Cobble

Cobble builds a modded Minecraft world for you and your friends. It checks every mod it downloads, then starts the server and waits until the world answers. Only then does it say ready.

What it does

  1. Finds mods

    Searches for mods that match your version and loader, and tells you where each one came from.

  2. Builds the pack

    Downloads them and checks every file against the hash the source published. A file that does not match is not used.

  3. Asks the world

    Starts the server and waits until it answers a real ping. Only then does it say the world is ready.

What it costs

Playing on the same wifi is free and always will be. Letting a friend in a different house join is free too, for now.

  • Free no account

    Everyone on the same wifi can join. Nothing to pay and nothing to sign up for.

  • Free an account, one world

    Friends anywhere can join, one world at a time. A grown-up sets the account up with an email address. No card, and none is asked for.

Relays are free while Cobble is early. When that changes it will be a term with an end date — not a subscription, nothing that renews on its own, and nothing that charges a card Cobble was never given.
