Earlier quoted context omitted.

You're right about the messaging being confusing, I've been writing everything solo, so I'm definitely open to PRs that help with the copy. To clarify: "Rust-powered" refers to the server runtime itself, not just the bundler. The actual HTTP server, RSC renderer, and routing are all written in Rust (using an embedded V8 engine to execute your React components). It's not just Rolldown doing the bundling. On the npm in…

Yeah I wrote my comment initially thinking it was just rolldown being used, so the "rust-powered" was confusing, I think the tagline is actually ok now that I know this, but really you're doing two things here 1/ an alternative framework for RSCs similar to nextjs, tanstack or react router 2/ a rust runtime for javascript, similar to node, deno or bun (except maybe not as general purpose)

Exactly! Those are the two main layers.

The runtime piece is definitely less general-purpose than Node/Deno/Bun. It's optimized specifically for React Server Components with things like streaming, Suspense boundary handling, and server action execution baked in. You wouldn't use it to run arbitrary JS apps.

this looks neat and reminds me of "Ferrari" for fast and combines "react" so it's a great name. Was there a specific use case for this that inspired you? I would imagine some massive existing heavy thing that you plugged in to fix to save it? I just put my open source thing out so it's nice to see some traction on yours, rooting for you.

Thank you, that's very kind! The name actually comes from "Runtime Accelerated Rendering Infrastructure" (RARI), but I love the Ferrari connection, it definitely fits the performance theme.

The inspiration was pretty straightforward: I wanted to build something for myself that was as performant as I could make it. I'd been using Rust a lot more in my day-to-day work and wanted to see if I could bring those performance benefits to React development without forcing JS devs to write Rust. The goal was to abstract away the complexity of Rust but still deliver the same benefits.

Congrats on shipping your project! What did you build?

ah gotcha... i was picturing like this massive web page that was dog slow that you just like made mad fast... but that's cool though. I'll run it.

I built autonomo on github, it's this mcp you plugin to your whatever ai editor and it drives the app/web/desktop whatever thing and validates it actually runs and works... keep building homie!

It's like beating a dead horse. React is the literal worst of all the modern JavaScript frameworks and yet that's what everybody insists on using. Vue is light years ahead of it (and will be even further ahead when the new Vapor mode is released in 3.6). Svelte is ahead. Solid is ahead. Heck, even Marko is ahead.

I am a react developer. For past few months I am working in vue and I Just dont see any benefits

I hate React, but Vue never seemed much better. What is better about it, in your opinion?

Reacts added some poor abstractions over the last decade. Looking at you hooks and effects.

But its far from the worst.

It was the first framework to put together JSX, a functional way of defining components and simplifying state. This was a monumental improvement. As a result they earned mass adoption.

As a result its the framework that now has a community moat that is not going to crumble until someone else can break ground in the way they did.

Sure, some of these could be considered "better" but they're all better due to incremental improvements for Frontend Engineering.

None of which are substantial enough to unseat the king

That's rather amusing. "Am I wrong? No it's the rest of the world!"

How are these other frameworks so far ahead? I've used a couple of frameworks and React has been the easiest from the big ones to wrap my head around.

ok so I actually like this, but the description and documentation in general are terrible "rust-powered" meaning it uses rolldown to bundle the javascript, that's fine, but it's a weird thing to highlight, it's confusing for people that aren't super familiar with vite and might think this is a rust framework from the docs "one of rari's superpowers is seamless NPM package integration" this makes me think the docs are…
