Kuba Rogut, a full-stack software engineer, participated in Daytona's Hacksprint, where he developed an innovative autonomous A/B testing platform named A/B GPT. This platform leverages Daytona's isolated development environments, Browser Use's real-time web navigation, and Claude Code's autonomous coding capabilities to simulate user behavior, identify issues, and implement improvements in web applications without manual intervention. During the hackathon, Rogut focused on a simple e-commerce website to demonstrate the platform's potential by addressing a lack of product filtering options. By using Browser Use agents to simulate user interactions and Claude Code to deploy changes in real-time, the system automates the A/B testing process, identifying and resolving user experience issues. This approach earned Rogut first place and the Best Use of Browser Use award at the event, highlighting the potential of combining AI tools for innovative problem-solving in software development.
