Why it's listed

sitespeed.io is listed in seo & web performance because it competes on utility: open web-performance monitoring & auditing. It's community-maintained open source: the incentive is the tool itself. Licensed MIT; pricing: free. Technically it's lean — it runs comfortably on modest hardware, which is exactly the proof-of-work efficiency we rank for. This entry is provisional — the scores are seeded estimates pending our full manual rubric pass, and the verification date will appear here once complete.
