If we can get for the fact that we require javascript to run it, aside from that. Cloudflare workers is literally the best single thing to happen at least to me. With a single domain, I have done so many personal projects for problems I found interesting and I built so many projects for literally free, no Credit card. No worries whatsoever.
I might ditch writing other languages for server based like golang even though I like golang more just because cloudflare workers exists.
