I’d recommend talking to the Svix folks, might be a partnership opportunity wrt pushing webhooks around.

That's exactly why we built Svix[1]. Building webhooks services, even with amazing tools like FastAPI, Celery and Redis is still a big pain. So we just built a product to solve it.
Hatchet looks cool nonetheless. Queues are a pain for many other use-cases too.

Well, I hope we get custom allocation soon in Rust. Its really strange not having the same in an advertised system programming language.
Can help in incidents like the below:
