This LWN article provides background, motivation, and a summary of the functionality.
The name “DomTerm” is due tp that it works by manipulating the Document Object Model (DOM) of a browser: the nested structure of elements, text, and attributes. (Also, most other appropriate names were already taken...)
DomTerm is Free Software (open-source) available at https://github.com/PerBothner/DomTerm. The older JWebTerminal project was based on similar concepts, but was mostly written in Java using Javafx WebView.
domterm command takes multiple sub-commands,

The command automatically starts server if not already running.
Session managament, with detachable sessions, as in
tmux or GNU
A front-end based on Electron is now the preferred one.
We now support draggable tabs and panes. This uses GoldenLayout.
An experimental pager with optional automatic pause on each page.
DomTerm now handles the
vttest terminal test program
very well, including BCE (Background Color Erase).
The preferred “backend‘ is now libwebsockets. This is light-weight, does not require Java, is actively maintained, and enables serving http and the WebSockets on the same port.

The qtdomterm application is designed to replace your favorite standalone terminal emulator program. It uses QtWebEngine.
Mouse support using xterm protocols, used by
In addition, Alt-Click generates arrow-key events to move the caret
