DocuSeal | Open Source Document Signing
Free and Open source tool to streamline document filling and signing. Create custom PDF forms to complete and sign with an easy to use online tool. Automatic digital signature.
Categories:
DocuSeal is an open-source alternative to DocuSign that enables users to create, fill, and sign digital documents securely and efficiently online.
🚀 Overview
DocuSeal provides a free, open-source platform for streamlining document filling and signing workflows. Users can upload PDFs, DOCX, images, or ZIP files up to 100MB, add customizable fillable fields, send signature requests via email, and track completions—all while ensuring legally binding e-signatures compliant with ESIGN, UETA, eIDAS, HIPAA, SOC 2, and GDPR.
This project solves the high costs, vendor lock-in, and privacy issues of proprietary tools like DocuSign or PandaDoc by offering a self-hostable, extensible alternative with full API access. It's built for individuals (free forever), small teams, developers integrating signing into apps, and enterprises needing compliance and control.
Bootstrapped by co-founders Kriti, Pete, and Alex, DocuSeal was created to make professional e-signing simple, fast, accessible, and privacy-focused, empowering businesses from startups to large orgs without external investor pressures.
