Fixing 503 Errors in Lovable Cloud

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.

⚠️ 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%

💡 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:

• Check status.lovable.dev for outages
• Contact support@lovable.dev
• Could be a different issue (quota limits, actual outage, etc.)

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