What is Hoverfly?

Hoverfly is a lightweight, open source API simulation tool. Using Hoverfly, you can create realistic simulations of the APIs your application depends on.

  • Simulate network latency, random failures or rate limits to test edge-cases

  • Extend and customize with any programming language

  • Export, share, edit and import API simulations

  • CLI and native language bindings for Java and Python

  • REST API

  • Lightweight, high-performance, run anywhere

  • Apache 2 license
