Really useful for intercepting and mocking HTTP requests during development. Saves so much time when testing frontend integrations without needing a real backend running.

How do you scale against competitors

nhrdev
@nhrdev

@manickavel by combining api tester and mocker into one tool, and all rules and saved requests stays saved locally, nothing gets stored in my server or anywhere else
