For solo game developers · Early access

You are the studio.
Castforge is the rest of the team.

A one-person game studio on your desktop. AI agents plan the game, write the code, make the art, animate it, add the effects and the sound, then help you ship. Connect the AI you already use.

How a game gets made

One pipeline, from idea to release.

No more copying prompts between five tools. Each step hands its work to the next one, and you approve what matters.

01

Plan

Pitch the idea. The Lead writes the game bible, the style guide and a plan you can steer.

02

Code

Gameplay and systems get built, reviewed and tested, phase by phase.

03

Art

Concept art, textures and 3D models, all held to the look you chose.

04

Animate

Characters get rigged and animated, and each pass gets checked frame by frame.

05

VFX

Hits, spells, dust and sparks that match your style.

06

Audio

Voices, sound effects and music, generated and placed.

07

Playtest

The build gets played and compared against your target look, round after round.

08

Ship

Builds, store pages and release notes, ready for your review.

Works with Unreal Engine
Your AI, your machine

Works with the AI you already use.

  • You pay your provider directly. Castforge sells the workspace, not the model.
  • Your project stays yours. Everything lives on your machine, in your own files.
  • You stay in charge. Choose how often the team asks before it acts.

Not only games

The same studio builds apps and websites.

Switch a project to App or Web and the team picks up the right tools. Games come first, but the studio is not limited to them.
