TL;DR: A Realm is the easiest way to run a private Minecraft server for your family. It's safer than an SMP for kids, more expensive at scale, and has built-in backups. This guide covers Realms vs SMP, the pricing math, whitelist management, behavior rules that actually work for kids, the plugin alternatives if you outgrow Realms, and the question every parent eventually asks: do you really need a Discord for the family Realm?
There's a moment in every Minecraft-parenting journey when your kid asks "can I have my own server?"
The honest answer is "yes, and you'd probably love it, and it's going to require some work from you." This guide is to keep you out of the dishonest "let me Google that and get back to you" answer.
Section 1: Why Realms vs SMP servers
Realms (Mojang official):
- $7.99/month for the 10-player tier (Realms Plus); $4 for 2-player.
- Hosted on Mojang's infrastructure. You don't manage anything.
- Auto-backups, auto-restore, basic moderation tools.
- Whitelist-only.
- No mods, no plugins, just Marketplace add-ons.
SMP (self-hosted server):
- $5-30/month for hosting; $0 if you self-host on a home computer.
- You manage everything: updates, backups, mods, plugins, security.
- Can run any mod or plugin you want.
- Requires more technical knowledge.
For most families with kids under 13, Realms wins. Mojang-side moderation removes the most common safety risks. Backups are automatic. You don't have to learn server admin.
For families with older kids (14+) or for tech-comfortable parents who want more control, an SMP is a better deal long-term.
Section 2: The Realms pricing math
Realms Plus (Java): $7.99/month, 10-player slots, Marketplace content included. Realms (Bedrock): $7.99/month, 10-player slots; 2-player tier at $4/month. Annual discounts roughly 15-20% if you pay yearly.
The 2-player tier is a trap for most families. Pay for the 10-player tier from the start.
Section 3: Whitelist management
A Realm is whitelist-only. Only invited players can join. This is your single most important moderation tool.
The Greg approach:
- Kid asks to invite a friend.
- Friend's parent gets a text from you: "Hey, [your kid] wants to invite [friend] to our family Minecraft server. Cool with you?"
- Friend's parent confirms.
- You add the friend to the whitelist.
- Friend's parent gets a text again two weeks later: "Anything weird? All good?"
This sounds like a lot of work. It is. It's also the only way I know to keep the whitelist from sprawling into a server full of strangers' kids.
Section 4: Backups
Mojang auto-backs-up Realms.
Trigger a manual backup before any major event. Examples:
- Kid is about to try a big redstone build.
- New player is joining for the first time.
- World update is rolling out.
- A friend with a history of trolling is logging on.
For really irreplaceable builds, download the world periodically to your own computer.
Section 5: Behavior rules that actually work for kids
- Don't break or take anything that isn't yours.
- No PvP unless everyone in the area agrees.
- TNT only in your own dig site or a designated TNT zone.
- If you find someone's stuff after they died, give it back.
- No copying redstone builds from YouTube without telling people.
- Mute or leave if someone is making the Realm bad.
- No talking about real-life addresses, schools, or full names in chat.
These get printed and taped near the computer in our house.
Section 6: Plugin alternatives for SMPs
- GriefPrevention — claim-based protection. Free.
- CoreProtect — undo log. Free.
- EssentialsX — quality-of-life pack. Free.
- LuckPerms — permissions management. Free.
- DiscordSRV — bridges Minecraft chat to Discord. Free.
The plugin combo I'd recommend for any first SMP: GriefPrevention + CoreProtect + EssentialsX.
Section 7: Do you really need a Discord for the Realm?
Probably not.
If you do create a Discord:
- Make it locked to the same whitelist as the Realm.
- One channel only at first.
- Parents are in the server.
- No DMs allowed between kids on the server.
- Pinned message with the rules from Section 5.
If you can avoid the Discord, avoid it.
Section 8: When to upgrade hosting tier
Signs you've outgrown Realms:
- More than 10 players.
- You want mods or plugins.
- You want to host friends' kids whose parents pay you a few bucks each.
The migration path: Realms → small SMP host (Apex, Bisect, Shockbyte) → self-hosted on a home server.
Common mistakes
- Buying the 2-player tier to save money.
- Inviting kids without checking with their parents.
- Skipping manual backups before risky events.
- Making the rules abstract. "Be nice" doesn't help a 9-year-old.
- Setting up Discord before the Realm needs it.
- Over-installing plugins on SMPs.
- Leaving the Realm running 24/7 without moderation.
A closing thought
A family Realm is one of the best things you can give a kid who's serious about Minecraft. It's their place. It's where they build a thing and come back the next day to find it still standing. It's where they learn that other people in their world have their own stuff that deserves respect. That's worth $8 a month and the moderation overhead.
