“I’m interested in understanding the full cost structure for this tool. Could you please clarify if the tool is entirely free to use, or if there are any costs involved with patch upgrades, additional features, or any other aspects of ongoing maintenance? Specifically, I’d like to know if there are any hidden fees or subscription models that might apply after the initial download or purchase.”
Do you see any pricing on the community version page?
Why would you be able to download a piece of software for free and then be locked in with updates?
If you don’t want or can’t pay for Zammad support, then that is absolutely fine. We as vendor pay our bills via custom developments, feature sponsorings and our support customers.
What is not free is the time you take to install and maintain Zammad, nor the server you have to run / rent to do so.
You can use Zammad completely free of charge.
Of course you have to pay the costs for your server yourself
