I found a vanilla Java SMP that runs on 1.21.11. It has around 20 players so it feels active but not crazy.
The world uses the Terralith data pack so the terrain looks way cooler when you explore. PvP is allowed but only if both people agree to it so it is not just random killing.
If you want to join you can send your Minecraft username to get in.
Chill Vanilla SMP With Terralith

casual survival vibesCollaborative building focusexplorer friendly worldshared shopping districtsocial survival server
Vinterra is a Hermitcraft inspired SMP world that has been running for about three months. It has an active community with around 20 to 30 members and they want about 10 more players to join.
People on here do a mix of stuff like exploring building and redstone. You do not have to be some crazy builder to fit in. The vibe is more about being part of the community and playing together.
They host events and they run game nights most weekends. There is also a Decked Out style game being built right now and they say more interactive events are coming.
They do interviews on Saturday and it sounds quick and easy.
GG.MINEWIND.NET New Server IPWhitelist Lifesteal SMP With Voice Chat

I found a small whitelisted Minecraft Lifesteal SMP that is getting opened again. It is being run by Genesis and a friend and they want to grow it with a few more players.
It has simple voice chat and they are looking for friendly active people around 12 to 16. The server has not started yet and they plan to start when they feel like there are enough players.
It is hosted on Aternos and it is meant to be a chill SMP where you can actually know the people you play with.
GG.MINEWIND.NET New Server IPFinally Ditched Laggy Hosting

I found a vanilla Minecraft server host that seems built for small groups like 5 to 15 players. It is the kind of setup where you pick Minecraft and a plan and it comes online super fast.
The storage is NVMe so chunks load quicker and world generation does not crush the TPS like before. It also has DDoS protection included which helps a lot if your server has been hit in the past.
It uses a Pterodactyl panel so it is easy to handle plugins backups and the console right in your browser. Pricing starts at 4.99 a month for 1.5GB and the 4GB plan is 14.99 a month.
The only downside is there are only US and EU locations right now so other regions might feel laggy. There is no one click modpack installer yet so you have to upload the server jar yourself. Support is not 24 7 live chat but email replies have been fast and there is a 7 day free trial to test it.

I found a modded Java SMP that runs on 1.20.1 Fabric and it is built around survival with a bunch of fun mods
It has Create for machines and contraptions plus immersive aircraft and small ships so travel feels way more cool. There are backpacks and gravestones too so it feels less painful when stuff goes wrong
It also has more biomes and building mods so exploring and making nice bases is a big part of the vibe. The server is looking for more active players right now
