Browse all what you can do with examples in the documentation.

More details

TextDiag offers different diagram generation engines, such as BlockDiag and PlantUML, what allow to choose between a number of diagram types and styles, including generic Graphviz diagrams.

Designed for security, data is stored in Atlassian Confluence databases -including final graphics- and nothing in our servers. All communications are cyphered. In addition, all communications are POST, because it is safer despite slower for some diagrams.

With PlantUML engine, the available diagrams are:

And BlockDiag engine adds:

PlantUML diagrams have been tuned in order to use same colors than Confluence, allowing you to create beautiful documentation.

Awesome plugin. It worked great while we were on the old confluence editor. But we recently moved to the new Confluence editor (https://confluence.atlassian.com/confcloud/confluence-editing-improvements-945107733.html) and this plugin seems completely broken. Any chance you can fix this soon?

I'm on it.

I hope to solve it in a couple of weeks or before.

Thank you for reporting.

Great idea, unfortunately not tested, yet.. as we use Confluence-server. Any plans to introduce this addon for Confluence-server, also? Thanks

I appreciate that this was free and useful, but it had two bugs that stopped us from using it. 1. if there were two diagrams on the same page, it always showed the same rendered image 2. it didn't seem to apply the default styles

Hi there,

First of all, it is currently free, but that was not the intention on long term.

If you found two diagrams in the same page, maybe it is because they had the same name. Check if you it still happens after changing the filename in the second tab. This usually happens if you copy one script.

Yes, it doesn't apply default styles. I hope to solve this as soon as I can, hopefully in a couple of months.

It's a pitty you to decide leave using it, but thank you anyway by your feedback.

PlantUML + Confluence is the best way to maintain diagrams!
