The TIBET Active Client Environment™ (ACE™) is a true WYSIWYG development suite that virtually eliminates reload/preview delays. Whether you’re using the TIBET ACL or not, ACE will dramatically reduce your development and debug times. Attach to any window and interactively inspect, edit, and save changes. Using ACE™ and the TIBET™ ACL is like having “Smalltalk for the web”. ACE supports a highly interactive development cycle that makes it perfect for XP-style web development. With dynamic importing, type and method browsing, an interactive JS/XML shell, dynamic client-side tag rendering, and a variety of other tools, ACE is the premier IDE for client-side development. It’s also one of the only true WYSIWYG web tools available — you see what the browser sees.
