Orion is a set of browser-based components that provide an extensible development platform for editing, navigating, searching, and working with source code management for web developers. The Orion server exposes REST APIs for file system, search, Git, and other services. The Orion client is written in HTML/JavaScript and runs in the browser, focusing on tasks for exploring and leveraging cross-site workflows. Orion uses a plugin architecture where plugins can be installed from any web server to extend Orion's capabilities.
