Hoppscotch vs SoapUI / ReadyAPI

From $19 per user/month (indicative, team plan)

From $829 per year (indicative, ReadyAPI Test module)

Self-hosting the community edition is free. Paid plans add team workspaces and enterprise SSO.

ReadyAPI is licensed per module — Test, Performance, Virtualization — and buying all three multiplies the cost.

Free cloud tier and a fully functional self-hosted community edition.

SoapUI open source is free and covers SOAP and REST functional testing.

• Nothing to install — genuinely useful for onboarding and for locked-down machines.
• Self-hosting is a single container, so internal deployment is trivial.
• Very light and fast.

• 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.

• Browser CORS restrictions require a proxy or the desktop agent for many real requests.
• Fewer advanced testing and mocking features than Postman.
• Smaller community.

• 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.

Teams that want a self-hosted, no-install internal API client.

Enterprises testing SOAP services, message queues and legacy integration layers.
