Author here. We added proper app router support, SSR, and correct RSC semantics to Rari. The performance improvements were dramatic:
- 0.69ms avg response (3.8x faster than Next.js)
- 20,226 req/sec throughput (10.5x higher)
- 4ms P99 latency under load (12x faster)
- 68% smaller bundles (27.6 KB vs 85.9 KB)
The key insight: when your architecture aligns with React's design philosophy, performance follows naturally. Server components by default, 'use client' when needed, true SSR from the Rust runtime.

Try it: `npm create rari-app@latest`
Happy to answer questions about the architecture and how we achieved these numbers.
