Which Node.js versions are available?

Latest : Node.js 26. Recommended : Node.js 24 (LTS stable). Set via VERSION=latest or VERSION=recommended .

How does the automatic V8 heap tuning work?

Apps with 1 GB+ RAM get automatic V8 tuning to avoid memory crashes on heavy workloads. Smaller apps use Node's default heap.

Do I need to build before uploading?

No. Square detects missing node_modules and runs npm install before start. Accepts projects using npm, pnpm, or yarn.

Can I customize the start command?

Yes. Set START= in squarecloud.app with whatever command you prefer. Useful for passing modern Node flags like --env-file=.env.extra (loads vars without our env system), --watch , --inspect , or --max-old-space-size for specific workloads.
