SwiftServers is a free Minecraft hosting platform and it tries to fix the usual free host problems like queues and lag. It has a custom control panel that they built themselves and it is made to feel modern and easy to use.
You can spin up a server really fast and it supports Paper and Spigot. It works for a simple vanilla SMP with friends or a Paper server if you want that style.
They say it comes with enterprise grade DDoS protection and a backup system so you can create backups and restore them fast.
The listed specs are 1.5 GB dedicated RAM and an AMD EPYC Rome CPU with 8 cores plus 10 GB NVMe SSD storage and a 1 Gbit uplink. They also say they do not cap player slots and it is free with no credit card and no hidden fees.
