PlatformsOn your machine or in the cloud
InstallationHosted signup, npx or Docker
ModelsOpenAI, Anthropic, Google and many hosted or open-model providers through AI nodes and LangChain integrations
DataSelf-hosting defaults to SQLite in the persistent .n8n directory; PostgreSQL is supported, credentials are encrypted in the database, and binary files use filesystem or object storage
Limitations compared to ZapierIt is more technical to build and debug, and self-hosting moves reliability and upgrades onto you while Zapier offers a larger turnkey app ecosystem.
