You can run trigger in your own infra. That has very little to do with the libraries used for your web app

Trigger and friends exist precisely because Node is not a serious backend runtime so you have to reach for bolt-ons for every little thing. No matter if trigger is open source or managed, it's an anti-pattern. Erlang/Elixir, C#, Go etc all handle this sort of async natively, literally out of the box. Mature frameworks like Rails, Django have pretty easy to use officially libraries as well. This has been a solved problem for literally decades.
