Cascii v1.0.4 (beta)

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 (see the Cascii server repo).

Examples

Here is a diagram built with Cascii that loosely explains how Cascii is structured internally:
