Deploy and Host Dify (w/ AI model setup) on Railway

Dify is an open-source builder for AI apps, agents and workflows. Put your OpenAI, Anthropic or OpenRouter key in the deploy form: Setup creates your admin, installs the provider and picks default models, so apps work after sign-in.

Implementation Details

Architecture: you and your apps reach Dify through one public router; Setup adds your model keys; the plugin daemon calls OpenAI, Anthropic or OpenRouter; the rest stays on the private network

Knowledge bases need an OpenAI or OpenRouter key. To add a key later, set it on Setup and redeploy. Back up Postgres and the Bucket. SMTP email needs a Railway Pro plan.
