SwiftServers is a free Minecraft hosting platform where you can spin up a server super fast. It is trying to be the opposite of the usual free hosting stuff like long queues and lag. They say the control panel is fully custom made and meant to be lightweight and easy to use.
You can start a vanilla SMP with friends or run a Paper server. They also support Spigot and Fabric plus other server types like Hytale Luanti and ClassiCube.
They talk a lot about safety too with DDoS protection and a backup system so you can create and restore backups quickly. The free plan listed comes with 8 GB RAM a Ryzen 5 3600 10 GB NVMe SSD and a 1 Gbit uplink. They also say they do not cap player slots and you do not need a credit card.
