Is this like ReasonML and its React-Reason framework?
I don't really understand how it works, what part is Rust powered, is it reimplementing the JS engine in Rust?

The Rust part is the server runtime. Instead of Node.js running your React Server Components, rari uses a Rust server with an embedded V8 engine. Same React code, different server underneath.
You write React → Rust server executes it → better performance than Node-based alternatives.
While we use Deno's excellent crates (deno_core for V8 bindings, we're big fans of the project!), you're not locked into the Deno ecosystem. rari uses standard node_modules resolution, so your existing Node/npm workflows just work. Think of it like this: Deno gives you a runtime to build on, while rari gives you the full stack with integrated bundler, router, HMR, and dev server all configured to work together for RSC apps.
it would be interesting to see a performance comparison to node and bun
