Deterministic workflows still have plenty of use cases. AI agents can help build them, but can’t replace them when predictable and auditable execution matters, because agents are inherently nondeterministic.

That said, Relay.app announced its shutdown a few weeks ago, and now Flowise is winding down too. I wonder whether coding agents are really the cause, or whether these products simply struggled to find a sustainable market.

Disclosure: I’m building Aqua Blue (aquablue.app) around a related idea: AI builds the workflow, but fixed rules run it.
