DocuSeal

Open source platform for secure digital document signing and processing

Alternative to: docusign

DocuSeal lets you create PDF forms with a drag-and-drop builder and collect legally binding signatures from one or more parties, all on infrastructure you control. It supports multi-party signing, an embeddable JavaScript widget, a REST API, and automated email invitations with audit trails.

DocuSeal Docker Compose example

Self-host DocuSeal on your own server, homelab, or VPS starting from this Docker Compose example. It runs DocuSeal in Docker containers using the official docuseal/docuseal:latest, postgres:18 images, with persistent volumes and automatic restarts preconfigured. Review the environment variables and adjust them to your setup, save the file as compose.yml (or docker-compose.yml), and start the stack with docker compose up -d.

services:
  app:
    image: docuseal/docuseal:latest
    depends_on:
      postgres:

    volumes:

    restart: unless-stopped
    environment:
      # External host DocuSeal is served on, e.g. docuseal.example.com. Used to build absolute links. Leave empty to derive it from the request.
      HOST: ""
      # Host for which to force HTTPS redirects. Set to your external domain when running behind an HTTPS reverse proxy.
      FORCE_SSL: ""
      # PostgreSQL connection string. Points at the bundled postgres service below.
