A fast HTTP/1.1 benchmarking and load-testing tool written in Node.js, inspired by wrk and wrk2. It can be used from the command line or programmatically via its API, supporting HTTP pipelining, HTTPS, and worker threads.

Use cases

• load test an HTTP API before production
• benchmark my web server's requests per second
• compare performance of Node.js frameworks
• stress test an endpoint with concurrent connections
• run HTTP benchmarks in CI
• measure latency percentiles for an HTTP service

When to choose

• you need a fast, scriptable HTTP benchmarking tool in Node.js
• you want to generate more load than wrk or ab
• you need programmatic load testing via a JavaScript API
• you want HTTP pipelining or HTTPS support in benchmarks

When to avoid

• you need HTTP/2 or gRPC load testing
• you need a distributed load-testing setup across multiple machines
• you are benchmarking non-HTTP protocols
