It depends on what you are trying to do and what part of "production-ready" are you asking about (orchestration engine, architecture, stability of Python client, APIs) - are you asking for OSS Prefect 2.0 or for Cloud 2.0? The basic building blocks (flows, tasks, deployments) are stable and can be used for production workloads, but some API routes used under the hood may change. Does this answer your question?
