You already know what it should be, whether it's a game you've been sketching in your head or a tool you wish existed. Wundur Studio puts an AI coding agent to work on it, in a window made for watching your idea take shape, with your project right beside the conversation.
The models make the pieces. The art is the world you put together.
Why it exists
An AI agent can now write much of the code that turns an idea into something real. Following along is another matter. In a terminal it all scrolls past as one long log, and a few minutes in it's hard to tell whether what's being built is still the thing you meant.
Wundur keeps your idea in view. The conversation, what each turn changed and the project it all goes into share one window, so you can see it coming together and steer before it drifts. It runs the agent you already use, exactly as it ships, and never rewrites what the agent does.
When it needs art and sound
A game needs more than code. With Wundur's game-assets pack, the agent can make images, sound effects, voices and music, and 3D models it can rig and animate. You can turn a model around in a viewer beside the chat before you keep it. Everything lands in your project as ordinary files, ready for whatever engine you use.
The pieces come from AI image, sound and 3D services that you connect with your own keys, and Wundur asks you before every run that costs money. They're AI-made, and you decide which ones stay.
While it's being built
Some steps are yours: signing in somewhere, accepting an agreement, adding a secret, trying the game on your phone. Instead of burying them in a long reply, the agent hands them to you as numbered cards, each with the command to copy and the page to open. Tick them off as you go; the agent can see what's left and tick off the ones it checked.
When the agent has questions, they come one at a time as a card, each answer with what it means. When it wants to run a command, the chat shows the exact command with Allow and Deny. The session is marked Needs you in the list, and the Dock icon bounces once if you're looking at something else.
Agents can send you a notice when something is done or needs a decision, and the inbox keeps them for you across every session and project. Questions still waiting are at the top. A notice that asks something comes with its answers as buttons, or write your own reply, and it goes straight back to the agent that asked.
The New session screen starts from a folder. Pick one, name the session if you like, choose the agent, and tick a box to work in a new git worktree. The folder's previous sessions are listed underneath: resume one, switch to one that's already open, or fork it into a new session. Sessions gather under their project in the list, and Cmd+P jumps to any of them by name.
One panel lists every skill the agent can load, from the project, your home folder and installed plugins. Open one to read it beside your work, or edit it in place.
A file tree, an editor with syntax highlighting and go to definition, and real terminals share the window with the session. When something looks off, open the file and fix it. Panels dock and split by drag and drop.
Settings is a page in the window, with a search box. Choose light or dark, a tab style, and any Google Font for the app, the chat and the terminals. MCP servers and your own command-line tools are set up once and every agent gets them. Terminals, notifications and turn summaries each have a page too.
Where it stands
Open source · Apache 2.0
Wundur is written in Rust on gpui, the framework behind the Zed editor. There is no browser engine inside, so it opens quickly and stays small.
It started as one developer's own tool. If it helps you build what you're picturing, issues, ideas and pull requests are welcome.
