SwiftServers is a free Minecraft hosting platform where you can spin up a server super fast. It is meant for people who want a simple vanilla SMP with friends or a Paper server without dealing with the usual free host problems.
The big thing here is the control panel. It is fully custom made and built to feel lightweight and easy to use. It also supports different server types like Vanilla Spigot and Paper.
They say the setup is quick and the platform is focused on performance. You get 1.5 GB dedicated RAM an AMD EPYC Genoa CPU 10 GB NVMe SSD storage and a 1 Gbit per second uplink. There is DDoS protection and a backup system so you can create and restore backups fast.
They also say it is really free with no credit card and no hidden fees.
