Desktopfreeglobal

WizardJS is a free, open-source JavaScript and TypeScript playground for real-time code execution, built as an alternative to the commercial app RunJS, with multiple themes and customization. It's built for developers who want a fast, local scratchpad for trying out JS/TS code without setting up a project or paying for a playground app.
