What Developers Are Saying

Jakob's profile picture
I really dig the Notes Library and the ability to pin a window to the front. Love the included assist too. Cot does too little for me, Xcode is overkill for small things so I really love this. The website + the small yellow notes are so cute. We need more whimsical stuff. Thanks for making this!
Thomas Ricouard's profile picture
It's an excellent small code editor to explore all your Swift ideas without launching an heavy IDE like Xcode And the option to create an image for quickly sharing a piece of code on social networks is just perfect!
Sash Zats's profile picture
I was really impressed with Marcin squeezing every drop of performance from Electron, only to learn Notepad.exe is a native app. With Marcin's decades of experience building text components this lightweight IDE is great for putting together quick ideas to see what works. Where Xcode playground has to work *despite* Xcode's years of legacy, Notepad.exe has a very promising future ahead of itself
Konstantin's profile picture
I've tried loads of Swift dev tools, and Notepad.exe is one of the few that hasn't made it onto my naughty list. It's fast, lightweight and refreshingly low-friction - allowing one to jump straight into experimenting with code snippets without distractions or unnecessary side-quests. It's exactly the Swift playground we've all been wanting.

Notepad.exe Frequently Asked Questions

Q: How do I get Notepad.exe?
A: Download and purchase Notepad.exe or try the free version with core features. You can also subscribe to receive information about releases.
Q: Wait, isn't Notepad.exe the Windows Notepad? Why name a Mac app ".exe"?
A: You caught me! Yes, it's intentionally ironic - naming a native macOS app with a ".exe" extension is the kind of rebellious humor that makes developers smile (or groan). It's a playful nod to the simplicity of Windows Notepad while being the exact opposite: a powerful, native Swift and Python code editor built exclusively for Mac. Think of it as the ultimate plot twist in the code editor story. Plus, it makes for great conversation starters at tech meetups!
Q: When will you support language X?
A: Sooner than later. I'm starting with Swift, though, because I'm classy like that.
Q: Can't I just use (insert tool you have an opinion about)?
A: Sure, why not? Go ahead and be a rebel!
Q: (Tool you have an opinion about) does it better.
A: That's fantastic news! More power to you and your tool-wielding skills!
Q: Why?
A: Because I can... and also because unicorns told me so.
Q: Is this Swift Studio?
A: It might transform into one after midnight. Who knows?
Q: Why isn't it open source?
A: 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!
Q: I could build it over the weekend myself?
A: Go for it! Just make sure to send me a postcard when you're done.
Q: Why don't you just...?
A: Yes! Wait, what was the question again?
Q: It looks like CodeRunner with some AI sprinkled in?
A: Sure, and my toaster's a space shuttle. But hey, great detective work, Sherlock!
Q: Do I need Xcode installed?
A: Notepad.exe works with just Swift Toolchain installed, but having the SDK from Xcode allows you to run applications. It's like having both the recipe and the oven!
Q: Can I develop iOS apps with Notepad.exe?
A: I spent months adding iOS simulators just so you could ask this question. Yes, it runs iOS code now. Your iPhone apps can finally escape Xcode's loving embrace!
Q: Did anyone actually ask these questions?
A: Nope, but it feels good to pretend they did!
