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
+20.7points
- Latency+20.9
- Head freshness−0.1
- Availability−0.0
- Correctness+0.0
The parts add to +20.7, exactly — the score is a weighted sum, so it comes apart.
TenderlyvsMerkle
+29.3points
- Latency+29.3
- Availability−0.0
- Head freshness+0.0
- Correctness+0.0
The parts add to +29.3, exactly — the score is a weighted sum, so it comes apart.
Tenderlyvs1RPC
+99.4points
- Availability+40.0
- Latency*+30.0
- Correctness*+20.0
- Head freshness*+9.4
The parts add to +99.4, 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.
