📈 What if 10,000 users joined your app tomorrow?
More users should mean more opportunities, not a slower app or an overloaded backend.
Database indexing, efficient queries, caching, pagination, and proper backend architecture help applications handle growing traffic more reliably.
Scalability should be planned before growth becomes a problem, not after users start experiencing slowdowns.

Startfrom 2.0 is live. It's our template library: finished websites designed at Apollo Studio, available as a Framer project, an Astro theme or a Next.js app.
Each template page shows what you get and runs the live demo in the page. Some templates are free.
Keeping content separate from layout would make the Astro and Next.js versions easier to customise. Do they share a content schema, or does each template have its own setup?

What was the trickiest part of getting Yjs and the saved sessions to work together? I'm curious how you handled someone reconnecting after others had kept editing.
