Fixing 503 Errors in Lovable Cloud

Getting 503 errors, "Error loading tables", or auth timeouts? Your instance might need an upgrade.

The Problem

You're seeing one or more of these:

  • 503 PGRST002 errors
  • "Error loading tables" in dashboard
  • Auth calls timing out
  • Dashboard stuck loading
  • Status 544 timeout errors

Your frontend loads but anything data/auth-related just dies.

Why This Happens

Your Lovable Cloud instance has outgrown its current resource limits. From the Lovable docs: this typically happens "if you have too much data running on a smaller Cloud project instance."

The default Tiny instance is meant for trying things out, not production traffic.

Instance Sizes

  • Tiny — Testing, MVPs
  • Mini — Early projects, few users
  • Small — Growing apps, moderate traffic
  • Medium — Production, regular use
  • Large — High demand, serious traffic

The Fix

  1. Go to Cloud tab in your project
  2. Click Overview → scroll to Advanced Settings
  3. Upgrade your instance size (Tiny → Mini, Small, Medium, or Large)
  4. Wait a few minutes for the upgrade to complete

That's it. Your app should start responding again.

⚠️Heads up

Important: Larger instances increase Cloud usage and costs. Check your billing before upgrading to Large.

Resource Alerts to Watch

Lovable monitors three metrics and alerts you when limits are approaching:

  • Disk space — Alert when less than 10% remains
  • IO budget — Alert at below 50% capacity
  • CPU load — Alert when usage exceeds 80%
💡Pro tip

Tip: If you see these alerts, upgrade before things break. It's easier to prevent downtime than to recover from it.

Still Not Working?

If upgrading doesn't fix it:

ℹ️Note

Note: If you're hitting these limits frequently, consider migrating to your own Supabase project for more control and predictable costs.
