Cloudflare's Workers have a good dev experience. It takes a second to build and locally preview a function. It live-reloads when you make a change. Later, it takes a second to build and deploy. On the flip side, Workers can't run arbitrary Docker containers. Your code has to be JS/TS or WebAssembly.
I'm not affiliated with Cloudflare, just a satisfied customer.
My experience has been the opposite.
Wrangler doesn't give you any meaningful errors (since it converts JS errors to Rust) and it crashes way too often.
Recently I worked on a Workers project and I had an undefined missing variable. The only error Wrangler would output is "error".
IMO Workers are only viable for really small and simple projects.
Containers are coming to the Cloudflare edge: https://blog.cloudflare.com/containers-on-the-edge/ (inevitable really)
Nit: Workers should really be compared to Lambda@Edge instead.
Am I right in saying that they serve a somewhat narrower use case than lambdas though? My understanding is that they are mostly used for things like modifying requests/responses rather than for building a whole backend.
