Minecraft multiserver web interface?

I want to do a Minecraft server sponsorship, and am still looking for a good web interface that supports multiserver ie one user has the server the other another. Day webspace should not cost more than approximately 20 euro one-time.

Pterodactyl is well suited for such purposes because it works with Docker and, accordingly, can also limit resources well. In contrast to most other panels, it is modern and is being actively developed.
