Deploy and Host Flowise on Railway

Flowise is an open-source, low-code platform for building LLM-powered applications visually. Using a drag-and-drop interface, you can create AI workflows, chatbots, and agents with integrations for OpenAI, Anthropic, Ollama, and more — no deep programming required.

About Hosting Flowise

Hosting Flowise requires a persistent server with access to a database for storing flows, credentials, and chat history. This Railway template deploys Flowise alongside a managed PostgreSQL instance, with all database connection variables automatically wired between services using Railway's private networking. The application runs on port 3000 with a public domain provisioned automatically. A secret key for encrypting stored credentials is generated at deploy time. Railway handles infrastructure provisioning, service restarts on failure, and health monitoring via the /api/v1/ping endpoint.

Common Use Cases

Build custom AI chatbots backed by your own documents (RAG)
Create LLM agents that can call external APIs and tools
Design and test multi-step AI workflows visually
Embed shareable chat interfaces into websites and applications

Dependencies for Flowise Hosting

Flowise (flowiseai/flowise:latest) — LLM application builder and API server
Postgres (Railway-managed) — stores flows, credentials, API keys, and chat history
