This looms nice and I starred but you just want actors and there are other options for that you might want to compare, I like rika actors, or temporal (not actors exactly but durable state and workflows). This is a space where a few very similar technologies after looked from different lenses sell themselves widely differently. So if you know what you want and the names of the things you are searching for you can get a thing that looks 90% like te rest, sorry a bit rambly. But yeah it would be nice to add some comparisons against these technologies as well.
