What is Browseros?
BrowserOS is an open-source, Chromium-based agentic browser that runs AI agents locally on your computer, offering a privacy-first alternative to Chrome, ChatGPT Atlas, and Perplexity Comet. It lets you describe web tasks in plain language, and the browser handles clicking, typing, and navigating automatically. Built for the AI era, it combines familiar Chrome compatibility with integrated AI automation capabilities.
Key features include three AI modes: Chat Mode for asking questions about pages, Agent Mode for executing multi-step tasks like form filling and data extraction, and Graph Mode for building visual workflows (coming soon). It supports 13+ AI providers including Anthropic Claude, OpenAI, Google Gemini (with free tier), Moonshot Kimi, OpenRouter with 500+ models, and local models via Ollama and LM Studio. The browser includes 53 built-in browser automation tools and 40+ app integrations via MCP servers for Gmail, Calendar, Docs, Sheets, and Notion.
BrowserOS is designed for founders, developers, researchers, and anyone who wants to automate repetitive web tasks without coding. It's fully open source under AGPL-3.0 license, backed by Y Combinator, with 10,000+ GitHub stars. Users bring their own API keys or use free tiers, keeping browsing data and API keys under complete user control with no third-party data sharing.
The browser works on macOS, Windows, and Linux with system requirements matching Chrome or Safari. You can import Chrome bookmarks, passwords, history, and extensions in one click. All Chrome extensions work seamlessly since BrowserOS is a Chromium fork. It integrates with Claude Code, Codex, and Gemini CLI for developer workflows.

Which AI model should I use for Agent Mode?
For Agent Mode, use Claude Opus 4.5 for best results. Claude Sonnet 4.5 offers great quality at medium speed, while Claude Haiku 4.5 and Gemini Flash are faster but with good rather than best quality. Local LLMs are not yet powerful enough for Agent Mode as the model needs strong reasoning to click the right elements and handle multi-step tasks.
