Gliffy

Gliffy is software for diagramming via an HTML5 cloud-based app. It is used to create UML diagrams, floor plans, Venn diagrams, flowcharts and various other kinds of diagrams online. Gliffy diagrams can be shared with and edited by users in real time. The SaaS is supported in all modern web-browsers, including Google Chrome, Firefox, Safari and Internet Explorer 9+.
Gliffy's developer, the self-funded company Gliffy, Inc., was acquired by Rogue Wave Software in October 2018, and Rogue Wave was subsequently acquired by Perforce Software in January 2019.
History.
Gliffy was founded in 2005 by friends and former coworkers, Chris Kohlhardt and Clint Dickson. The two software engineers saw a need for an online diagramming tool and decided to leave their full-time jobs and start a company to develop it. Kohlhardt contacted Mike Cannon-Brookes, one of the founders of Atlassian, an Australian enterprise software company. With his encouragement, Kohlhardt and Dickson created a Gliffy plugin for Atlassian’s collaboration product Confluence, and business took off. In May 2006, Gliffy announced its public beta and by 2007 the beta was removed. In 2009, a new Gliffy plugin for Atlassian's JIRA product was unveiled and in 2010 Gliffy was added to the Google Apps marketplace. In early 2013, Gliffy moved to an all HTML5 platform, at the same time adding Visio support. Gliffy integrates with Google Apps, Google Drive, JIRA, and Confluence, and has over two million registered users. It was acquired by Rogue Wave Software in October 2018, which was then acquired by Perforce in January 2019.
