fastly - Compute@Edge

Fastly lets you run wasm using their [Compute@Edge]( product. - Their JavaScript runtime is based on [spidermonkey](/spidermonkey/). - They seems to only support HTTP requests from their wasm applications, no socket or DB support.

Viceroy > Viceroy provides local testing for developers working with Compute@Edge. It allows you to run services written against the Compute@Edge APIs on your local development machine, and allows you to configure testing backends for your service to communicate with. Uses [wasmtime](/wasmtime/).
