Dagster wins for asset-based thinking and strong local development. For most UK SMEs starting fresh, Prefect offers the best balance of simplicity and power."

-        "@type": "Answer",
-        "text": "Apache Airflow defines DAGs in Python files and requires a scheduler, workers, and metadata database. Prefect uses a cleaner Python decorator syntax with automatic retry logic and an optional hosted cloud UI. Prefect is faster to get started with; Airflow has a larger ecosystem of pre-built operators."

-        "@type": "Answer",
-        "text": "Yes. Airflow with LocalExecutor runs on 2 vCPUs and 4GB RAM for light workloads. Prefect is lighter if you use Prefect Cloud for the UI. Dagster typically needs 4GB+ RAM. All three work on standard UK VPS providers like Hetzner, DigitalOcean, or OVH."
