Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Lighthouse

  • Performance scores vary significantly due to A/B testing, device differences, browser extensions, and antivirus software affecting results
  • Limited to metrics that contribute to scores; Opportunities and Diagnostics don't directly impact scoring
  • Diminishing returns above 0.96 score, making perfect 100 scores extremely challenging
  • Scores based on HTTP Archive data which may not reflect all performance scenarios

Surfer SEO

  • Entry Discovery plan at $49 per month limits users to a single seat and 120 documents
  • AI prompt tracking is excluded on the Discovery plan and capped at 25 prompts weekly on Standard, 50 daily on Pro
  • Unlimited documents on the Peace of Mind plan are subject to a fair usage policy rather than being truly unlimited
