Simon Willison's recent blog post discusses the creation of a SQLite database from Mozilla's browser compatibility data, which is now available for download and exploration via GitHub. He details the process of converting the data and hosting it with open CORS headers for accessibility.
The key insight here for someone tracking Claude Code, Codex, and AI development tools is the practical application of AI-assisted programming. Simon Willison utilized Codex Desktop (GPT-5.5) to automate the creation of a GitHub Actions workflow, demonstrating a seamless integration of AI into the development lifecycle to efficiently manage and deploy a browser compatibility database. This showcases the potential of AI tools in streamlining dev operations and enhancing productivity.
