Compute language SDKs

The Compute platform can run any application compiled to WebAssembly, but we provide official support for several popular languages.

Choose the version number link below to view the full SDK reference for the language of your choice, or choose "more about {language}" to read about the core concepts and principles of using that language with the Compute platform.

Other language SDKs for the Compute platform exist but are not supported by Fastly, and if you want to run a language we don't support, you are welcome to write your own SDK. For more information see Unofficial SDKs for the Compute platform.
