Multiplayer AI app building
AI app building just went multiplayer.
Describe an idea and Forge ships a real app. Then bring builders into the same project — everyone building at once in parallel lanes, each with their own Forge AI, merging verified work into one product. Every other AI builder is single-player. This one isn't.
idea → teammates → product → momentum
The multiplayer system
One app. Many builders. Every one of them shipping with AI — at the same time.
One project. Everyone in it, live.
Presence, shared build chat, and live intent — you see who's building what before they ship it, not after.
three builds, at the same time, one app
Everyone builds at once — in lanes.
Each builder takes a lane with their own Forge AI. Lanes are real branches of the app, so nobody waits and nobody overwrites.
Nothing lands without proof.
Forge AI pre-reviews every lane, verification runs the app, a human approves — then it merges into Main with everyone credited, permanently.
Not a shared cursor. Lanes are real branches of a real app, merges are AI-reviewed and gated on verification that ranthe code, and credit is stamped into the project's history — permanently.
What will you build?
If it runs in a browser, Forge builds it.
Real, runnable apps from a single prompt — games included. Each of these is one sentence away:
3D games
one prompt“Let's make a 3D Minecraft video game. I need at least 60 FPS.”
SaaS & dashboards
one prompt“An analytics dashboard with live charts and filters.”
Storefronts
one prompt“A storefront for my art prints with a cart and checkout.”
AI apps & copilots
one prompt“A support copilot that answers from my docs.”
Team tools
one prompt“A kanban board for our sprint with drag and drop.”
Trackers & planners
one prompt“A habit tracker with streaks and a weekly view.”
Idea to product
Describe it. Forge builds it.
Tell Forge what you want and get a real, runnable app you can use right now — published to your own GitHub repo, then shaped move by move with Forge AI until it's exactly what you had in mind.
- Real, runnable apps — React, Vue, Svelte, backends
- Yours, in your own GitHub repo
- Runs live — preview or a backend sandbox URL
- Fast, Smart, Genius, or Max build depth
Remix & reputation
Reputation you can't fake.
Publish Open Source and other builders remix your work — building on top of what you shipped. Your standing comes from what people actually build on and use, plus verified GitHub commits — not likes you can farm.
- Remix anyone's Open Source app
- “N builders built on this”
- Reputation from real, engaged usage
- Verified GitHub commits

You choose what's shared
Your identity is built from real build history — not a profile you maintain. Private projects never appear in public.
- Private
- Just you and Forge AI. Your build history stays personal.
- Public
- Your progress is visible. Builders follow, discover, and ask to join.
- Open Source
- Everything in Public — and contributors build alongside you.
Start the build. Bring your crew.
Describe an idea, ship a real app, and build it with people — not alone in a chat window.
