See CodePerformance in action on real open-source projects.
Experience how CodePerformance identifies real performance bottlenecks — and tracks them to verified improvement — without connecting your own repository.
These demos are generated directly from popular open-source projects, exactly as they appear in Everdone.
Why we created these demos
Performance tools are hard to evaluate from claims or benchmarks alone.
So we reviewed well-known open-source repositories — frameworks, libraries, and tools your team already knows — using CodePerformance.
What you'll see:
This is exactly what CodePerformance produces when you run it on your own code.
