Katalon Studio
Best record and playback alternative to Selenium IDE


On August of 2017, Mozilla officially announced that the Firefox add-on Selenium IDE will no longer work on Firefox version 55 and above, citing switching of extensions from XPI to widely used "Web Extension" format(used by Chrome plugins). This lead to our search for a "Record and playback" alternative for Selenium IDE users and eventually, the discovery of Katalon Studio.
