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 inside of 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. Auditability compliance doesn't get much easier than placing a Gate One server in front of critical hosts!
  • 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 terminal sessions like a video. This can be done via the playback controls or by holding the shift key while scrolling.
