I just spent the last two weeks digging into workflow state engines and temporal was one of the candidates. It is a VC backed fork of Cadence. The got 0.3B funding and whatever positive I read about them on the net I take with a big spoon of salt. Just my 2 cents.
I would love to read your analysis somewhere. It's a current interest of mine, both hobby and professional -- and limited to Elixir, Golang and Rust -- and I'm still slowly scoping the landscape.
Recommendations for good engines? Or just thoughts and analyses?
