9 providers scored against each other.

Where the gap comes from

Two scores side by side say one is higher. This says why: the score is a weighted sum, so it comes apart, and each component’s share of the difference adds back to the difference exactly. Compared against Tenderly, the highest scorer of those selected.

TenderlyvsCloudflare

+51.0points

  • Availability+29.7
  • Latency+14.1
  • Head freshness*+9.4
  • Correctness2.2

The parts add to +51.0, exactly — the score is a weighted sum, so it comes apart. Components marked * were measured for only one of the two; the other’s weight is spread across what it does have, which is why the two sides can carry different weights for the same row.
