Install: brew install autocannon

About:
Autocannon is a multi-threaded HTTP benchmarking tool capable of generating significant load with minimal configuration. It simulates real-world traffic patterns to measure server throughput, latency, and error rates. The tool provides real-time statistics and a comprehensive summary report upon completion.

Key Features:

Multi-threaded architecture for high concurrency
Zero-config defaults with extensive CLI options
Real-time statistics and histogram output
Supports HTTP/1.1 with pipelining
Node.js based for easy installation and cross-platform use

Use Cases:

Load testing APIs and web servers before production deployment
Comparing performance between different application versions or infrastructure changes
Identifying bottlenecks under sustained high traffic

Alternatives:

wrk – wrk is often faster but requires compilation and lacks built-in Node.js ecosystem integration.
ab (ApacheBench) – ab is a classic tool but less efficient and capable of high concurrency compared to autocannon.
k6 – k6 offers advanced scripting and scenarios but has a steeper learning curve and heavier runtime.
