Vibe Coding Benchmarks exists because nobody was measuring the part that matters.
There are plenty of comparisons of AI code generation quality. Which platform produces cleaner React components. Which one handles edge cases better. Which one writes more idiomatic TypeScript. That's useful information, but it answers the wrong question.
The question that matters is: what happens when real users show up? When your app gets 200 concurrent requests. When someone visits for the first time and the server hasn't been warm for 15 minutes. When 50 users hit the database at the same time. When you need WebSockets, email, a CDN, and the ability to not crash on a Tuesday afternoon.
We run standardized infrastructure tests across the major vibe coding platforms and publish the results. No spin, no affiliate deals, no "sponsored content" labels on pages that are actually ads. The data is the data. If a platform fails at 200 concurrent users, we say so. If it handles 1,000, we say that too.
Built by engineers who've been on the other side of the "it works in the demo" conversation. We've deployed production apps, debugged 3am incidents, and sat in meetings where someone asked "why is the site slow?" and the answer was "because the infrastructure was never designed for this."
This site runs on OpenKBS infrastructure — AWS Lambda, CloudFront, Neon Postgres. OpenKBS is also one of the platforms we benchmark. We disclose this because you should know, and because our methodology is public precisely so you can verify we're not cooking the numbers.
