CoffeeCup HTML Editor

CoffeeCup HTML Editor is an HTML editor. Originally created by Nicholas Longo and Kevin Jurica, it was first released to the public in August 1996. Until version 12.5 released in 2012, it was capable of WYSIWYG editing.

In later versions, editing is done using HTML code, supported and assisted by a number of built-in features to generate and check code. While coding, a web browser preview would continuously update in a separate window or a split part of the main editor window (split-screen editing). However, the running internal preview stopped working sometime in 2023, because it relied on the long-deprecated browser Internet Explorer, which Microsoft disabled in a Windows update that year. In a support answer in November 2023, the Sales & Support Manager wrote: "At this time we do [not] have an alternative for the internal preview. We are working to rebuild the whole app for Chrome but we don't have an eta [estimated time of arrival] yet for that. In the mean time you would need to use the external preview in the browser of your choice."

The external preview, in a separate window, can use any and all web browsers installed on the user's computer, but must be refreshed manually. It does not update continuously while coding.

According to the authors the editor was the first to support JavaScript (version 3.5 Sep. 1996), split-screen editing (version 4.0, March 1997) and built-in FTP upload (version 5.2, February 1998).

It was voted Best Windows HTML Editor in the About.com Readers' Choice Awards two years in a row in 2011 and 2012.
