An open-source alternative to Dropbox Sign

DocuSeal is the one project in our catalog listed as a replacement for Dropbox Sign. It is documents software with 19K GitHub stars. Below is how it measures against the questions people usually ask first.

DocuSeal

Documents

Send PDFs to be filled in and signed online, on your own server.

DocuSeal lets a business send documents for signature from its own server instead of a hosted service. You prepare a PDF once, send it to the people who need to sign, and get back a signed file. Keeping it in-house means contracts and the personal data in them stay under your control.

  • Visual builder places 12 field types, including signatures, on any PDF.
  • Sends one document to several signers by email and signs the final PDF.
  • Includes an API, webhooks and user management in the free edition.

What people use it for

Turn a PDF contract into a signing form

Upload the PDF and use the visual form builder to place fields such as signature, date, file and checkbox where they belong. Save it as a template so the same contract can be sent again without rebuilding it. Signers can complete the form on a phone or a computer.

Collect signatures from several people

Add more than one submitter to a template, such as a customer and a manager, and assign fields to each. DocuSeal sends the signing requests by email through your SMTP server. When everyone has finished, the completed PDF is signed automatically and its signature can be verified later.

Start signing from your own systems

Use the API to create signing requests from another application, such as a CRM or HR system. Webhooks tell that system when a document has been completed. Store the finished files on local disk or in AWS S3, Google Cloud Storage or Azure.
