SummitSurvival is a hard mode vanilla plus server that feels like a real survival world with friends. It is free to play and the few extras are just there to make life easier not to make it pay to win.
The server runs on 1.21.x and sticks close to normal Minecraft. You get simple commands like spawn and sethome and faster nights but not a bunch of crazy plugins. Mob rates are vanilla and there are no weird limits on what you can build so it feels like a normal world just with more people.
There are no land claim plugins so everyone is expected to respect each other. The rules say you cannot hack or use x ray and you cannot mess with other player builds or their mobs. You should ask before you build too close to someone. Dupes that give tons of different items are not allowed but small ones like rail or string dupes are ok.
The economy is item based and uses raw gold for trading and for the player run shopping district. There is also a donor rank but it only gives some extra bonuses that are mostly cosmetic so regular players can still keep up fine.
The staff team is small and they stay out of the way unless someone is cheating or griefing. The community talks a lot and people like to hang out and chat while they play so it feels pretty active.
