Docuseal

DocuSeal is an open-source, self-hosted web app and server that provides a platform for digital document signing and processing. It allows users to create PDF forms that can be filled and signed online via a mobile-optimized web interface. The software is deployed as a server application, often via Docker, and supports various database backends including SQLite, PostgreSQL, and MySQL. It is designed for use cases requiring secure electronic signatures across different devices, ensuring that documents are processed efficiently without relying on third-party proprietary cloud services.

Administrators can manage the entire document lifecycle from template creation to final signature verification. The system handles the distribution of documents to multiple signers and manages the collection of required data through a variety of input fields. Because it is self-hosted, it allows organizations to maintain full control over their sensitive legal documents and user data, avoiding the subscription costs and data privacy concerns associated with centralized e-signature providers.
