About Hoverfly

Hoverfly is an open-source service virtualization tool developed by SpectoLabs that enables developers to capture and simulate HTTP(S) traffic for robust integration testing. By allowing teams to create realistic API simulations, it eliminates dependencies on unstable external services or unavailable environments. Its primary differentiator is its lightweight architecture, which supports both stateful behavior and multiple simulation modes, making it ideal for CI/CD pipelines. Hoverfly empowers engineering teams to accelerate development cycles and improve software reliability by providing consistent, predictable responses during the testing phase.
