Install: brew install apib

About:
APIB is a command-line HTTP performance-testing tool designed for load testing and benchmarking web services. It generates high volumes of concurrent requests to measure server throughput, latency, and stability under stress. The tool provides detailed performance metrics and is optimized for testing APIs and web servers.

Key Features:

High-performance multi-threaded request engine
Detailed latency and throughput metrics reporting
Support for HTTP/1.1 and HTTP/2 protocols
Configurable request patterns and concurrency levels
SSL/TLS support via OpenSSL

Use Cases:

Load testing REST APIs to determine maximum throughput
Benchmarking web server performance under concurrent connections
Stress testing production endpoints before deployment
Comparing performance across different server configurations

Alternatives:

wrk – wrk uses a different threading model and Lua scripting, while APIB focuses on HTTP/2 support and detailed metrics
ab (ApacheBench) – ab is simpler but limited to HTTP/1.1, whereas APIB supports modern protocols and more detailed reporting
hey – hey is written in Go and offers similar functionality, but APIB provides more granular control over connection parameters
