Compare RPC providers on measured data

The top 4 on the chosen chain are compared by default. Pick your own — up to 4 — and the selection moves into the URL, so a comparison can be sent to someone else and they will see exactly what you saw.

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.

TenderlyvsBlast API

+11.3points

  • Latency+11.4
  • Head freshness0.1
  • Availability0.0
  • Correctness+0.0

The parts add to +11.3, exactly — the score is a weighted sum, so it comes apart.

+33.8points

  • Latency+26.8
  • Availability+6.0
  • Correctness+0.5
  • Head freshness+0.5

The parts add to +33.8, exactly — the score is a weighted sum, so it comes apart.

TenderlyvsCloudflare

+41.5points

  • Availability+29.7
  • Head freshness*+9.4
  • Latency+4.7
  • Correctness2.2

The parts add to +41.5, 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.
