AjaxSwing automatically converts Java desktop applications to web applications. It was the first product built by our company and is still the only platform capable of automatically running Java Swing apps on mobile devices running iOS and Android. For the first 10 years (10 YEARS PEOPLE!) we were struggling with changes to AjaxSwing because we could never truly understand the effects of each code change. We wanted to automate the UI regression testing with Selenium and tried a few other alternatives, but since none were testing the page visually these tools failed to detect broken CSS and HTML formatting. Touching anything in Java or CSS code was like walking on a minefield with delayed explosions but real pain.
