Check out one of these example fiddles or create your own. For more code examples, check out the solutions gallery on developer.fastly.com.

Experiment, test, share, embed

In a fiddle you can do almost anything you can do in a real Fastly service, but there’s no need to sign up or log in. You can share your fiddles with friends and colleagues, even embed them on any website you like.

Most code examples on developer.fastly.com are fiddle embeds!
