Still there when you get back.

Yes, but not in the way the phrase is usually used. Several hosts now advertise AI assistance and mean a chatbot in the billing panel that helps you configure the server. Cog is an AI agent inside the game itself: it stands in the world, builds what you describe, mines alongside you and writes new games into the world while you are playing in it.

You do not choose. Every plan is sized by how many people play, not by gigabytes, and the world is given what it needs to run the builds and games on it. Most hosting makes you guess at RAM up front and then upgrade when it stutters; there is nothing here to guess at.

Yes. It is always on, whether or not anybody is playing. That is the point of hosting it rather than running it on a laptop — Cog can be halfway through a build when you go to bed and finished with it when you get up.

Yes. The world is backed up on a schedule without anybody asking, any backup can be restored, and the whole world can be downloaded at any time. It is your world; if you leave, you take it with you.

No. Cog runs on the server, not on anyone’s computer, so your friends join with an ordinary, unmodified copy of the game. They add your server the way they would add any other.

No. The world runs on a hosted server, so there is nothing to configure at home and no router settings to touch.

The world keeps running. It is not on your machine, so turning your computer off does not turn the world off. Cog can be mid-build when you go, and finished when you come back.

Yes. Run it whitelist-only and it accepts nobody except the players you have named.

Yes, by the same rules you do. Ask Cog to follow you, hold the base while you go exploring, or go and turn iron ore into armour, and they gather and craft the materials rather than conjuring them.

Yes. Name a modpack on CurseForge or Modrinth and the version you want, and your world is built on it — with Cog standing in it, able to build with everything the pack added.

Yes, and properly. Cog asks your server what your mods added the moment they join, so they can name those blocks, mine them, carry them and build with them — and craft the mod recipes they have never seen, by asking the server for them. This works without any support for your particular mod and without anything installed on your server.

Yes. Copy your world into a second server and wreck it — real terrain, real builds. When the game you were testing is right, move it across to the world your friends are on. No copying files by hand.

Yes. Upload the save — from the server you are on now, or the single-player world you have been building since Christmas — and it comes up running with everything where you left it. If it was built on a modpack, the pack comes with it.

Yes. It is your save, in the same region files any Minecraft server writes — open it in single player or take it somewhere else entirely.

Yes. Some people want a server that stays up and nothing else. It is the same hosting — your own world, always on, whitelist, backups, downloadable — with nobody in it but the people you invite. It costs less, and you can add Cog later without moving worlds.

Yes, and it is pinned until you do. A world does not get quietly updated underneath your builds because a new release came out.

Minecraft Java Edition. Hytale is next — it entered Early Access in January 2026 and was built for exactly this kind of thing.

Cog tells you, because they measure their own work. Creative-mode builds can be undone, and worlds are backed up on a schedule. See Verification and Safety for the detail.
