Träwelling is run by the Träwelling Team in their spare time, and the work on it is unpaid. Servers, backups and domains still cost money, though. On this page we lay open what we spend our money on.
Since our association was founded in spring 2026, we are able to accept financial contributions towards these costs. If you would like to help, you can find more information at traewelling.org/support-us. We are especially happy about standing orders, even small ones: they give us planning security for our ongoing costs. This support is and remains voluntary: Träwelling stays free of charge. Now and always.
