SwiftServers is a free Minecraft hosting platform where you can spin up a server super fast. It is made for people who want to start a vanilla SMP with friends or run a Paper server without dealing with long waits.
The panel is custom built and it is meant to be lightweight and easy to use. You can choose server types like Paper Spigot and Vanilla.
They also talk about security with DDoS protection and an instant backup system so you can create and restore backups fast. The plan listed comes with 8 GB RAM a Ryzen 5 3600 10 GB NVMe SSD and a 1 Gbit uplink. They also say there is no player slot cap and no credit card needed.

I found a free Minecraft hosting service made for small servers and friend groups. It is also good for testing plugins or just messing around without paying.
The specs they list are 3GB RAM with 2GB RAM and 1GB swap. It also has 5GB storage and 1 vCore CPU. They say it is 24 7 uptime.
It is not top tier but it should be enough to actually play with friends. Feedback is welcome and right now they are only focused on free Minecraft hosting.GG.MINEWIND.NET New Server IP
