Essential Cloud Essential Launchpad Essential demo

Essential is the enterprise architecture tool for bringing your EA to life.

Initially starting as a purely open source EA tool, Essential has grown to be an EA tool for organisations of all sizes, where it is used as an interactive tool for visualising, traversing and diving into your enterprise architecture. Essential now has variants to support both those interested in a commercially supported enterprise architecture platform, as well as those who want to manage their architecture using open source technology.

Built, and continually evolving, based on our experience as enterprise architecture consultants to many of the world's top organisations, Essential has been built for architects, by practising architects, with a meta model and views geared towards delivering stakeholder value and answering the key enterprise architecture questions.
