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

Ubersuggest

  • Plans 2 and 3 both cost $99/month despite different feature limits
  • Enterprise and custom plans available but pricing not published
  • 7-day free trial requires entering payment information first
