Can I understand it as a performant celery with a UI?

Not the same thing, because celery and the like are sdk-level abstractions that need you to plug in your own queue (usually Redis, Kafka) and all other components. The Temporal server deployment includes the full control plane, queue, persistent database, UI and everything else. So you only need to manage your worker boxes.

		A Rust equivalent to Celery would be something like Apalis [0]. Where every job is just an async function, similar to a Celery task. [0]: https://github.com/apalis-dev/apalis

With better ergonomics around handling failures.
