Nanobrowser is an open-source Chrome extension that provides AI-powered web automation through a multi-agent system (Planner, Navigator, etc.) running locally in the browser. Users supply their own LLM API keys (OpenAI, Anthropic, Gemini, Ollama, Groq, and OpenAI-compatible providers), making it a free alternative to OpenAI Operator.
Use cases
- automate repetitive tasks across websites with an ai agent
- free alternative to openai operator for browser automation
- run multi-agent web workflows with my own llm api key
- have an ai fill forms and navigate websites for me
- automate web tasks locally without sending data to the cloud
- use claude or gemini to control my browser
- scrape and summarize web pages with an ai agent
When to choose
- you want a free, open-source browser agent and already have LLM API keys
- privacy matters - automation runs locally in your Chrome browser
- you want to pick different models for different agent roles
- you need a Chrome Web Store-installable alternative to OpenAI Operator
When to avoid
- you need automation in browsers other than Chrome/Chromium
- you want a fully hosted solution with no API key setup
- you need headless or server-side browser automation rather than in-browser
- your workflow requires providers not yet supported
