About this benchmark

Pure static server component — zero data fetching, zero client JS

What is rari?

rari is a React Server Components framework running on a Rust runtime. The HTTP server, RSC renderer, and router are written in Rust with an embedded V8 engine. You write standard React — the runtime underneath is Rust instead of Node.js.

Infrastructure

Server: AWS EC2 t3.micro (1 vCPU, 1 GB RAM)
Region: us-east-1 (Virginia)
Runtime: rari 0.11.0 (Rust binary, Node CLI wrapper)
Reverse Proxy: Caddy 2.11 (auto Let's Encrypt SSL)
Domain: virginia.uptimeclaw.com
Cost: $0/mo (free tier, 12 months)

Architecture

Browser → Caddy (SSL termination, port 443)

→ rari Rust binary (port 3000, localhost)

→ Embedded V8 (React RSC rendering)

→ Static assets served directly by Rust

Note: A Node.js process acts as the CLI wrapper that launches the Rust binary. The Rust binary handles all HTTP requests — Node.js is not in the request path.
