HTTP load testing tools

HTTP remains the common denominator for API and web performance testing. The market spans one-shot CLIs, open-source engines, enterprise suites, and managed cloud generators.

This page filters the catalog to tools that list HTTP or HTTPS support. Use it as a map: micro-benchmark CLIs for raw throughput, code-first engines for scenario logic, and cloud platforms when you need elastic multi-region load without owning generators.

Do not pick solely on peak RPS claims. Match scripting language, CI integration, protocol extras (HTTP/2, gRPC, WebSocket), and operational cost. Discontinued products stay listed so old bookmarks still resolve to successors.

From here, open tool entity pages for specs and FAQs, or jump into static vs pages for Tier-A head-to-heads like JMeter vs k6.
