OpenSign

What it does

OpenSign is an open-source PDF signing platform. A sender uploads a document, identifies signers, places signature and other fields, then emails a request or shares a signing link. The service tracks progress and provides the finished file with a completion certificate. Hosted and self-hosted use have different operating and commercial requirements.

Who it is for

A small team handling agreements, forms or approvals can prepare a one-off signing request and see who has viewed or signed. Repeated documents can use templates with defined roles and fields. The team should decide how to authenticate recipients and retain the completed record.

A technically staffed organization can deploy the self-hosted version instead of relying on the hosted service. The official Docker path still requires planning for infrastructure, document storage, email delivery, upgrades and backups.

The work it supports

Core capabilities

The request guide starts with uploading one file and adding any additional pages in the next step. Add a document title and select existing signers or enter new ones. Place the required signature and input widgets before sending so each recipient has an unambiguous task.

For several signers, Send in Order routes the request to the next person after the prior signer completes. The parallel option sends all signing links at once. Choose the sequence deliberately when a document requires a particular approval order.

The sender can set an expiration window. Automatic reminders are paid-only in the request guide and capped at 15. If using that option, check the schedule before sending to real recipients and plan how to restart an expired request.

Signature, initials, text, date and checkbox widgets can collect recipient input. A signer can draw, upload or type a signature in a signature widget. Use a sample document to check field placement on every page and confirm the completed PDF retains the expected content.

After preparation, the sender can email the request or copy its signing link. The guide describes a completed document and certificate available to signers. The option to receive the certificate as a separate PDF instead of merging it into the signed document is marked paid-only.

Templates can hold recurring signer roles and fields, then be reused to prepare another signature request. Check the assigned role and fields on each new document before sending, particularly if the underlying form changes.

The In-Progress report shows document and signer status, activity logs, link sharing, manual reminder resends and access-revocation controls. Review it during a sample request to learn what a stalled or mistaken send looks like before handling sensitive documents.

Understand the offer

Pricing and getting started

OpenSign describes a free self-hosted version with unlimited signatures, and its hosted Terms describe a free tier with unlimited signatures per month plus paid Professional plans. These offers have different hosting responsibilities; compare the current feature entitlements before choosing.

Premium Credits apply to API and bulk sends, public-template signing, kiosk mode and embedded signing. The FAQ says a standard single-document request and ordinary template use do not consume those credits. Check the current credit and plan rules for the exact workflow you will run.

The request guide marks enforced email OTP, automatic reminders and a separate completion-certificate PDF as paid-only. The Terms say a Professional trial can bill automatically for the next cycle unless canceled before its end; confirm the trial length and account terms at sign-up.

The official self-hosting guide documents Docker deployment and ongoing operations. The user-management guide lists Self-Hosted, Teams and Enterprise for administrator management, but its plan names and seat limits should be checked against the current offer.

Look a little closer

Before you choose

Test a fictional document from preparation through signing and final download. Confirm signer order, field placement, expiration behavior and activity logs. If the paid features are needed, test automatic reminders and the separate-certificate PDF against the selected plan.

Before using a real agreement, confirm recipient identity controls, access to signing links, document retention and the legal requirements that apply to that document and jurisdiction. The official guide describes the workflow and a completion certificate; those facts alone do not establish legal sufficiency for every use.
