Mustafa Bayramoglu builds Stresseur, the AI test engineer for APIs, and dev.tools, the open-source API testing tool. Before that he built Preflight, a Y Combinator company that automated UI testing.

The alternative to writing Postman collections by hand is generating them: from a spec, from recorded traffic, or from a flow. Here is what each path costs.

Keploy, Speedscale, WireMock and Hoverfly compared on the same criteria: where each one sits, what it installs, what it captures, and how it replays.

API tests go stale because they are hand-authored copies of a moving target. Four mechanisms keep API tests from going stale when the API changes.

Keploy vs Postman for AI-generated API tests, compared on input, output, mocking, CI and price, using only each vendor's own public documentation.

Load test an API with realistic user flows instead of single endpoints: the virtual user arithmetic, the ramp that finds the ceiling, and how to read the run.
