Deploy and Host Dify on Railway

Dify is an open-source platform for building production-grade LLM apps. It blends agentic workflows, RAG pipelines, model management, observability, and a visual builder so teams can go from prototype to production fast, while keeping full control in self-hosted setups. (GitHub, Dify Docs)

About Hosting Dify

Hosting Dify on Railway is straightforward: provision a service from this template, set environment variables, and connect core services. Dify runs well via Docker Compose or Helm; for production you’ll typically wire up PostgreSQL, Redis, an object store (S3/Azure/OSS/GCS), and a vector database. Configure public URLs (console and API), enable HTTPS on a custom domain, and monitor logs as you scale resources. If you choose local file storage, mount a persistent Volume; otherwise point Dify to external object storage. This mirrors Dify’s self-hosting guidance and common K8s/Docker setups. (Dify Docs, Dify, Artifact Hub)

Common Use Cases

• Build agentic assistants and workflow-driven AI apps for support, ops, and internal tools. (GitHub)
• Create RAG pipelines and knowledge bases with vector search and observability. (Dify Docs)
• Extend with plugins and integrate multiple model providers securely via environment variables. (Dify Docs)

Dependencies for Dify Hosting

• Core services: PostgreSQL and Redis; File storage: local or S3-compatible backends (S3, Azure Blob, OSS, etc.). (Dify, Artifact Hub)
• Vector database: Weaviate, Qdrant, Milvus, pgvector and many others (configurable via VECTOR_STORE). (GitHub)
