Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.

Free real-time analytics for open source projects on GitHub
Explore over ten billion GitHub events covering stars, commits, pull requests, issues and reviews, updated as new public events arrive.
Follow star-based rankings for hot repositories and browse editorial collections that map trends across languages, topics and technical fields.
Query the underlying event tables directly with SQL, or pull the same numbers into your own tooling through the public API.
Dedicated views track AI agent frameworks, LLM tooling and MCP servers, making it easy to compare a crowded and fast-changing space.
