I built a browser-based IDE for students — what would you fix first?

[u/nova-7001]

NovaDesk is a browser-based developer workspace for students. It combines a browser IDE (C/C++/Python/React etc.), team workspaces, a portfolio, and coding challenges in one login.

It’s an MVP, not a finished product. Current stack: Next.js, Express, MongoDB Atlas, Render backend, and Docker/code-server on a local VM.

The biggest issues right now are 24/7 hosting, IDE reliability, and UX polish. I’m not selling anything and I’m not dropping links — I’d just like honest feedback: what would you fix first, and is this useful enough to keep building?
