browsing runs locally. No data leaves your machine. You bring your own AI API keys. The default branch is main and the project is actively maintained (last push: July 20, 2026).
System Requirements
| Component | Requirement | |---|---| | OS | macOS, Windows, Linux (AppImage), Debian | | AI integration | MCP-compatible client | | AI keys | User-provided (no built-in billing) | | License | AGPL-3.0 |

FAQ
Q: What is the difference between BrowserOS and BrowserClaw? A: BrowserOS is an AI-powered browser for humans (like a privacy-focused alternative to AI browsers such as ChatGPT Atlas). BrowserClaw is the same codebase configured for AI agents — giving tools like Claude Code control of a real Chromium browser signed into your accounts.
Q: Does BrowserOS use my own AI API keys? A: Yes. You bring your own keys. BrowserOS does not include built-in AI billing or a hosted model.
Q: Is all browsing local? A: Yes. All sessions run locally on your machine. The project is open-source and the data stays on-disk.
Q: Which AI tools can connect to BrowserClaw? A: BrowserClaw ships with one-click MCP setup for Claude Code, Codex, Cursor, VS Code, Zed, OpenCode, and Antigravity. Any MCP-compatible client can connect via URL.
Q: What license is BrowserOS released under? A: AGPL-3.0.
Conclusion
BrowserOS solves a real gap in the AI agent ecosystem: the inability to interact with the live web through a real browser session. BrowserClaw turns any MCP-compatible AI tool into a browser-capable agent, with full live monitoring and session replay. It’s actively maintained, fully open-source, and runs entirely locally — no data leaves your machine.
If you run AI coding agents in your workflow, BrowserClaw is worth adding to your stack.
