PlantUML

Renders UML diagram as defined in a text file. For full syntax of the text file, see: http://plantuml.sourceforge.net/index.html

Install the extension from Chrome Web Store.
Open text file from web server with UML diagram definition in browser (the text starts with @startuml).
See the rendered UML diagram!

Chrome does not allow fetching content from local files anymore, so you have to start a local web server that will serve the local text file. One simple way if you have Python 3 is to run python -m http.server command in the directory with your PlantUML files.

Features

Automatically updates the diagram when the file at given URL is changed.
You can use your own server by changing the server URL in the popup of the action button (action button is displayed while viewing PlantUML files).

User reviews

These summaries are automatically generated weekly using AI based on recent user reviews. Chrome Web Store does not verify user reviews, so some user reviews may be inaccurate, spammy, or outdated.

Pros

Very useful. I like that it refreshes when I save updates to the file in my text editor.
It is very cool, but there is a problem that the viewer will return to text for a seconds.

Cons

Doesn't work at all, often shows a broken image icon for UML files.
The diagram viewer recently stopped working on multiple machines.
Security concerns about user data being sent to an external server without permission.
The viewer does not support mindmap diagrams or the newpage command.
SVG formats need to be displayed in object tags for links to be clickable.
