Mirg is a desktop app where an AI agent writes your game, runs it, and plays it to check that it works. When you like it, one click turns it into a link anyone can play, on a computer or a phone.

A demonstration using a real game made with Mirg. · Play this game yourself
These are two examples. Mirg builds any kind of game, 2D or 3D, and also works with Godot, Unity, Unreal Engine, Roblox, Minecraft, Ren'Py, Python, LÖVE and GameMaker. See every platform
How it works
No engine to learn and nothing to set up. If you can describe it, you can start.
Say what you want
Type it or say it out loud. "A platformer where a fox collects coins and avoids spikes." That is enough to begin.
The agent does the work
It writes the code, starts the game, looks at the screen and presses the keys itself to make sure things work before telling you it is done.
Keep going
Play it right there. Ask for a double jump, a new enemy, real artwork. Every message has a Restore button, so nothing is permanent.
One click, one link
Press Share and get a link anyone can open to play, on a computer or a phone. Nothing for them to install. Put it on mirg.ai too, if you like.
What makes it different
Most AI tools hand you code and hope. Mirg runs the game and checks its own work.
It plays what it builds
The agent takes screenshots, presses keys, taps the screen and reads the score, then fixes what is broken. It also tells you what it could not check.
The game is always in front of you
Game in one tab, code in another, files and art in a third. Look under the hood only if you want to.
Phone games included
Preview on an iPhone or Android screen with real touch input, then turn the game into an app that runs in the iOS Simulator or Android emulator.
Ship it as a link
Other tools stop at code on your computer. Mirg ends with a game people can play: one click gives it a link, its own preview picture when you post it, and a play count.
Pick your model
Claude, GPT and Gemini models, with a simple control for how hard the model thinks. No API keys to manage.
Your files, on your computer
Projects are ordinary folders on your Mac. Open them in any editor, put them in version control, take them anywhere.
Works with the engines people use
Web, phone and Godot games play inside Mirg, where the agent can see and test them. Other engines work if you have them installed, and Mirg tells you what is missing and how to get it. Every one below has been run for real.
