Choose an n8n deployment by its service composition. Start with the SQLite-backed standard configuration, use PostgreSQL for a separate database, and review the worker variant's compatibility warnings before choosing queue-based execution.
Run n8n on Polyer to connect services and build automated workflows. The standard catalog template runs n8n with a separate task-runner service and local SQLite storage; use the related PostgreSQL variant if you need a separate database. Review the actual service composition and configuration before deploying.
Run n8n with a dedicated PostgreSQL database on Polyer to build and host automated workflows. Alongside n8n and its external task runner, this variant adds a private PostgreSQL 16 service that stores workflows, credentials and execution history instead of SQLite. Review both persistent volumes before deploying.
