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

MarketMuse

  • The free plan caps at 10 queries per month and excludes tracked topics and content briefs, limiting it to light exploration only.
  • Content brief types beyond the Article format are restricted to the top Strategy tier.
  • Pricing amounts are not published on the site, so buyers must request a quote to compare costs against competitors.
