6 tools · sorted by API Performance
Ranked by speed benchmarks and Time to First Byte from independent tests.
We scored 6 headless cms tools ranked specifically by api performance — cdn delivery, caching, and query speed.. Contentful comes out on top at 90/100, Contentful edges out Sanity by a narrow margin, so it's worth comparing both closely against your specific requirements. As with every list on RadarTrek, the ranking reflects our independent scoring methodology, not advertising — use the dimension scores below to check whether the top pick actually fits your specific situation, since "best for best performance" rarely means best for every use case within that category.

Based on our independent scoring, Contentful ranks highest for best performance at 90/100 on api performance. Sanity is the closest alternative, followed by Payload CMS. See the full ranked list above for the complete breakdown across every scored dimension.
Contentful currently ranks above Sanity for best performance in our scoring. For a full side-by-side breakdown across every dimension, not just this one use case, visit the head-to-head comparison page for these two tools — it's the more reliable way to decide between them than this ranking alone.
We review category rankings whenever a tool's underlying dimension scores change meaningfully, when a new tool enters the category, or when a tool is deprecated or acquired. The ranking reflects current scores, not a one-time snapshot — check the methodology note below for what specifically feeds into the api performance score driving this list.
No — rankings are generated purely from our independent dimension scores, the same scores used across every tool review and comparison page on RadarTrek. Some listed tools have affiliate links, which may earn us a commission if you sign up, but commission has no influence on score or rank order.
