HTTP Framework Benchmark Arena

An open benchmarking platform that measures HTTP, gRPC, and WebSocket framework performance under realistic workloads using io_uring-based load generation. Add your framework, get results automatically.

See which frameworks handle the most requests per second, ranked by throughput.

Compliance & Security

HTTP/1.1 compliance testing — RFC conformance, request smuggling vectors, and malformed input handling.

Set up and run the full benchmark suite on your own machine with Docker and gcannon.

Add a Framework

Add your framework with a Dockerfile and open a PR. Three steps to join the arena.

16 Test Profiles Across HTTP/1.1, HTTP/2, HTTP/3, gRPC and WebSocket

Every framework is tested under diverse, realistic workloads — from raw throughput to compression, gRPC unary calls, and WebSocket echo.

HTTP/1.1

Mixed GET/POST with keep-alive connections, query parsing, and chunked encoding.

GET/POST /baseline11

Short-lived Connection

Connections closed after 10 requests — measures TCP handshake overhead.

GET/POST /baseline11 (10 req/conn)

JSON Processing

Load dataset, compute derived fields, serialize ~10 KB JSON response.

Ingest a 20 MB binary payload and return its byte count.

Serve ~1 MB JSON with gzip compression. Bandwidth-adjusted scoring.

GET /compression (gzip)

Noisy (Resilience)

Valid requests mixed with malformed noise — bad paths, bad content-length, binary. Only 2xx count.

GET/POST /baseline11 + noise

Realistic mix of baseline, JSON, DB, upload, and compression requests with weighted scoring.

GET/POST mixed endpoints (100 req/conn)

Async Database (Postgres)

Async Postgres query over 100K rows — tests event loop scheduling, connection pooling, and async driver efficiency.

Pipelined (16x)

16 requests sent back-to-back per connection. Tests pipeline batching.

HTTP/2

Multiplexed HTTP/2 streams over TLS with 100 concurrent streams per connection.

GET /baseline2 (h2)

Round-robin across 20 pre-loaded static files — CSS, JS, HTML, fonts, images.

GET /static/* (h2)

HTTP/3

HTTP/3 over QUIC — measures framework performance with UDP-based transport.

GET /baseline2 (h3)

Multi-URI static file serving over QUIC with parallel streams.

GET /static/* (h3)

gRPC

Unary gRPC call over cleartext HTTP/2 — raw Protocol Buffers throughput without TLS overhead.

BenchmarkService/GetSum (h2c)

Same unary gRPC call over encrypted HTTP/2 with TLS 1.3.

BenchmarkService/GetSum (TLS)

WebSocket

WebSocket echo throughput — upgrade, send pipelined text messages, receive echoes. Measures frame processing performance.
