Fortio
Load testing and network measurement tool built for microservices, reporting detailed latency percentiles under sustained load.
- Actively maintained
- Well documented
- Permissive license
Overview
Fortio was built at Google/Istio to load-test microservices and measure how latency behaves under high concurrent load, reporting detailed percentile breakdowns rather than just averages. It supports HTTP and gRPC, runs as a CLI or library, and includes a small built-in UI for visualizing results.
Fortio is a fit for teams working with gRPC or service-mesh-based microservices who need precise latency-under-load measurements, complementing k6 (also in this catalog), which is more focused on general-purpose scripted load testing scenarios.
Why it's in this catalog
Catalog rating: ★★☆☆☆ (2/5)
