SwiftServers is a Minecraft hosting platform that is actually free and still feels pro. I checked it out and it is made for people who just want to start a server fast without paying.
You can make a vanilla SMP with your friends or run a Paper or Spigot server. The server starts in just a few seconds so you do not sit in a long queue. They say they do not cap player slots so you can invite as many people as you want.
The control panel is custom and not just some basic skin. It looks clean and is really simple to understand which is nice if you are not super technical. It also has backups that you can create and restore which helps if someone messes up your world.
The hardware looks strong for a free host. Each server gets 1.5 GB RAM 10 GB NVMe SSD storage and runs on AMD EPYC Rome with a 1 Gbit network. There is also enterprise level DDoS protection so your server is safer from attacks.
You do not need a credit card and there are no hidden fees. It is just set up your server and start playing. If you want free hosting that is not laggy and clunky this one is worth trying.
