PeekAPI – Lightweight API analytics with minimal setup

Summary: PeekAPI provides instant analytics for REST APIs by adding a single middleware, offering real-time insights into traffic, errors, latency, and consumers. It supports eight programming languages with zero-dependency SDKs and includes a free tier of 500K events per month.

What it does

PeekAPI integrates via one middleware to monitor API traffic, errors, latency, and usage across Node.js, Python, Go, Ruby, Rust, PHP, Java, and Dart. It requires no agents or configuration files.

Who it's for

Developers seeking lightweight, cross-language API analytics without complex setup or heavy dependencies.

Why it matters

It addresses the lack of visibility into API performance and consumers without the overhead of full APM platforms or extensive configuration.
