Hoverfly vs SoapUI / ReadyAPI
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Free tierWhat drives the bill
The metric that actually scales your invoice.
Free and open source. You pay in engineering time and CI minutes.
SmartBear publishes no ReadyAPI price; the pricing page is a quote request. ReadyAPI is licensed per module — Test, Performance, Virtualization — and buying all three multiplies the cost, with floating licences for CI costing more than fixed seats.

Strengths
- Capture mode produces a realistic simulation from live traffic with no authoring.
- Latency injection makes it useful for performance and resilience testing too.
- Small footprint — a single Go binary.
- Unmatched SOAP, WSDL and JMS support for legacy enterprise integration work.
- ReadyAPI bundles functional, security, load and virtualisation in one product family.
- Groovy scripting escape hatch for anything the GUI cannot express.
Limitations
- Smaller community and slower development than WireMock.
- Proxy configuration in complex networks takes effort.
- Captured simulations need periodic refresh.
- Dated Java desktop UI that feels heavy next to modern clients.
- Project files are XML and merge badly in version control.
- Modular licensing gets expensive fast.
Best for
Teams needing lightweight service virtualisation against real recorded traffic.
Enterprises testing SOAP services, message queues and legacy integration layers.
All of these integrate with: Jenkins.
