DocuSeal is an open-source document filling and eSignature platform designed as an alternative to services like DocuSign. It lets you build fillable forms, send signing requests, and produce signed PDFs with verification, optimized for desktop and mobile use.

Key Features

• WYSIWYG PDF form builder with multiple field types (e.g., signature, date, file upload, checkboxes)
• Multi-party submissions with automated email delivery via SMTP
• Automatic PDF eSignature generation and signature verification
• File storage on local disk or S3-compatible/object storage providers
• User management plus API and webhooks for integrations
• Embeddable signing and form-building components for web and app integration
• Optional enterprise capabilities such as SSO/SAML, roles, reminders, and bulk send/import

Use Cases

• Sending contracts, agreements, and HR documents for eSignature
• Embedding document signing inside a SaaS product via API/webhooks
• Building and distributing fillable document templates for repeated workflows

Limitations and Considerations

• Some advanced capabilities (e.g., SSO/SAML, roles, reminders, bulk send) are offered as paid “Pro” features.

DocuSeal fits teams that need a modern eSignature workflow with strong developer integration options. It is suitable for both standalone document signing portals and embedded signing experiences inside other applications.
