I love the hands-on developer experience of programming in Svelte. But since we're in October of 2026 I have to ask, is the vibe-coding experience in Svelte any different than in React? Can anyone with experience in both comment?
I’ve used both in vibe coded side projects, so the caveat is that it’s entirely personal use.
Opus 4.8+ did fine with SvelteKit and I didn’t notice much difference with token usage vs. React.
I will say that I have heavily prompted my agents to read current docs for all libraries, whether in their training set or not. So my agents read React docs even if their training set is full of React code.
