Deploy Langflow Pre-releases

Langflow is a visual framework for building multi-agent and RAG applications

This template is a simple setup that provides a persistent database with the use of PostgreSQL.

Environment variables:

• LANGFLOW_LOG_LEVEL: this is used to set the Langflow's logging level to improve debugging experience and to better control the logs.
• LANGFLOW_PORT: sets Langflow port. Defaults to Railway's exposed port.
• LANGFLOW_SECRET_KEY: Secret Key. Set it to a Secret value as this is used for authentication.
• LANGFLOW_DATABASE_URL: Set this to the DATABASE_URL. This is set to the URL of the Postgres instance that we set up in this template.

Other environment variables can be found in the Langflow repo. All Langflow variables should start with LANGFLOW_.
