How to install Flowise on a Cloud VPS

Flowise is a visual drag-and-drop builder for LLM apps and AI agents, connecting models, vector stores and your data without writing code.

Running it on your own server keeps your data and API keys with you, with no SaaS usage limits and predictable hourly billing.

One-click install on cloudlinux.ro

The fastest way: Flowise installs automatically at the first boot of a new server.

1. Create a Cloud VPS from the control panel.
2. In the configuration step, pick Flowise from the app catalog.
3. Start the server. The install runs in the background for a few minutes and its status shows on the server page.
4. Access details and generated passwords are saved on the server in /root/app-credentials.txt. The app will be available on port 3000.

Manual install on any Ubuntu server

If you prefer doing it yourself, below is the exact script our automatic install runs. Execute it as root on a fresh Ubuntu server (24.04 recommended). It stops at the first error, and when it finishes you will find the access details in /root/app-credentials.txt.

export DEBIAN_FRONTEND=noninteractive
curl -fsSL https://get.docker.com | sh
FLOWISE_PASS=$(openssl rand -base64 24 | tr -dc 'A-Za-z0-9' | cut -c1-16)
docker volume create flowise_data
docker run -d --name flowise --restart=always -p 3000:3000 \
  -v flowise_data:/root/.flowise \
  -e FLOWISE_USERNAME=admin -e FLOWISE_PASSWORD="$FLOWISE_PASS" \
  flowiseai/flowise
IP=$(hostname -I | awk '{print $1}')
printf 'Flowise: http://%s:3000\nUtilizator: admin\nParola: %s\n' "$IP" "$FLOWISE_PASS" > /root/app-credentials.txt

You can also save this script as a recipe in your account and reuse it on any new server.
