Robyn is a High-Performance Web Framework with a Rust runtime

Composite rank

Each profile of a family is worth 100 to the entry that leads it, and the composite is the sum over the family, less 2.5% for each of routing, middleware, request and response the entry does not do for you - its completeness factor, which the WebSocket and gRPC families do not carry. The field is this entry's own league: engines and reverse proxies are scored apart from frameworks. How it works.

Family	Rank	Composite

Every result

Alpha Round, 7 runs. Requests per second is the best of three; latency, CPU and memory come from that run.
