Are you talking about R2? If so, requires a credit card, doesn't support atomic deploys or rollbacks, etc.
I'm a CloudFlare user who's used Workers, and trying to sign up for it fails silently here. Bad start for me, doesn't say much, but makes it hard to review further.
That being said, yes, there are competitors. I don't think any offers quite the UX I've built for small teams of experienced developers, but I could be wrong or misguided in my efforts.
