DocuSeal is an open-source alternative to DocuSign, a self-hostable platform for creating, filling, and signing digital documents. If your business needs to send contracts, agreements, or forms for people to sign electronically, DocuSeal lets you do that without paying for a commercial e-signature service and while keeping your document data on your own servers. The workflow is straightforward: you upload a PDF, use a drag-and-drop form builder to place fields (signature, date, text, checkbox, file upload, etc.) where you need them, then send the document to one or more people for them to fill and sign online, from any device, including mobile. Once signed, the PDF is stamped with a verified electronic signature. The platform also handles automated email notifications via SMTP, signature verification, user management, and can store uploaded files on local disk or cloud storage. An API and webhook system lets you integrate DocuSeal into other software products. The pro tier (paid cloud or self-hosted license) adds features like branded/white-label setup, user roles, conditional form fields, bulk send via spreadsheet import, SMS identity verification, single sign-on, and the ability to embed the signing or form-builder interface directly into other web apps. Deployment is straightforward: a single Docker command starts it in minutes, using a local database by default with optional PostgreSQL or MySQL support. It can also be deployed on platforms like Heroku, Railway, DigitalOcean, and Render. Written in Ruby, licensed under AGPLv3.
