GitHub 5k+ Star open source project | AI-driven browser automation tool Nanobrowser

Nanobrowser's core features

• •  Multi-agent collaboration : Through the collaboration of three AI agents, Planner, Navigator, and Validator, task strategies can be adjusted dynamically like real people.
• •  Privacy and security : All operations are run on the local browser, and data does not need to be uploaded to the cloud, completely eliminating the risk of leakage.
• •  ? Multi-model support : Compatible with mainstream large models such as OpenAI, Anthropic, Gemini, DeepSeek, etc. Users can freely assign different models to optimize cost and performance.
• •  ? Intelligent error correction : When encountering unexpected situations such as verification codes and page changes, the strategy is automatically adjusted, and the task success rate is as high as over 90%.
• •  ? Completely free and open source : Based on the AGPL-3.0 protocol, the code is transparent and traceable, and it is the best alternative to OpenAI Operator.

Why you need Nanobrowser

• •  Operators : Automatically generate competitor reports and capture social media data, saving you from staying up late to copy and paste.
• •  Developers : Crawl GitHub trending projects and automate testing of web page interactions with one click.
• •  E-commerce parties : monitor commodity price fluctuations in real time and automatically grab limited-time discounts.

5-minute quick start guide

1. 1.  Download and install :

• • Download the latest version of the extension pack from GitHub  https://github.com/nanobrowser/nanobrowser/releases/tag/v0.1.4
• • Chrome browser opens chrome://extensions/, enable developer mode and load the unpacked extension folder.

• 2.  Configure the model key :
• • Click the toolbar icon to open the sidebar, add the DeepSeek API key in the settings, and assign models to different agents.
• 
  
• 3.  Execute the task :
• • Enter natural language instructions (such as “grab today’s popular Python projects on GitHub”), and the AI ​​agent will automatically parse and execute the complete process.
• 
  
• 
  
• 4.  Monitoring and adjustment :
• • View task status in real time through the interactive sidebar and make adjustment requests at any time (such as "exclude projects with less than 1000 stars").

Precautions

• •  Hardware requirements : A stable network environment is required. For some complex tasks, it is recommended to use high-performance models such as GPT-4.
• •  First time use : You need to authorize the browser to record, but all data will only be processed locally.
• •  Dynamic adjustment : If a task fails, you can intervene manually or let Planner automatically retry a new strategy.

Open Source and Future Development

Nanobrowser is completely open source, and developers can contribute code or customize exclusive features. Its team is planning to launch:

• •  Expanded model support : Integrate more large models such as Claude, Zhipu AI, etc.
• •  Security firewall : prevents malicious script injection and ensures the safety of automated operations.
• •  Session replay function : efficiently review historical tasks and optimize token consumption.
