Self-hostable e-signature platform for creating, sending, and signing PDF forms with automatic digital signatures, a REST API, and embeddable components.

DocuSeal is an e-signature platform built for individuals, small teams, and developers who need legally binding document signing without paying DocuSign or PandaDoc prices. You can upload PDFs, DOCX, XLSX, or image files, build custom form fields, and send signing requests by email in minutes.
