Compare CodSpeed and gtmetrix.com free tiers side by side. Pricing, limits, change history, and risk assessment for developers.
CodSpeed offers a free tier ("Free"). We are not publishing a free-tier verdict for gtmetrix.com. When we last read the page we cite for gtmetrix.com, on 2026-10-28, we found a change we could not reconcile with the terms we publish for it. We are not comparing the two pricing histories.
A verdict here is not a fixed property of the vendor. A one-off pricing event demotes a vendor while its recorded date falls in the last 180 days and then lapses on its own, with nothing about the vendor having changed; a standing condition — a free tier withdrawn and not restored, a product retired — does not lapse with time. A badge carrying a date states the record it rests on; a badge with no date rests on no record in force.
