BrowserKing: Open-Source Chrome Extension for Browser Control via Claude and Other Models
BrowserKing is a free, open-source Chrome extension that turns Claude and other AI models into full browser agents. It operates from a side panel and requires no account or subscription—just your Anthropic API key.
Key Features
- Supports Claude and 15+ other AI models
- Takes screenshots of the current browser screen and sends them to the selected model
- Acts on the model's decisions to perform browser actions
- Each provider gets its own theme color, with the UI adapting visually when switching models
Browser Control Capabilities
- Clicking buttons
- Filling forms
- Scrolling
- Navigating tabs
The developer notes that Claude handles the vision + tool call combination particularly well compared to other providers tested. The extension is available on GitHub under the MIT license.
This type of tool is useful for automating browser-based tasks through natural language instructions, potentially reducing manual interaction with repetitive web interfaces.
