    VSCodium

    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

    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.
