Fortio vs Taurus

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.

Taurus is a free, open-source framework for automating continuous testing. It wraps performance and functional tests and relies on tools including JMeter, Gatling, Locust.io, and Selenium WebDriver. Documented executors also cover JUnit, K6, Postman/Newman, PyTest, TestNG, and Playwright. Test scripts can be written in YAML or JSON, with configurable pass/fail criteria. Taurus can show live statistics in a terminal and generate interactive reports, JUnit XML, and CSV outputs. The project documents integrations with Jenkins, Bamboo, and TeamCity, and provides a Docker image. Installation can use Python’s package manager with `pip install bzt`; official instructions cover Linux, Mac OS, and Windows. Requirements vary by system and test type: Linux installation requires Python 3.7+ and Java, and some test types need additional software. Cloud-provisioned execution uses BlazeMeter locations and requires an API key in the cloud module settings. Taurus is licensed under Apache 2.0 and directs users to GitHub Issues and a support forum.
