What is it?

DocuSeal is an open source document filling and signing platform. It lets you build fillable PDF forms with a visual field editor, send them to one or more submitters, and collect completed, signed documents through a mobile-friendly web interface.

The project covers a range of field types, including signatures, dates, files and checkboxes, along with automated email delivery over SMTP, signature verification for PDFs, and user management. Files can be stored on local disk or in AWS S3, Google Cloud Storage or Azure. By default it runs on SQLite, and PostgreSQL or MySQL can be configured through DATABASE_URL.

DocuSeal ships with an API and webhooks for integrations, and it can be deployed with Docker, Docker Compose or several one-click hosting platforms. Some capabilities such as SSO/SAML, bulk send, SMS verification and embedded signing components are listed as paid Pro features.
