EDITOR'S TAKE

Actor-based state machines. ~27k stars. Overkill for most apps but unbeatable for genuinely complex workflows — multi-step forms, async retries with rollback, real-time collaboration. Worth learning even if you do not adopt.

Use this if

You have a genuinely complex workflow with many states, transitions, and side effects.

Skip if

You have toggles and modals — useState is enough.
