What You Get

• Full syntax highlighting via Tree-sitter
• Code completion and error detection through typescript-language-server
• Run your code instantly - Bun handles execution
• Works on macOS and Linux (yes, your JS runs in Linux containers too)
• Automatic Bun installation - if you don't have it, Notepad.exe sets it up for you

Why Bun?

Bun is ridiculously fast. It handles syntax checking during builds, runs your code in the terminal, and works seamlessly with the TypeScript language server for intelligent code features. No Node.js configuration headaches, no npm setup dance.

Same Philosophy

Just like Swift and Python before it - zero setup. Open a note, write JavaScript, hit run. That's it. The toolchain downloads automatically if needed. You don't have to think about any of it.

Now you've got Swift, Python, and JavaScript all in one lightweight editor. Pick your poison.

Why This Matters

Developing for Linux on a Mac has always been... let's call it "not fun." You either SSH into a Linux box, manually manage VMs, or give up and use a separate Linux machine for testing. This applies whether you're writing Swift for server-side development or Python scripts for Linux deployment.

Not anymore. Now you write your Swift or Python code in Notepad.exe and hit run. Behind the scenes, everything is handled automatically - cross-compilation for Swift, virtual machine management, Linux execution. You don't see any of it - you just see your code running on Linux.

What Actually Works

• Cross-compilation - Build Swift projects targeting Linux right from macOS
• Automatic setup - Swift toolchains and Linux SDKs download and install when needed
• Real Linux execution - Your code runs in actual Linux environments with smart caching
• Python on Linux - Not just Swift - Python scripts can run on Linux too
• Full code intelligence - Code completion and error detection work for Linux projects

Platform Awareness

The notes library now shows which platform each note targets. There's a new platform column with icons for macOS, iOS, and Linux. You can filter, sort, and manage your notes by platform. The SDK browser lets you manage Linux SDKs alongside your macOS and iOS toolchains.

It's the little things. When you're juggling code across three platforms, you need to know at a glance what's what.

What This Enables

Server-side Swift development without leaving macOS. Python scripting for Linux deployment. Cross-platform testing without maintaining multiple machines. Prototyping Linux deployment while working in your comfortable Mac environment. Learning platform differences by running the same code on macOS and Linux side-by-side.

It's what I always wanted cross-platform development to feel like - whether you're writing Swift or Python.

Version 1.4 is available now. If you've been waiting for proper Linux support, this is it.

Another big step in 1.3 is App Distribution. For the first time, you can export a fully functional macOS application right from Notepad.exe. It's the first version of this feature, and already powerful enough to package up your work into something you can run and share on your own machine.

I also improved support for Swift and Python. You can open, edit, and highlight those files with better clarity, and even update packages without leaving the app.

On the personal side, themes got an upgrade. You can choose from more built-in styles or load your own. And if you like to tweak every detail, you can even swap the app icon right from settings.

The rest of 1.3 is all about polish: a cleaner interface, smarter text handling, better troubleshooting tools, and a long list of fixes for little annoyances.

For me, this release marks a shift: Notepad.exe is starting to feel less like just an editor and more like a coding companion - one that can now even build apps for you.

Grab it now at notepadexe.com. And if you've got feedback, drop it on the public issue tracker - I'd love to hear from you.

Fine. You win. 🐍

What's New

• Write Python. Run Python. That's it.
• pip stuff works (numpy, pandas, whatever you need)
• Output shows up instantly, like it should
• No virtual environments to mess with

Look, I get it. Sometimes you need to quickly parse some JSON. Or maybe you're prototyping that data thing before building the real version in Swift. Or you just like snakes. Whatever. Now you can do it without opening another tool.

But Why Though

I was debugging some server logs last week. Needed a quick Python script to parse them. Opened PyCharm. Waited. Created a project. Set up the interpreter. Configured the... you know what? Screw it. I added Python to Notepad.exe instead.

Took me three weeks of coffee-fueled coding sessions. Worth it? When I can switch between Swift and Python in the same window without any setup BS? Yeah, actually.

Swift Still Lives Here

Before anyone panics - Swift is still the main thing. iOS simulators, SwiftUI, all that good stuff. Python just moved into the spare room. They seem to get along fine.

What Actually Works Now

You can build SwiftUI stuff (with improved SwiftUI support), mess with UIKit, or try whatever iOS API you're curious about. Same zero-setup philosophy as always - just write code and hit run.

The simulator spins up automatically. No configuration, no project setup, no wondering if you forgot to check some box in Xcode. It just works.

About Tomorrow...

WWDC25 starts tomorrow. Not gonna lie, the timing worked out pretty well.

While everyone else is creating new Xcode projects and fighting with build settings to try the new APIs, you can literally just open a note and start experimenting. That's... actually kind of nice.

Quick Thanks

Before I forget - thank you for the ongoing support since the first launch. Your feedback has been incredibly helpful, and I've been squashing bugs based on what you've reported. Keep it coming - it's making Notepad.exe better for everyone.

So Many Fixes and Improvements

Honestly, there are so many bug fixes and improvements in 1.1 that I can't list them all. The AI integration got better, SwiftPM support is more solid, and a bunch of other stuff too. If you tried Notepad.exe before and it wasn't quite right for you, maybe give 1.1 another shot.

iOS runtime was the most requested feature by far. If you've been holding off because "macOS only" wasn't enough, well... now it's not macOS only.

Have you ever wanted to quickly test a Swift idea without firing up Xcode and creating an entire project? Or found yourself needing a lightweight environment to experiment with code snippets that you could organize and reference later? That's exactly why I built Notepad.exe - to bridge the gap between heavyweight IDEs and basic text editors.

What Makes Notepad.exe Special?

• Swift-First Approach: Everything is optimized for Swift, from code completion to syntax highlighting
• Library-Based Organization: Your snippets live in a searchable, taggable library that makes finding past work a breeze
• Floating Notes: Pop out your notes to hover above other apps - perfect for referencing code while working elsewhere
• Swift Package Manager Integration: Import and use external packages directly in your snippets
• Local AI Assistance: Get helpful code suggestions while keeping your code private - all processing happens on your Mac
• Tear-off Sticky Notes: Create quick throwaway notes that stay out of your library when you need them
