Flowise Deployment Architecture
How to Set Up Flowise on a VPS
Step 1: Provision your VPS
Choose your VPS provider (we recommend Hetzner for the best value), select an Ubuntu 24.04 LTS image, and configure your SSH keys. Most providers have this ready in under 2 minutes.
Step 2: Install Flowise with Docker or npm
SSH into your server, install Docker and Docker Compose, and pull the Flowise container image. Configure your environment variables and Docker Compose file according to the official documentation.
Step 3: Configure chatflows and API access
Set up Nginx as a reverse proxy with SSL certificates from Let's Encrypt. Point your domain to the server IP, and your Flowise instance will be accessible via HTTPS.
