One year of updates included, then 59 €/year if you want newer versions. Refund on request within 14 days.

* Ceiling on what you add by hand. What your Docker labels declare is never counted.
Each edition opens every window the one below it opens. The ceiling is a duration, not a list: a window shorter than or equal to the edition's ceiling is served, a longer one is refused by naming the edition that would open it.
Personal covers one person on infrastructure they own or run for themselves, freelancers included. It does not cover monitoring someone else's infrastructure, or reselling Maintenant as part of a service. Pro adds that right, support, and the features a team needs.
One person, your own infrastructure · no support commitment · One payment, and the license never expires. One year of updates included, then 59 € incl. VAT per extra year if you want the newer versions. Install Maintenant, then set your key in MAINTENANT_LICENSE_KEY
Yes. The demo runs Pro with every feature on. Pro has a 14-day free trial. Personal is refunded on request within 14 days.
Your key arrives by email within seconds. Set it in MAINTENANT_LICENSE_KEY and restart the container. Same binary, same data, nothing to migrate.
Nothing is deleted and nothing leaves your machines. The instance goes back to Community limits: Slack and Teams channels pause, history stays where it is, and everything comes back when you resubscribe.
No. You pay 149 € incl. VAT once and the license keeps working for good, on the version you have. It includes one year of updates. After that, new versions cost 59 € incl. VAT per extra year, and skipping that only means you stay on the version you already run.
The signed answer is cached on your machine. Your instance keeps its edition for 60 days without reaching the server.
Personal covers one person on infrastructure they own or run for themselves, freelancers included. It does not cover monitoring someone else's infrastructure, or reselling Maintenant as part of a service. That is what Pro is for.
Personal: ask within 14 days of purchase at hello@kolapsis.com. You are refunded in full and the key is revoked. Pro: cancel during the trial and you are never charged. The details are in the terms of sale.
