SwiftServers is a Minecraft hosting platform that is actually free and still feels professional. I checked it out and you can spin up a server really fast and it does not feel laggy or clunky.
They use a custom control panel that they built from scratch. It looks modern and is easy to use so you do not need to be a tech pro to run a server. You can make a normal vanilla SMP or go straight into heavy modpacks.
There is one click support for big modpacks like Better MC RLCraft and All The Mods plus other Modrinth packs. So if you like modded survival this is super helpful.
The hardware is solid. Each server gets 1 GB dedicated RAM an AMD EPYC Rome processor 10 GB NVMe SSD storage and a 1 Gbit per second network. They also do not limit player slots so you can invite as many friends as you want.
They have enterprise level DDoS protection and a built in backup system so you can create and restore backups quickly. This makes the servers feel a lot safer.
The best part is it is really free. You do not need a credit card and there are no hidden fees. You just sign up and your server can be ready in under a minute.
