Open a file. Hit ⌘R. Done. No project setup, no config files. A lightweight IDE for developers who want to code, not configure.
No New Project → Configure → Wait → Finally Code. Just code. Swift for iOS and Mac apps, Python for scripts and automation, JavaScript for web projects — all in one window that launches instantly.
Open a file, hit run, see output — no project wizard, no indexing, no waiting. When the scratch turns serious, settings unlock the advanced setup: custom interpreters, build flags, targets.
Local AI processing, privacy-first. Your code never leaves your machine. Completions, refactors, and explanations from a model that runs on-device — not in someone else's data center.
Prototype SwiftUI and UIKit screens. Test APIs. See your app on a real iPhone bezel without ever opening Xcode.
Run executables on macOS or Linux — the Linux subsystem installs itself. Recipe and oven, no kitchen remodel.
Run Python with custom interpreter settings and built-in documentation. Organize scripts in the Notes Library. Pip deps via a simple requirements panel.
Native performance, no splash screen, no indexing. Here's what's in the box.
Prototype SwiftUI and UIKit screens — test APIs in the Simulator without ever opening a project file.
Edit and run SwiftPM packages directly. Target macOS or Linux — the Linux subsystem installs itself.
Build SwiftUI applications with animations and interactive UI. Export a .app when you're ready.
Custom interpreter settings, built-in documentation, instant execution. Scripts and automation without the setup tax.
Keep a scratch window floating above everything while you work in the app you're really debugging.
One shortcut turns any snippet into a shareable image — syntax highlighting, window chrome, the whole thing.
Swift developers who got tired of waiting for Xcode to finish indexing.
I really dig the Notes Library and the ability to pin a window to the front. Cot does too little for me, Xcode is overkill for small things so I really love this.
It's an excellent small code editor to explore all your Swift ideas without launching a heavy IDE like Xcode. The option to create an image for sharing code is just perfect!
I was really impressed with the performance, only to learn Notepad.exe is a native app. Where Xcode playground has to work despite Xcode's years of legacy, Notepad.exe has a very promising future.
It's fast, lightweight and refreshingly low-friction — allowing one to jump straight into experimenting with code snippets. It's exactly the Swift playground we've all been wanting.

Both! It's a lightweight IDE with code completion, live error detection, and instant execution — without the bloat. Think Xcode Playgrounds done right.
I like to live dangerously.
We've got Swift, Python, and JavaScript covered. More languages? Maybe. Stay tuned!
Works with just Swift Toolchain, but having Xcode's SDK lets you run applications. Like having both the recipe and the oven!
Yes, it runs iOS code now. You can build SwiftUI apps, work with UIKit, or experiment with any iOS API using the built-in iOS Simulator integration.
No, but there's an app named kindaVim that is 100% compatible, and I recommend it!
It might transform into one after midnight. Who knows? Check out swiftstudio.app.
For very mysterious reasons, like protecting the last piece of grandma's secret pie recipe. Plus, parts are open source on GitHub, so I'm not a total villain!
