Cascii is a web-based ASCII and Unicode diagram builder written in vanilla Javascript.
It has zero dependencies on any servers, web packing, libraries, and is no-markup and no-stylesheets. You can start building diagrams by simply opening the cascii.html file in a browser. Cascii is also hosted at cascii.app where you can get short links to your diagrams, open an account, etc.
Here is a diagram built with Cascii that loosely explains how Cascii is structured internally:

If you are not making changes, it's recommended to use cascii.app directly so you can take advantage of short links and save your work. Locally, short links will not appear in your exports.
