DocuSeal is an open source platform for digital document signing and form filling that provides an alternative to commercial services like DocuSign.
The tool addresses the need for secure, self-hosted document signing by letting users create PDF forms with a visual builder, have them filled and signed online, and verify signatures automatically. It supports multiple submitters per document, automated email notifications, and stores files on disk or cloud storage services. The platform includes an API and webhooks for integration into other systems, with a mobile-optimized interface available in multiple languages.
Organizations should choose this tool if they need document signing capabilities they can self-host or deploy to their own infrastructure, want to avoid vendor lock-in with commercial alternatives, or require white-labeling and custom branding. It suits projects ranging from simple document workflows to complex multi-party signing scenarios. The open source core provides essential signing and form-filling features, while pro features add capabilities like SSO, conditional fields, bulk sending, and embedded signing components for React, Vue, and Angular applications.
Almost all open issues are raised by outside users rather than the core team, indicating a substantial base of adopters reporting real-world use. Maintainers typically respond to new issues and pull requests within a day.
