I ended up on Piwigo. It’s pretty fully featured and allows you to set up access controls for groups. Also has client apps.

These are fully stand alone. Downloadable. So not strictly hosted I guess?

I like both these:

yEd (https://www.yworks.com/products/yed)

Dia Diagrams (http://dia-installer.de)

I think yEd had a free version but closed source.

This worked well for me and it gave me a spreadsheet (.csv) of my posts and comments.

Mine took about 15 minute to scrub 10 years and about 2000 comments. It missed a few so I manually edited and then deleted those.

Take note… I’ve heard (anecdotally), if you want your history backup, do not interrupt the process or close the window.

./configure and chill?
