AI‑powered Chromium browser that runs agents locally, privacy‑first
A Chromium‑based browser that lets you run AI agents directly on your machine using your own API keys or local models, keeping data private while supporting extensions and MCP integration.
BrowserOS brings AI agents into a familiar Chromium browser, letting power users and developers run large language models directly on their machine. By using your own OpenAI, Anthropic, or local Ollama keys, all prompts and browsing history stay on‑device.
The browser imports Chrome data, supports the full range of Chrome extensions, and connects to AI providers or locally hosted models. An optional MCP server lets external tools such as claude-code or gemini-cli drive the browser for automated testing or data scraping. Upcoming features include a built‑in AI ad blocker.
Install the macOS dmg, Windows installer, AppImage, or Debian package, then configure your API key or local model. BrowserOS is released under AGPL‑3.0, with an active Discord and Slack community that welcomes contributions and feature ideas.
When teams consider BrowserOS, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Automate repetitive web tasks
AI agents fill forms, navigate sites, and extract data, freeing users from manual clicks.
Secure AI‑driven research
Run local LLMs to summarize articles while keeping browsing history on the device.
Integrate browser into development pipelines
Control BrowserOS via MCP from claude‑code to test UI flows programmatically.
Extend existing Chrome extensions with AI
Leverage familiar extensions while adding agentic capabilities without rewriting code.
You need internet to access web pages and to call remote AI services; local models via Ollama can run offline after they are downloaded.
OpenAI, Anthropic, and any local model accessible through Ollama or LMStudio.
No. All data stays on your device unless you explicitly send it to a remote API.
Yes. BrowserOS uses the same Chromium extension framework, so most extensions work out of the box.
macOS, Windows, and Linux (AppImage and Debian packages).
