OpenLegacy helps us set the mainframe free, finally. Instead of being a prohibitive factor for new projects, it's now the enabler - witk OpenLegacy generated APIs that connect to any other system in our environment.

"The ""wow moment"" for us when working with OpenLegacy came when we exposed a Swagger API with account data from our mainframe. It only took us a few hours with OpenLegacy - it would have taken weeks otherwise"

Jeff Mason, Fern
OpenLegacy let us connect our iSeries applications to our insurance agent portal without changing our COBOL applications, which would have been a huge, expensive headache. We couldn't believe OpenLegacy was able to conform to all of our security, performance, and design constraints - and do so within days.
