NetPad
NetPad is a cross‑platform C editor and playground that lets users write, run, and test C code instantly without creating a full project. It runs as an Electron or Tauri desktop app or in a browser and requires only the .NET SDK. Key features include immediate execution of code snippets, interactive data visualization, LINQ and SQL database querying, learning and experimenting with new C language features, and saving utility scripts. Typical use cases are rapid prototyping, algorithm testing, exploring language capabilities, building small utility tools, and performing quick data analysis.
