# Deploy and Host Flowise – Self-Hosted AI Agent Builder on Railway

Flowise is the most popular open-source drag-and-drop UI for building LLM-powered applications, AI agents, and chatbots. Deploy your own Flowise instance on Railway in under 2 minutes — no DevOps expertise needed. Perfect for developers, startups, and enterprises who want full control over their AI workflows without vendor lock-in.

## About Hosting Flowise on Railway

Flowise lets you build production-ready AI applications using a visual node-based editor. By hosting Flowise on Railway, you get automatic HTTPS, persistent storage, zero-downtime deploys, and instant scaling — all without touching a server. Railway handles the infrastructure so you can focus on building powerful AI workflows with GPT-4, Claude, Gemini, Llama, and 100+ other LLM integrations.

This template deploys Flowise with:
- Persistent local SQLite database (no additional DB cost)
- Configurable username/password authentication
- Health-check monitoring via /api/v1/ping
- Auto-restart on failure with 10 retries
- File upload support up to 50MB
- Pre-configured storage paths for flows, API keys, and logs

## Common Use Cases

- **RAG Pipelines**: Build Retrieval-Augmented Generation apps over your own documents, PDFs, Notion pages, or databases
- **AI Chatbots**: Deploy customer support bots, FAQ assistants, or internal knowledge base chatbots
- **Autonomous AI Agents**: Create multi-step agents that browse the web, write code, or call external APIs
- **LLM Orchestration**: Chain multiple LLMs, tools, and memory systems in a visual no-code interface
- **No-Code AI Apps**: Let non-technical team members build and modify AI workflows without writing code
- **API Backend**: Expose your AI flows as REST API endpoints for integration with any application
