autocannon
One-command HTTP benchmarking for a quick answer about a single endpoint.
What it is
autocannon is a Node.js HTTP/1.1 benchmarking tool that produces latency percentiles and throughput for a single endpoint from one command line. It is not a scenario tool and makes no attempt to be; it answers 'how fast is this route' in about ten seconds.
Best for
Where it is strong
- Zero configuration; useful output in seconds.
- Good percentile reporting for such a small tool.
- Scriptable from Node for micro-benchmarks in CI.
Where it falls short
- Single endpoint only — no user journeys, no correlation, no think time.
- No distributed execution.
- HTTP/1.1 focused.
