Fortio
Fortio is a free, open-source Go project for HTTP and gRPC load testing. It combines a load-testing library, command-line tool, echo server, and web interface, with API, Linux, macOS, self-hosted, web, and Windows platforms. A run can target a specified queries-per-second rate or maximum speed, and can stop after a duration, a fixed call count, or interruption. Fortio records latency histograms and percentiles such as p99. Its server offers a web UI and REST API for starting tests and viewing latency and comparison graphs. Additional server functions include request echo, probabilistic latency or error injection, TCP echo and proxy, HTTP fan-out proxy, and gRPC echo and health. Go applications can embed Fortio or use its log, stats, and fhttp components separately. Fortiotel adds OpenTelemetry hooks. Fortio Proxy can provide HTTPS with automatic certificates and multiplex gRPC and HTTP behind one port. Installation options include Docker, Go, binaries, Homebrew, and a Windows ZIP.
