Utkarsh Karki enhanced the browser-use/browser-use repository by developing features focused on improving reliability and compatibility for automated browser actions. He implemented default handling for ScrollAction.down, allowing the system to gracefully manage missing fields in LLM responses and maintain expected scroll behavior. Using Python and leveraging his expertise in API development and data validation, Utkarsh also made the max_ws_frame_size parameter optional to support older CDP versions, and refactored CDP client initialization to streamline setup for large DOMs. These changes reduced validation errors and improved cross-model compatibility, particularly with AWS Bedrock Claude and Gemini, demonstrating thoughtful backend engineering.
November 2025 performance for browser-use/browser-use focused on reliability and cross-model compatibility enhancements for ScrollAction handling and CDP integration. Implemented default handling for ScrollAction.down, making the field optional in LLM responses to prevent validation errors and preserve expected scroll-down behavior; added optional max_ws_frame_size to improve CDP compatibility with older cdp-use versions; simplified CDP client initialization by removing legacy compatibility fallback to streamline setup for large DOMs. These changes reduced model- and version-related errors, improved automation reliability, and set the stage for smoother operation across diverse LLMs and browser workloads, delivering faster startup and more predictable behavior with models such as AWS Bedrock Claude and Gemini.
