If it were intended to be a direct alternative for the biggest use case, I think it would be more like Cloudflare Workers and Durable Objects. However, I think it's an alternative for a lot of uses of those two things. For a lot of uses of them, likely most uses, they are overkill.

So where it's overkill, this is where Celld is a good fit. It's a 100% open play, despite mentioning three hosted APIs: S3, Cloudflare Workers, and Durable Objects. The thing is, that Deno tried making similar ones. Deno Deploy is analagous to S3, and Deno KV is analagous to Durable Objects. However, with Celld the only dependencies are being able to run a binary and some S3-compatible storage. Cloudflare provides S3 compatible storage, but this README doesn't mention that, except in an example. Perhaps Ryan is leaving the door open for Deno to be acquired by Cloudflare.

FWIW here's an old Deno blog post comparing Durable Objects to other stuff: https://denoland.medium.com/deno-kv-vs-cloudflare-workers-kv...
