OpenSign

OpenSign is an open-source electronic signature (e-sign) platform for creating signature workflows, sending documents to recipients, and collecting legally relevant signing evidence. It provides a web UI for preparing documents, defining signers and fields, and tracking signature status, with a focus on organization/team workflows.

Key Features

• Create and send signature requests (“envelopes”) to one or more recipients
• Drag-and-drop placement of signing fields (e.g., signature, initials, text/date fields)
• Templates for reusing common document workflows and field layouts
• Email-based signing flow with document status tracking
• Audit trail / activity history for signature events
• Team/organization features (users, roles, shared templates/documents)
• PDF/document upload and in-browser viewing during signing

Use Cases

• Internal HR and onboarding paperwork (offer letters, policies, acknowledgements)
• Sales/procurement approvals (quotes, MSAs, vendor agreements)
• Operations and compliance sign-offs (SOP acknowledgements, change approvals)

OpenSign is a solid choice for teams that want to run their own e-sign workflow and retain control of documents and signing data. It covers common signing needs such as multi-recipient flows, templates, and document tracking while remaining approachable to deploy and operate.
