Test your C# code online with .NET Fiddle code editor.

Visit .NET Fiddle

.NET Fiddle is an online code editor and playground that lets developers write, run, and share .NET code directly in the browser, without a local development environment. It provides a workspace for creating and editing files and folders, running code, and viewing results, which is useful for testing snippets, experimenting with language features, and sharing examples with others.

The editor includes actions for saving, forking, running, and sharing fiddles, along with collaboration, a tidy-up option, and a View IL mode for inspecting intermediate language output. File management tools cover creating new files and folders, renaming, copying paths, and deleting items. A Getting Started guide, a Chrome extension, and a roadmap are also listed among the available resources.

Users can sign up or log in to an account, and the interface includes links to support and contact options. The pages do not state a free plan, trial, editions, or seat-based or usage-based packaging.
