No, it wants to be your one stop shop:

No, Rome is a tool chain that is supposed to replace your separate tools for linting, building & testing.

So you might use it with your React app to get rid of eslint, webpack & jest (at some point, it's not there yet).

Svelte however is an entirely new framework which is fundamentally different from react/vue/angular in some very interesting ways (which I won't get in to here).
