Writing a little bit of code should not be a hassle. But most IDEs force you to set up a project, navigate layers of menus, and configure build systems before you can even type a single line. Notepad.exe flips that script. You start with a blank file, write your code, and figure out the project later.
This indie Mac app is built for developers who want to get ideas down quickly without the overhead of a full IDE. It supports Swift, Python, JavaScript, TypeScript, and Go out of the gate. Just write your code and hit run. If you decide to build something more substantial, you can turn it into a project afterward.
What makes Notepad.exe different
The app offers a native-feeling UI that resembles Xcode but without the bloat[reference:24]. It is designed for speed. Open the app, start typing, and run your code. No project creation wizards. No build configuration files. No waiting.
For developers who work with multiple files, Notepad.exe includes a Notes library that organizes your code snippets and one-off files. You do not need to remember where you saved that quick script from three weeks ago. It is all in one place.
The app also includes a built-in agentic coding assistant. You can connect your Codex subscription or use local models to troubleshoot problems in your codebase[reference:25]. This turns Notepad.exe into more than just an editor. It becomes a pair programmer that can help you debug, refactor, or explore alternatives.
One of the standout features for iOS developers is the ability to bring the simulator inside the text editor. If you are writing SwiftUI, you can see your changes in real time without switching windows[reference:26]. It is a small touch that makes a big difference in workflow.
Pricing and availability
Notepad.exe is available for download from the developer's website. The core experience is free with no account required. For the fully-featured experience, you can upgrade to Notepad.exe Pro, which costs 45 for a perpetual license covering all updates within version 1.x[reference:27].
The free version is generous enough for casual use. The Pro tier adds the coding assistant, simulator integration, and additional features that serious developers will appreciate.
Who this is for
Notepad.exe is not trying to replace Xcode or Visual Studio Code. It serves a different purpose. It is for the moments when you want to test an idea, write a quick script, or prototype something without spinning up a full project. It is for developers who value speed and simplicity over feature density.
If you have ever found yourself avoiding a coding task because opening your IDE felt like too much effort, Notepad.exe might be exactly what you need. It gets out of your way and lets you write code.
