Description

MarkChart is designed exclusively for previewing and editing Mermaid diagrams. Start with a built-in template to instantly create sequence diagrams, state diagrams, flowcharts, and more. Or begin with a blank document to write your own diagram from scratch. MarkChart can also be used in combination with an external editor, diagrams automatically update when changes are made.

Mermaid is a Markdown-inspired text syntax to define diagrams. MarkChart will render a nice looking sequence diagram if you write the following text in your Markdown documentation:

```mermaid
sequenceDiagram
Alice->>John: Hello John, how are you?
John-->>Alice: Great!
Alice-)John: See you later!
```

Simple to use, works right away, excellent.

From downloading it, it took about 5 minutes to understand the UI, get a sequence diagram rendering, and exported to a PNG. Excellent.

(My only little nit is that I wish it watched the underlying markdown file, so that it noticed changes produced when I modify it with another editor.)

Almost there

This is quite good... however, I can't seem to change my background color to white. If I use the base theme and set the background color, the setting is ignored.

I'd also like the ability to set a zoom factor when exporting images. Other than that, I have absolutely no complaints. It works as advertised, is fast, and seems to be stable.

Fixing those two issues will each earn back a star in the review!

Developer Response ,

Thank you for your feedback! We’re happy to share that in the latest version of MarkChart, PNG exports now have a transparent background by default. You can also customize the background color in the preferences. —Alex

Very helpful today

I was looking to export a number of diagrams at work today, and the combination of a UI based renderer and a terminal utility was a great help. I could tinker with layout and margins and once comfortable, could run through my whole project. Well worth the few dollars for the paid version
