Hoppscotch vs SoapUI / ReadyAPI

From $6 per user/month (Organization, billed annually; 25% more monthly)

Free tier available

Self-hosting the community edition is free. The Organization plan adds an admin dashboard and vendor support; the self-hosted Enterprise edition is quote-based.

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.

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.
