Top features: * No browser plugins required! Say goodbye to the security problems of Java, Flash, and ActiveX. * Multi-user and multi-terminal: Hundreds of simultaneous users and terminals can be served from ho-hum hardware. * Advanced terminal emulation including support for 256 colors, fancy text styles, and more. * Supports capturing and displaying images and PDFs inline within terminals (see screenshots). * Type in your native language! Gate One supports Unicode, international keyboard layouts, and localized strings (internationalization or i18n). * Natural copy & paste: Highlight text and use your browser's native context menu. On Macs you can use ⌘-c and ⌘-v and on Linux desktops you can middle-click-to-paste. Shift-Insert works too! * Terminal sessions can be resumed even if the browser is closed or disconnected. They can also be resumed from a completely different computer. You'll never have to worry about the office VPN disconnecting again! * Supports server-side logging of user sessions via any combination of syslog, remote syslog, or directly to disk. * Gate One can be embedded into any web application. A few lines of JavaScript is all it takes! There's an interactive tutorial covering how to embed available in the `tests` directory (hello_embedded). * 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, and 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 SSH plugin also provides a library of functions that *other* plugins can use to seamlessly execute background operations on the currently-connected terminal. You can capture this output from JavaScript and do whatever you want with it. * The Bookmarks plugin lets you keep track of *all* of your hosts with support for tagging, sorting, and includes a super fast search. It was built to handle thousands of bookmarks and can be used with whatever URLs you want--it isn't limited to SSH! * 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 clicking a button! * 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. * The Convenience plugin adds many convenient capabilities: * IPv4 and IPv6 addresses become clickable elements that can perform a reverse DNS lookup. * The output of 'ls -l' is transformed into clickable elements that can perform user and group lookups, convert bytes into human-readable strings, and even tell you what the 'chmod equivalent' is of the permissions field (e.g. clicking on 'crw-rw-rw-' would tell you, "(Character Device) with permissions equivalent to 'chmod 0666'"). * Automatic syntax highlighting of syslog messages. * The Example plugin demonstrates how to write your own plugins and shows off the SSH plugin's exec_remote_command() functionality. * Gate One works with Python 2.6+, Python 3, and even pypy! * The daemon that acts as the web server for Gate One is small and light enough to be included in `embedded devices `_.

The HTML form is pre-built and ready-to-read. Demo ---- Just press the ESC key on any page at http://liftoffsoftware.com/ to have Gate One drop down into view, Quake-style! Other Notable Bits ------------------ Gate One's `termio` and `terminal` Python modules can be used together to automate, screen-scrape, and completely control terminal applications. The `expect() `_ function can be used as a replacement for `pexpect `_ that has some additional features and benefits: * It can be used asynchronously: It won't block which means it is perfect for executing commands from a web application. * It supports sophisticated decision trees and callbacks: You can completely re-define all patterns and callbacks on-the-fly based on whatever conditions you want.
