Gate One is an HTML5-powered terminal emulator and SSH client

About Gate One

Gate One is an HTML5 web-based terminal emulator and SSH client. Top features:

• No browser plugins are required!
• Supports multiple simultaneous terminal sessions.
• Advanced terminal emulation including support for 256 colors, fancy text styles, and more.
• Supports displaying PNG and JPEG images inline within terminals (see screenshots).
• Type in your native language! Gate One supports Unicode, non-English keyboard layouts, and localized strings (internationalization or i18n).
• Natural copy & paste: Highlight text and use your browser's native context menu. On Linux desktops you can also middle-click-to-paste.
• Terminal sessions can be resumed even if the browser is closed or disconnected. They can also be resumed from a completely different computer.
• Supports server-side logging of user sessions via any combination of syslog, remote syslog, or directly to disk.
• Gate One can be embedded into--and completely controlled by--other applications. A few lines of JavaScript is all it takes!
• Many authentication mechanisms are supported: Anonymous, Kerberos (Single Sign-On with Active Directory!), PAM, Google Auth, and there's an OpenID-like WebSocket API for applications embedding Gate One (see the chat app in the tests directory for an example of how it works).
• Gate One is easy to customize: Themes and plugins can add features or override just about anything. In fact, Gate One's SSH functionality is implemented entirely via a plugin.
• Plugins can be written in any combination of Python, JavaScript, or CSS.
• The Gate One server can be stopped & started without users losing their running terminal applications (even SSH sessions stay connected!).
• The SSH plugin allows users to duplicate sessions without having to re-enter their username and password (it re-uses the existing SSH tunnel). It also supports key-based authentication and includes an SSH identity manager that supports RSA, DSA, ECDSA, and even X.509 certificates.
• The Logging plugin includes a Log Viewer that allows users to sort, view, and even export recordings of their terminal sessions to self-contained HTML files that can be shared. Demonstrating anything on the command line can be as simple as performing the task and exporting the log!
• The Playback plugin allows users to "rewind" and play back their connected terminal sessions in real-time, just like a video! This can be done via the playback controls or by holding the shift key while scrolling.
