NanoBrowser runs directly in your browser as a Chrome extension, enabling you to automate repetitive or complex web tasks via natural-language prompts. You configure it with your own LLM API key—OpenAI GPT, self-hosted LLaMA models, or others—and define workflows composed of multiple agents. It supports data scraping, form interactions, automated research, and workflow chaining through LangChain integration. You can orchestrate agents to collaborate on subtasks, export results in CSV or JSON, and debug or refine steps interactively. As an open-source alternative to proprietary operators, NanoBrowser prioritizes privacy, extensibility, and ease of use.
