$5 includes a generous free tier for Workers KV that can hold upto 10MiB of data against a single key. Cloudflare does not charge for bandwidth consumed, I believe. Also, use of Cloudflare's zonal http-cache is free.

I guess, when I compared, I took Lambda@Edge's per second billing into consideration and not per 50ms (which brings down the RAM usage cost from $62.52 to $3.13 and total usage from $68.52 to $9.13).

What really sealed the deal for me was the very low cold-start times with Workers. I'm not aware of recent improvements with Lambda@Edge, but the last time I tried them, it wasn't uncommon to hit 100ms+ start times.

That's interesting, thanks. I haven't really used Cloudflare Workers for much myself so it's interesting to hear folks' comparisons.

One more thing, I am not sure if Lambda@Edge charges based on wall-time or cpu-time. Workers' 50ms is cpu-time only and not wall-time. You could, in theory, spend 30s waiting for a fetch to return as awaiting on the network doesn't count against a Workers' 50ms cpu-time limit.
