How this comparison was built

Scores are medians across 1 audited CookieBAR sites and 286 audited Modernizr sites in the BeaverCheck database.

Small sample: one or both technologies have fewer than 10 audited sites. Treat these numbers as directional — medians stabilize around 20–30 audits per side.
