+## Performance Plans
+
+Simulate cloud plan resource constraints for testing. **Performance plans are SQLite-only** (like cloud n8n):
+
+```bash
+# CLI usage
+pnpm stack --plan trial        # 0.375GB RAM, 0.2 CPU cores
+pnpm stack --plan starter      # 0.375GB RAM, 0.2 CPU cores
+pnpm stack --plan pro-1       # 0.625GB RAM, 0.5 CPU cores
+pnpm stack --plan pro-2       # 1.25GB RAM, 0.75 CPU cores
+pnpm stack --plan enterprise  # 4GB RAM, 1.0 CPU cores
+```
+
+**Common Cloud Plan Quotas:**
+- **Trial/Starter**: 0.375GB RAM, 0.2 CPU cores
+- **Pro-1**: 0.625GB RAM, 0.5 CPU cores
+- **Pro-2**: 1.25GB RAM, 0.75 CPU cores
+- **Enterprise**: 4GB RAM, 1.0 CPU cores
+
+Resource quotas are applied using Docker's `--memory` and `--cpus` flags for realistic cloud simulation.

+✅ No worker containers: Only cloud containers are created
+✅ Guaranteed cloud testing: Tests must have @cloud:* tags or they fail
+✅ Complete fixture chain: Full n8n/api/context/page fixtures available
+✅ Fresh containers: Each test gets its own cloud container with resource limits
+✅ Clean database state: Per-test database reset with enhanced timing
+✅ Resource isolation: True cloud plan simulation without interference
+
+Usage:
+
+// Import the cloud-only fixture instead of base
+import { test, expect } from '../../fixtures/cloud-only';
+
+test('Performance test @cloud:trial', async ({ n8n, api }) => {
+  // This test runs ONLY on a trial plan container (768MB, 200 millicore)
+  // No worker containers are created
+});
+
+Flow:
+1. Detect @cloud:* tag (required)
+2. Create cloud container with resource limits
+3. Wait 5s + database reset with retries
+4. Provide complete n8n/api fixture chain
+5. Run test against cloud container only
+6. Clean up cloud container
+
+Perfect for: Performance testing, resource constraint testing, cloud plan validation
