As Confluence Data Center (and the Open Souce license I am running on) ... is not gonna be around forever, I have started looking into altermnatives:

Confluence Cloud

First realisation was, that migrating to Confluence Cloud would cost me quite some money:

• As Confluence Free plan does not have Permissions, it cant be public, hence I need Confluence Standard plan
• As Confluence Free plan has 2 GB storage limit, I cant really use it

So:

And this is before any Apps (Plugins), I dont "need" at least:

• Draw.io
• Refined (Counfluence Cloud is not really a web-site app)

So - this will add up on a yearly basis....

I did some migrations tests over christmass 2024, and the result was acceptable, do Refined is a fresh setup in cloud...

Alternatives

xwiki cloud

I did som tests here, and even a small Confluence Space import. Conclusions are:

• XWiki is also pricy in cloud
• The Editor is good, but no more than this
• Pro stuff cost more money
• Confluence Cloud would be cheaper or same price, and with better functionality...

xwiki onpremise (Docker)

xwiki onpremise (Community edition) is nothing like the Cloud version. Conclusions are:

• Very basic wiki
• Editor is really old and not wsywig
• Extension download did not work very well

In short - not very interesting.....

Next step

I did google and looked, and in generel 2 conclusions came up:

• There is no free rides ind cloud (at all)
• Must onprime is old'ish and badly maintained

One Wiki that did stand out a bit, was DokuWiki that has a few good things:

• No database is used
• All content are filebased - hence management, data manipulation and migration is simple
• The eco-system seems alive and updated (more or less)

I did find a Confluence 2 DokuWiki migrator (pr. space) - https://github.com/mschlenstedt/confluence2dokuwiki

So DokuWiki could be an alternative...
