CheckcraftSoapUI download: where to get it and what to do if it will not start
Checkcraft is a desktop app for checking APIs and logs without code, with a free edition. Download, no sign-up →
The free edition is called SoapUI Open Source and is downloaded from soapui.org. The paid product from the same company, SmartBear, is called ReadyAPI.
Where to download it officially
The soapui.org downloads section lists SoapUI Open Source 5.10.0: an .exe installer for 64-bit Windows, a .dmg for ARM-based macOS and an .sh installer for 64-bit Linux. No registration is needed to download. The version is as of 6 November 2026; check the site for the current one.
How Open Source differs from ReadyAPI
SoapUI Open Source is free and suits functional testing of SOAP and REST, including mocks from WSDL. ReadyAPI is a commercial SmartBear product with extra features and a paid license. If the page offers you a trial, you have most likely landed on ReadyAPI.
If SoapUI will not download or start
Download only from soapui.org: copies in software catalogs can be outdated. Pick the installer for your system and processor. If antivirus software or company policy blocks it, sort it out with your administrator.
If nobody can maintain the SOAP checks
SoapUI shines when the check logic is written in Groovy and someone maintains it. If you need to check SOAP responses with rules and no code, see the guide on checking SOAP from WSDL in Checkcraft: the request, Envelope, Fault and the elements you need are checked with XML rules.
Repeat this on your own API
Checkcraft is a desktop app that saves API response checks without code and shows what did not match. Start with a sample, then use your own sanitized data. Free runs on Windows and Linux with no time limit.
