fragA better server experience, without the server.
The mod itself. Your machines run the world and your storage keeps it.
Download the modWe hold the world off-site as an ordinary Minecraft save, so it is still there when nobody has played for weeks.
Create an accountFragments is a Minecraft mod. Install it and your group runs the world between you, so there is no server to rent. Joining is still a link and a row in the server list.
The evening you already know.
A link in the chat, a row in the server list, a whitelist saying who gets in. An evening here works the way server evenings always have, and it goes differently in three places.
When the last of you logs off, the world stops running and stops costing anything. Come back a fortnight later and the save is waiting. A rented server keeps the save too, and bills you for the two idle weeks.
One link, and they’re in
They paste it into Add Server and the world sits in their server list from then on. The pack and its size are shown before they commit, and accepting restarts them straight into it. The whitelist decides who is let in, so the link is safe to paste into a group chat.
The pack runs on everyone’s machine
A pack this heavy means an 8GB plan or better if you’re renting one, sized and paid for up front whether you fill it or not. Here the work is shared across whoever is online, so no single machine has to carry the whole pack.
Someone quits mid-flight
The regions they were hosting pass to whoever is standing in them. The switch takes under a second, and nobody else's game is interrupted.
Priced by how much memory your pack needs, billed around the clock, and when it breaks, everyone sets the pack up again by hand.

Built for the heaviest packs.
The heavier the pack, the bigger the difference, because rented prices scale with memory and ours don’t.
Rig-validated · n=1, single machine — not projections. Wire figures and the rest of the mechanism →The size of pack that needs a 16GB plan on a rented host. Here it runs across the group’s machines, so there is no plan to buy.
A ridden, four-body flying ship crossing an authority border, handed over in ~3.2 s. Moving physics is the hardest case to keep in sync, so it is the one we measure.
Two ways to keep a world.
The mod runs the world across everyone's machines either way, at the same speed, with the same pack. The difference is only where the saved copy sits when nobody is playing.
Free while Fragments is in closed beta. There is nothing to buy, no card anywhere on this site, and no ads. If that ever changes we will say so clearly, and well before it does.
