AI app builder for macOS
Build the app you want, not just what you need.
The Forge handles the hard parts of vibecoding — writing the spec, tracking the features, and building the code with AI — all in one window, all on your Mac.

How it works
From an idea to a running app without leaving one window — and without you writing the boilerplate.
01
Interview
Answer questions about what you're building. The Forge locks a clear, versioned spec.
02
Build with AI
An in-app agent implements each feature against your repo, feature by feature.
03
Run & Preview
Launch it on a simulator or emulator and watch it live, with hot reload.
04
Ship
It updates your docs, commits, and pushes — then tracks what's next.
What it does
A project manager and a builder, in one.
Talk it through, get a spec
A guided interview turns a rough idea into a locked, versioned spec — with the LLM judging when each answer is actually clear enough to build from.
Build with AI
An in-app implementation agent writes real code into your repo — targeted edits, not full rewrites — gated on a clean analyze pass, streaming its work so you can watch.
A tracker that thinks
A feature board with AI tools built in: scan your repo for what exists, recommend what to build next, plan the build order into versions, and dedupe.
Run & Preview
Run your app on a simulator or emulator and watch it live inside The Forge — it even boots the simulator for you — with hot reload and the build console right there.
Architect the hard parts
It spots the features too big to one-shot, breaks them into properly sized sub-tasks, and refuses to fake work it can't do — like an ML model that needs a real dataset.
Yours, and private
Bring your own key — Ollama Cloud, Claude, or OpenAI. Your keys are stored encrypted in the macOS Keychain, the app is signed & notarized, and there's a built-in security check.
What you build with it
macOS
A native Mac app. Signed and notarized by Apple — no scary "unidentified developer" warning.
Flutter apps
Target iOS, Android, macOS, and web from one codebase — The Forge scaffolds, builds, and runs them for you.
AI key
Point it at Ollama Cloud, Claude, or OpenAI. You choose the models; you own the usage.
Pricing
Free. You bring the key.
The Forge is free — every feature, no account, no server. You connect your own AI key and pay your provider directly for what you build. We never see your usage or take a cut.
$0 · every feature
- No account, no sign-up.
- No Orbital AI markup — you pay your provider, not us.
- Your keys stay in your Mac's Keychain.
- Nothing to cancel — it's your key, your account.
What building costs
You pay your AI provider for the tokens a build uses — usually cents to a couple of dollars per feature. Run a cheap, fast model for most of it, and switch to a stronger one for the hard parts.
Managed — no key
A paid option where we run the AI for you: no provider account, no keys, one bill. For when you'd rather not manage a key. Not here yet.
Do I pay Orbital AI anything?
No. The app is free — you only pay your AI provider for what you build.
How much will building cost?
Usually cents per feature. You watch spend in your provider's dashboard, and a cheap cloud model keeps it low.
Which key should I get?
Any of Ollama Cloud, Claude, or OpenAI. Ollama Cloud is the easiest cheap start; Claude or OpenAI for top quality.
Are my keys safe?
They live in your Mac's Keychain and never leave your machine. No Forge server ever sees them.
Made for people building their first real app — and their tenth.
