Deno is a new open source rust-based typescript v8 javascript engine.
Deno recently launched their Deno Deploy product, which is a full fledged edge compute platform completely built for the Deno/javascript/typescript landscape.
Deno offers a nice local worker environment which full support for Worker Environments.
The Deno library size is not that big at the time of writing, but with the underlying tech, this should only be a matter of time.
Fastly, traditionally a CDN, was one of the first CDNs that openly and actively promoted it’s edge worker technology.
Fastly has been open and quick when it comes to adding features and functionality to their Serverless product. The platform is runs on WASM logic (with JIT compilation). All in all, one could expect very fast responses when it comes to running your application on Fastly.
Fastly has a unique online fiddler tool to experiment and try different Edge features and functionality without even having to register, live log tailing and individual end-user request trailing. A notable customer of Fastly’s Edge Compute platform is LoveHolidays.
