Deploy and Host Langflow (w/ admin login) on Railway

Langflow is a visual builder for AI agents and LLM workflows. Recent Langflow releases won't start without an admin password, so this template asks for your login on deploy, keeps your files on a volume and the database private.

About Hosting Langflow (w/ admin login)

You get Langflow 1.13.0, private Postgres and a volume for uploads and knowledge bases, with the encryption key generated per deploy. Type the admin password (and optionally an OpenAI or Anthropic key), then open your Langflow URL and log in. Public sign-up is off; the admin adds users.

Common Use Cases

Implementation Details

Architecture: you and your apps reach Langflow over HTTPS; Postgres stays on the private network; Langflow calls your model providers

Needs about 1.5 GB of memory, so a Hobby plan or higher. Back up the Langflow volume (uploads, knowledge bases) and keep LANGFLOW_SECRET_KEY: it encrypts your saved API keys.
