Hoverfly (Open Source) is an open source API simulation tool developed by SpectoLabs. According to the vendor, it is designed to assist software developers, quality assurance/testers, DevOps engineers, and API product managers in creating and testing API simulations for their applications. The tool is suitable for companies of all sizes, from small startups to large enterprises, and finds applications in various industries, including e-commerce, to simulate API interactions and ensure operational reliability.

## Key Features

**API Simulations**: According to the vendor, Hoverfly allows users to create realistic simulations of APIs, replacing slow and unreliable dependencies, and customize simulations using any programming language.

**Export and Import Simulations**: The vendor claims that users can easily share and collaborate by exporting and importing API simulations in various formats, such as JSON and YAML.

**CLI and Native Language Bindings**: The vendor states that users can interact with Hoverfly via the Command Line Interface (CLI) and integrate it directly into Java applications using native language bindings.

**REST API**: According to the vendor, Hoverfly offers a REST API that enables users to programmatically interact with the tool, facilitating seamless integration with other systems and tools.

**Simulate Network Latency, Failures, and Rate Limits**: The vendor claims that users can test application resilience and performance by simulating network latency, random failures, or rate limits in API responses.

**Lightweight and High-Performance**: According to the vendor, Hoverfly is designed to be lightweight and high-performance, ensuring minimal impact on application performance.

**Apache 2 License**: The vendor highlights that Hoverfly is released under the Apache 2 license, allowing users to use, modify, and distribute the tool freely, promoting transparency and community collaboration.

Hoverfly's on-premise edition, developed and supported by SpectoLabs in London and available free and open source, is designed to replace unreliable test systems and restrictive API sandboxes with high-performance simulations in seconds. It can be run on MacOS, Windows or Linux, or it mayuse native Java or Python language bindings to get started quickly.
