Tapr – Debug API performance instantly from your terminal

Summary: Tapr identifies API performance bottlenecks by measuring DNS, TCP, TLS, and server processing times with millisecond precision. It provides P50/P95/P99 latency metrics, supports batch testing, and exports results in JSON or CSV formats for CI/CD integration.

What it does

Tapr traces API requests to reveal detailed timing breakdowns and success rates, enabling concurrent endpoint testing and real-time monitoring directly in the terminal. It operates as a single binary with zero configuration and works offline.

Who it's for

Developers and DevOps teams needing precise API health diagnostics and automated performance checks within CI/CD pipelines.

Why it matters

It eliminates guesswork by pinpointing exact sources of API latency, facilitating faster debugging and reliable automation of health checks.
