Fortio

Fortio is an open source load testing library, command-line tool, and server application written in Go. Originated as Istio's performance characterization tool (in particular proxy overhead), Fortio has evolved into a versatile tool for load testing and performance benchmarking of HTTP, gRPC, and TCP services. Among other options it enables users to generate a specified query-per-second (QPS) load and records detailed latency histograms, facilitating the analysis of performance metrics. The server component offers a straightforward web UI and REST API, allowing users to initiate tests and visualize results through graphical representations. Beyond load testing, Fortio provides server-side features akin to httpbin, including request echoing with headers, configurable latency or error responses, TCP echoing and proxying, HTTP fan-out, and support for gRPC echo and health checks. These capabilities make Fortio a versatile tool for debugging and testing high-performance services in cloud-native environments. As an organization set of git repositories, is also a growing set of reusable libraries for writing Cloud Native Go code and CLIs.
