I found a hardcore social experiment server on Java 1.21.1 where you only get one life. If you die then you are done so everyone has to play smart.
There are two islands and they feel really different. Winter is a brutal wasteland but it has rare minerals. Summer is more fertile and easier to live in but it can get crowded fast.
The server uses one global economy so what happens on one island can affect the other. Simple Voice Chat is required so you have to talk in game and deal with people for real.
A lot of spots are already taken and players apply to join. The whole vibe is surviving with others while the islands compete and the choices actually matter.
One Life Island War Experiment

GG.MINEWIND.NET New Server IP100 Players One Life Island War

This is a hardcore Java server on 1.21.1 that is set up like a social experiment. There are 100 players and you only get 1 life so every fight and every mistake matters.
Players split into two factions on two different islands. Winter is a harsh place with rare minerals so it is risky but powerful. Summer is easier to live on and good for growing stuff but it can get crowded fast.
Simple Voice Chat is mandatory so people actually have to talk and make plans. There is also a global economy to control so trading and power moves are a big part of it. Applications are open right now.
GG.MINEWIND.NET New Server IPUnscripted Unstable SMP Roleplay Chaos

This is an Unstable style SMP idea but it is meant to be unscripted so real players can actually change what happens. It is more of a roleplay kind of server so people are supposed to act things out and make stories.
It has a 100 player cap at once. You get 3 lives and there is a chance to get revived so deaths matter.
The world has weird stuff like the Farlands and even orbital strike cannons. There is no underworld though. You can play from Java or Bedrock since it is crossplay.
The main rule is no hacking. If you want to grief you technically can but they really want you to do RP stuff instead of just ruining everything for no reason.
GG.MINEWIND.NET New Server IPUnstoppableSMP One Life Survival

I found UnstoppableSMP and it is based on UnstableSMP. It is a survival server that is open for everyone.
You can join on Java or Bedrock and it also allows cracked players. The version listed is 1.21.11.
The big rule is you should not die because you only get one life every 12 hours. It makes everything feel more serious and kind of stressful in a fun way.
GG.MINEWIND.NET New Server IPOne Life Hardcore SMP Season Two

I found a hardcore survival SMP called LUMI HARDCORE and it is mostly vanilla with one big rule. You only get one life.
If you die you do not come back right away. You end up in an infirmary until the next reset and there are no revives.
The world resets every 60 days so each season uses a brand new seed. That means nobody keeps a huge head start for long and everyone gets a fresh start together.
It is whitelisted so you have to apply to get in. It also supports both Java and Bedrock since crossplay is enabled.
GG.MINEWIND.NET New Server IPDRACONIS SMP 3 LIVES PVP CHAOS

Draconis SMP is a survival server where everyone starts with 3 lives. If you lose them all you get banned. The only way back is if your team revives you and it costs valuable resources.
The server has custom mace rituals. You can get custom maces with special powers and crafting one will trigger a ritual.
If you hold the Ender Dragon Egg you get helpful potion effects. The server also has competitive PvP and server wide events. The staff is active and tries to keep things fair. Players can vote in polls that actually matter and the season is meant to be one full month of intense gameplay.
GG.MINEWIND.NET New Server IPUnstoppableSMP One Life Daily Hardcore

I found a new Minecraft server called UnstoppableSMP and it is a hardcore style server where you only get one life per day. The owner said they might change it to one life every 12 hours later.
It is meant to be more of a normal survival experience with lots to explore and no scripted stuff. The server just started so it is basically empty right now.
It also supports cracked players and Bedrock players. The server is still in maintenance and it will be opened when the owner is ready.
GG.MINEWIND.NET New Server IP3 Lives SMP Roleplay Worldbuilding Adventure

The Garden is a Java 1.21.11 survival multiplayer server that leans hard into worldbuilding adventure and roleplay. It has a bunch of plugins that add flavor but it still feels like survival.
The main thing is the life system. You start with 3 lives and you only lose lives through PvP. If you lose them all you turn into a ghost and only you will really know what happens after that.
Some vanilla stuff is turned off to fit the roleplay better. Elytra and ender chests are disabled so people actually build roads and towns and real infrastructure.
Players can lock chests using trial keys and you can craft lockpicks to break in. You can also make chest shops and brew alcohol and beers. There are lots of quality of life features too.
When you join you wake up above the clouds then you stick the landing to start. You can descend the Monolith then pick a race like Human Halfling Orc Elf and more. After that you wake up on the docks of Isla De Viva Eterna and sail out to find new land or settle with others. The server is meant to be relaxed with optional challenges and it says there is no pay to win with active staff and mods.
GG.MINEWIND.NET New Server IPPerils In Paradise 5-Life Lore SMP

Perils In Paradise is a lore based Minecraft server that is built to be fun and fair and not pay to win. It is made to be really good for streaming and content because the server heavily supports people who want to create.
Everyone gets 5 lives and you only lose lives from PVP. That means mobs do not take your lives so you can still explore and survive without getting punished for random stuff.
The server uses minimal mods so it should run fine on most computers. The main mod is proximity chat so players can talk when they are close which makes surprise moments and mystery way better.
If you are new to content creation there are people around with different levels of social media experience who can help. If you are not a creator that is fine too because they are taking applications from anyone and want lots of new people to join.
GG.MINEWIND.NET New Server IPAustralia Timezone Life Series SMP Tryouts

I found a Java modded server project that is trying to run a Life Series style season with a full modpack that includes the different Life Series modes. The main idea is everyone records together so it feels like an actual series and not just random playtime.
They want people who can match Australian Central Daylight Time or at least can show up when recording happens. You need Discord to plan sessions and you need Modrinth plus Simple Voice Chat so everyone can talk in game.
Any age and any gender is welcome and the host is 17. Content creators are preferred but normal players can join too as long as you actually have time to record and want to play for fun.
