I found SwiftServers and it is a Minecraft hosting platform that is totally free to use. It is made for people who want a server fast without the usual free hosting problems like long queues and lag.
They say they built their own control panel from scratch so it feels lightweight and easy to use. You can set up a Vanilla server with friends or run a Paper server and it can be deployed in seconds.
They support Paper Spigot and Vanilla. They also mention enterprise grade DDoS protection and a backup system so you can create and restore backups quickly.
For specs it comes with 1.5 GB dedicated RAM an AMD EPYC Genoa processor 10 GB NVMe SSD storage and a 1 Gbit uplink. They also say player slots are not capped.
They also say it is really free with no credit card and no hidden fees.
