Everything a small MMO needs

Host in minutes

The launcher creates a world, starts it and shows its address. No terminal, no router admin page.

Invite with a code

Friends type eight letters. They connect straight to you when they can, and through the MMO Run relay when your router is in the way.

Classic MMO in a box

Five classes, abilities, mobs, loot, quests, NPC dialogue and vendors, ready the moment the world starts.

Point and click

Click to walk, click an enemy to fight, right-click to cast. Path-finding takes you around walls and water.

Turn features on and off

Guilds, trading, crafting, housing, pets, mail, day and night: every system is an extension you can enable and tune.

Your data, your machine

A world is one folder with one database file. Copy it to back it up. Nobody else holds your players' accounts.

How it works

  1. 1

    Create a world

    Pick the Classic MMO preset, a name and how many players. Press Start.

  2. 2

    Make it yours

    The first account becomes the owner. Press F2 in game to open the editor.

  3. 3

    Invite friends

    Press New invite, share the code, and they join from desktop or phone.

Build it from inside the game

Paint terrain, drop props and portals, move spawns and resize zones with a live preview. Save, and the zone rebuilds for everyone standing in it.

NPC dialogue edited as a node graph

Quests, dialogue and scripts

Write NPC conversations as a node graph, build quests from forms, and add world events in Run Script: a few readable lines with conditions, choices, flags and timers.
