Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.
Startups.RIP is a research library of 2,200+ startup stories — including many Y Combinator companies — that documents what each one built, how it ended, and how you could rebuild it today. Free accounts browse research reports and build plans; Pro adds implementation-ready technical specs and a CLI that imports the research into coding agents like Claude and Codex.

Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.
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.

A searchable library of over 2,234 startup reports with status labels such as Acquired, Inactive and Active, organised by YC batch and industry.
Each featured company comes with practical build plans and prototypes that turn the historical lesson into a concrete project you can start.
Pro members unlock implementation-ready specifications that describe how to actually build the product, not just what the original team did.
Ask questions about any report or build plan and get answers drawn from the archive, rather than reading every page manually.
