Cavisson NetOcean vs Hoverfly

Cavisson NetOcean simulates backend applications and third-party systems so development and testing teams can work without those dependencies. It captures production-like behavior and performance characteristics, then supports custom responses, boundaries, and error conditions. Supported protocols include HTTP, HTTPS, HTTP/2, REST, SOAP, Hessian, IMAP, FTP, DNS, XML, JSON, WebSocket, JDBC, TCP, and UDP. Messaging technologies include TIBCO JMS, TIBCO-EMS, IBM MQ, and Kafka. REST APIs and command-line interfaces connect NetOcean with CI/CD workflows. A web portal and thick client create, deploy, and manage virtual services. Service definitions support version control and rollback. The product is designed as an appliance and can also run as a virtual machine, with self-hosted, web, and API access. Cavisson states that one appliance can handle 100–1000 times more load than legacy solutions. Pricing is on request, and a free trial is listed. Support includes 24×7 application health monitoring and testing assistance.

Hoverfly Cloud is a hosted API simulation and mocking platform for testing without live API dependencies. It handles HTTP/S services including REST, SOAP, XML, JSON, and GraphQL. Users can capture and replay traffic, generate simulations from OpenAPI specifications, and match requests by methods, headers, parameters, and bodies. Simulations can delay responses, inject faults or errors, and modify replies. A command-line interface supports scripted configuration and testing pipelines. Hoverfly and hoverctl binaries run on macOS, Linux, and Windows, while documentation covers Docker and Kubernetes installation. The underlying Hoverfly framework is open source under Apache 2, has no GUI, and is generally run locally or in a user’s infrastructure. Cloud use cases include performance testing, functional testing, and development.
