The templates above build saga infrastructure from scratch — saga stores, event publishers, compensation tracking. Durable execution frameworks (like DBOS) eliminate much of this boilerplate: the workflow runtime automatically persists state to a database, retries failed steps, and resumes from the last checkpoint after crashes. Instead of building a SagaOrchestrator base class, you write a workflow function with steps — the framework handles persistence, crash recovery, and exactly-once execution semantics. Consider durable execution when you want saga-like reliability without managing the coordination infrastructure yourself.
Works well with: event-sourcing-architect, workflow-automation, dbos-*
