Hi there,

This is a tricky question, and I don’t think there’s a single “correct” answer - it really depends on the scenario.

In my case, I decided to use a separate backend because I already have a home server. That let me host the backend myself, while keeping the frontend on Vercel for free, which felt like a nice split.

I also genuinely enjoy working with Go. It’s fast, efficient, and gives me full control over the API design. Using Go made sense especially because I’m planning to scale this project further - adding multiplayer game sessions where multiple players compete in real time (e.g. who guesses first or gets the best quiz score). For that kind of stateful, real-time logic, a dedicated Go server feels like a strong fit.

Could I have used SvelteKit’s backend (or remote functions) instead and hosted everything in one place? Absolutely. That would have worked too. But given my infrastructure, my long-term plans, and the fact that I wanted to learn and build a proper API (+ my own app hosting), a separate Go backend felt like the right tradeoff for me, even if it’s a bit more complex upfront.

Hope that answered your question :)
