DocuSeal Open-Source Document Signing

DocuSeal is an open-source, self-hosted document signing and form builder platform that enables organizations to create, send, and manage digital documents for electronic signatures. Created by Igor Alexandrov and launched in 2023, DocuSeal has over 8,500 stars as of 2026 and provides a free, open-source alternative to commercial e-signature platforms like DocuSign, Adobe Sign, and HelloSign. Built with Ruby on Rails and React, DocuSeal is designed to be easy to self-host while providing enterprise-grade document signing capabilities. Key features include: drag-and-drop form builder (creating fillable PDF and document templates by dragging fields like signatures, text, dates, checkboxes, and radio buttons onto document areas), PDF field detection (automatically detecting form fields in existing PDF documents using PDF field mapping), electronic signatures (supporting typed, drawn, and uploaded signature images with audit trails tracking IP addresses, timestamps, and browser fingerprints), multi-recipient workflows (sending documents to multiple signers in sequential or parallel order with configurable signing order), template management (creating reusable document templates with conditional fields, required fields, and default values), submission tracking (monitoring document signing status with email notifications for each stage of the signing process), conditional logic (showing or hiding fields based on other field values), API access (a REST API for programmatic document creation, sending, and status checking), webhook notifications (receiving real-time updates when documents are signed or declined), audit trails (tamper-evident audit logs for legal compliance), S3 and local storage (storing signed documents in Amazon S3 or local filesystem), user management (multi-user accounts with role-based permissions), and Docker deployment (one-command self-hosted deployment via Docker Compose).
