For teams valuing full control over the execution engine’s code, how does DBOS’s open-source Postgres-backed approach compare to Catalyst’s Dapr-based extensibility?

DBOS provides a fully open-source codebase that directly interacts with Postgres, allowing deep customization of the execution layer. Catalyst, built on Dapr, leverages Dapr’s pluggable state stores and pub/sub, offering extensibility without proprietary lock-in. However, DBOS’s tight coupling to Postgres may require more effort to swap the backing store, while Catalyst’s abstraction can make some Dapr-level tuning less accessible.
