The air in the small, dim apartment was heavy with the hum of a custom-built rig that had seen better days. Leo sat hunched over the keyboard, the blue glow of his monitor illuminating a face etched with a mix of determination and fatigue. In the bottom-right corner of his screen, the persistent, translucent watermark mocked him:

Leo watched as the watermark vanished into the desktop wallpaper. The "Personalize" settings, once greyed out and locked, suddenly burst into color. He breathed a sigh of relief, not just because the task was done, but because the machine was finally, fully his. He leaned back, the blue light of a "genuine" Windows 8.1 Pro reflecting in his eyes, and began to render. technical breakdown

The rest of it

Everything the big IDEs have. None of the weight.

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. The air in the small, dim apartment was

Py

Python, ready to go

Custom interpreter settings, built-in documentation, instant execution. Scripts and automation without the setup tax.

Pin

Pin to front

Keep a scratch window floating above everything while you work in the app you're really debugging.

PNG

Share as image

One shortcut turns any snippet into a shareable image — syntax highlighting, window chrome, the whole thing.

What developers say

People who live in it.

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.
