Every free cdn tier that clears our bar in 2026: 6 offers meet the criteria and 14 offers are demoted with a named reason. Recorded changes and a published ranking method. We could not confirm today's terms for 13 of them: on 12 the page we cite did not answer, and on 1 our own read did not confirm them. Each row says why.

We publish no ranking of these. Nothing we record measures popularity or generosity, so naming a best or a top few would be our preference rather than our data. We hold 6 free cdn offers that clear our bar, each listed with the terms we publish and the date we last read them. Our ranking rule is published at /criteria.
6 offers meet our criteria for this category. Of those, 5 carry no recorded change to the terms we publish, and we publish no durability signal for 1. The Durability column below says which offer is in which group, and links the dated record behind every change. We withhold the class where the pricing page does not resolve or states no amount, tier or rate we can read, where we refused the last read, where the listing is gated, or where a narrowing in our records cites no source or no archived copy of the vendor's page has confirmed it. We do not rank these by how much you get, because the limits are not comparable without reading each vendor's page.
