Litro
Benchmarks
Real-world performance numbers for Litro and competing frameworks, measured on the same hardware with identical page content.
Framework Comparison
Identical minimal apps (2 routes, same content) built in SSG mode. Litro uses Lit + Nitro, Nuxt uses Vue + Nitro, Next.js uses React.

Lighthouse Performance (SSG)
SSR pages use Declarative Shadow DOM — Lighthouse cannot measure paint events inside shadow roots, so only SSG scores are shown.

SSR Streaming
Streaming metrics are SSR-only. TTFB is time to first byte of the response; TTLB is time to last byte. Delta is how long the stream took to deliver the full payload.
