Write SwiftUI.
Run it live.
A native SwiftUI playground for Mac. Write a component, watch it run live, share it with the community.
Every post is real SwiftUI.
Every post runs natively on your Mac, at full screen or phone size, in light or dark. Open the source and it pastes into Xcode as plain SwiftUI.
Change a line.
Watch it move.
Edit the file and hit Run, or ask Claude Code or Codex to make the change. Swoop checks the code against its real player and shows the result right away, without an Xcode project or a simulator.
A feed made of components.
For You surfaces what's new and taking off, saves every fifth slot for a post under three days old, and learns from what you like and follow. Open the source of anything, fork it, make it yours.
Works with the AI
you already use.
Swoop has a built-in MCP server, so Claude Code, Codex and other MCP clients can build in it on your existing account. Connect one from Settings with a single command.

FAQ
Swoop
What can it run?
One SwiftUI component per project: views, shapes, paths, gradients, TimelineView and PhaseAnimator animations, gestures, @State and the math you need. It isn't a full app compiler: no ScrollView, List or navigation stacks.
Do I need an AI subscription?
No. You can write everything yourself. If you use Claude Code or Codex, Swoop connects to them over MCP and uses your own account.
Where are my projects stored?
On your Mac. Nothing is uploaded until you publish a post to the community.
Is there an iPhone app?
Yes. Swoop on iPhone is for browsing and playing what people make. Building happens on the Mac.
Buying
Is Pro a subscription?
No. You pay once and keep Pro forever, including every Pro feature we add later.
How does the price work?
The first 10 licenses are $5, the next 20 are $10, the next 40 are $20 and the next 80 are $40. After that it stays at $69.99. You pay the price shown when you start checkout.
How many Macs can I use?
All of them. Pro belongs to your Swoop account, so it works on any Mac you sign in to.
