VSCodium
binary releases of VS Code without MS branding/telemetry/licensing
Microsoft’s vscode source code is open source (MIT-licensed), but the product available for download (Visual Studio Code) is licensed under this not-FLOSS license and contains telemetry/tracking. The VSCodium project exists so that you don’t have to download+build from source. This project includes special build scripts that clone Microsoft’s vscode repo, run the build commands, and upload the resulting binaries for you to GitHub releases. These binaries are licensed under the MIT license. Telemetry is disabled. If you want to build from source yourself, head over to Microsoft’s vscode repo and follow their instructions. VSCodium exists to make it easier to get the latest version of MIT-licensed VSCode. Please note that some Visual Studio Code extensions have licenses that restrict their use to the official Visual Studio Code builds and therefore do not work with VSCodium. -

Notepads
A modern, lightweight text editor with a minimalist design
I have been waiting long enough for a modern Windows 10 notepad app to come before I decided to create one myself. Don’t get me wrong, Notepad++, VS Code, and Sublime are great text editors. I have used them all and I will continue to use them in the future. However, they are either too heavy or look less appealing. There are times that I just wanted to use Windows Notepad for things like writing notes or editing config files. So I decided to create a win32 notepad replacement here and try to give it a modern look and feel. Most importantly, it has to be blazingly fast and appeal to everyone. -

Monaco Editor
A browser based code editor
Monaco Editor is the rich, browser-based code editor that powers Visual Studio Code, providing advanced editing capabilities as a standalone embeddable library for web applications. Models are at the heart of Monaco editor. It's what you interact with when managing content. A model represents a file that has been opened. This could represent a file that exists on a file system, but it doesn't have to. For example, the model holds the text content, determines the language of the content, and tracks the edit history of the content. An editor is a user facing view of the model. This is what gets attached to the DOM and what your users see visually. Typical editor operations are displaying a model, managing the view state, or executing actions or commands. -

UIkit
Lightweight modular front-end framework for developing web interfaces
A lightweight and modular front-end framework for developing fast and powerful web interfaces. UIkit will work on pretty much any modern browser. Using UIkit works best if you have a solid code editor, for example Sublime Text or Atom. To be even more efficient, we recommend that you install one of the autocomplete plugins for your favorite IDE or code editor. This saves a lot of time, as you won't have to look up and type all UIkit classes and markup. To use UIkit's CSS and JavaScript, include the files in your own HTML and then create the markup of any of the components. When you have installed UIkit with Less sources, you can compile it and add your own custom theme. Less is the language that the UIkit styles are written in. This allows you to include customizations in the build process, rather than manually overwriting a lot of CSS rules by hand. -

Atom Beautify
Universal code formatting plugin
atom‑beautify is a universal code formatting plugin for the Atom text editor, offering support for numerous languages and formatter engines to clean or prettify source code. Many users are experiencing issues when installing third-party beautifiers (e.g., Uncrustify, PHP-CS-Fixer, and many more). A possible solution is a "cloud" service that provides remote access to these beautifiers. Atom-Beautify would then communicate with these services, allowing for zero-installation beautification. Some of the supported beautifiers are developed for Node.js and are automatically installed when Atom-Beautify is installed. However, other beautifiers are command-line interface (CLI) applications and require you to manually install them. -

CodeEdit for macOS
Elevate your code editing experience. Open source, free forever
CodeEdit is a code editor built by the community, for the community, written entirely and unapologetically for macOS. Features include syntax highlighting, code completion, project find and replace, snippets, terminal, task running, debugging, git integration, code review, extensions, and more. Developers that use a Mac should be able to use an editor that feels at home on the Mac. Comparable editors are built on Electron. This is a huge limitation because it cannot utilize system resources to their fullest potential. Electron requires a Chromium instance to run. This can mean massive performance losses and high RAM usage even for small apps built on it. Additionally, the overall code footprint is much larger and animations are slower. More frames are lost and things like window resizing feels laggy. Native apps are smooth as butter and utilize system resources much more efficiently for better performance and reliability. -

Runestone
Performant plain text editor for iOS with syntax highlighting
Performant plain text editor for iOS with syntax highlighting, line numbers, invisible characters and much more. Runestone uses GitHub's Tree-sitter to parse code to a syntax tree which is used for features that require an understanding of the code in the editor, for example syntax highlighting. Highlight ranges in the text view. Search the text using regular expressions. Automatically detects if a file is using spaces or tabs for indentation. Specify line endings (CR, LF, CRLF) to use when inserting a line break. Automatically detect line endings in a text. When judging the performance of Runestone, it is key to build your app in the release configuration. The optimizations applied by the compiler when using the release configuration becomes very apparent when opening large documents. The project should mostly work with Catalyst on the Mac, however, it isn't fully tested and the implementation isn't considered done. The focus is currently on the iPhone and iPad. -
