How it works

One line in, a playable build out.

  1. 1

    Describe it

    “3D platformer, collect coins, lava rises.” It asks three questions back, at most.

  2. 2

    The crew plans

    A design doc, a task list and a style guide, all in one project brain.

  3. 3

    It gets built

    Scenes, scripts, menus, pause and a win screen, using assets from the studio.

  4. 4

    A bot plays it first

    Compile, tests and a playtest have to pass before you ever see it.

FAQ

Fair questions.

Something missing? Ask us on X.

Which engines does it support?

The studio builds games that run right in the browser. Plugins bring it into Unity, Roblox Studio, Blender and Unreal. The game builder starts with Unity; Roblox Studio follows from the same game description.

Do I need to know how to code?

No. The agents write the code. It’s still your project, so you can look at everything and change it anytime.

What will it cost?

Prices aren’t final yet. The studio runs on credits; the local game builder is a paid plan that runs on our keys. The pricing preview shows the current idea.

When can I use it?

The Unity package works today with your own agent. Synagy for Minecraft is in closed beta: join the waitlist for early access, and buy within your first 14 days to get 500 bonus credits on top.

Who is behind Synagy?

Two people, building it in public on X and TikTok.
