How to install Cal.com on a Cloud VPS

Cal.com is the open-source scheduling platform (a Calendly alternative) for bookings, team round-robins and calendar integrations under your own brand.

The self-hosted version removes per-user subscriptions: you pay only for the server, no matter how many teammates use the app.

One-click install on cloudlinux.ro

The fastest way: Cal.com 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 Cal.com 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
DB_PASS=$(openssl rand -base64 24 | tr -dc 'A-Za-z0-9' | cut -c1-20)
NEXTAUTH_SECRET=$(openssl rand -base64 32)
ENCRYPTION_KEY=$(openssl rand -base64 32)
IP=$(hostname -I | awk '{print $1}')
docker network create calcom
docker volume create calcom_db
docker run -d --name calcom-db --restart=always --network calcom \
  -e POSTGRES_DB=calcom -e POSTGRES_USER=calcom -e POSTGRES_PASSWORD="$DB_PASS" \
  -v calcom_db:/var/lib/postgresql/data postgres:16
sleep 10
docker run -d --name calcom --restart=always --network calcom -p 3000:3000 \
  -e DATABASE_URL="postgresql://calcom:${DB_PASS}@calcom-db:5432/calcom" \
  -e DATABASE_DIRECT_URL="postgresql://calcom:${DB_PASS}@calcom-db:5432/calcom" \
  -e NEXTAUTH_SECRET="$NEXTAUTH_SECRET" -e CALENDSO_ENCRYPTION_KEY="$ENCRYPTION_KEY" \
  -e NEXT_PUBLIC_WEBAPP_URL="http://${IP}:3000" \
  calcom/cal.com:latest
printf 'Cal.com: http://%s:3000\nCreeaza contul la prima accesare (prima pornire dureaza 1-2 minute).\n' "$IP" > /root/app-credentials.txt

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