VIII. Plugin Impact (Paid)

Question: Which plugin is slowing down my site?

Runtime impact analysis for WordPress plugins. No more disable-test-enable cycles — see exactly which plugin causes warnings, fatals, slow hooks, and memory pressure.

This is the dashboard that sells Logystera. Screenshot it for the homepage.

Why this matters

Typical WordPress debugging:

1. Site is slow
2. Disable plugin A → test → still slow
3. Enable plugin A, disable plugin B → test
4. Repeat 20 times
5. Give up

Logystera approach:

1. Open Plugin Impact dashboard
2. See: elementor-pro → 847 warnings, 12ms hook overhead
3. Done
