Self-hosting DocuSeal on a Hetzner Ubuntu server offers full control over your document signing infrastructure. This approach eliminates per-signature fees and keeps sensitive data private, with a basic CX23 server costing just €2.99 per month. The setup requires an SSH key and basic server management experience.

The process begins by launching a cost-optimized Ubuntu 24.04 server through Hetzner's console. After establishing an SSH connection, you update the system, configure the UFW firewall for essential ports, and install Docker. A reverse proxy like Caddy handles automatic HTTPS via Let's Encrypt, routing traffic to your DocuSeal container.

Deploying DocuSeal itself involves a Docker Compose file specifying the official image and a persistent data volume. For production, the guide recommends switching from SQLite to PostgreSQL and configuring SMTP for email alerts. This self-hosted stack dramatically undercuts managed services like DocuSign, which charge €45+ monthly for limited document quotas.
