A free, self-hostable e-signature platform with multi-signer PDF workflows, OTP verification, audit trails, REST API, and Zapier integration — ESIGN Act and eIDAS compliant.
DocuVerify is a free, self-hostable e-signature platform providing the complete feature set of commercial signing tools — multi-signer PDF workflows, hand-drawn/typed/uploaded signatures, OTP verification, document expiration, audit trails, REST API access, Zapier integration, and CRM connections — deployable with a single Docker command. With ESIGN Act / eIDAS compliance, it delivers legally binding document signing at zero per-user cost.
Small and mid-market businesses paying $25–50 per user per month for DocuSign or Adobe Sign face a straightforward cost calculation: for teams of 10–50 people, that’s $3,000–30,000 per year for infrastructure that is, at its core, a PDF with a cryptographically verified signature and a timestamp. For professional services firms, real estate agencies, staffing companies, and HR teams processing hundreds of documents monthly, the per-signature economics are particularly punishing. API access — needed to embed signing into existing CRM and workflow tools — often requires enterprise tiers that cost significantly more.
DocuVerify provides full e-signature functionality with no per-user or per-document fees. The Node.js backend uses Parse Server as the BaaS layer for document management, signer records, and audit trail storage. MongoDB stores document metadata and signing history. Multi-signer workflows support sequential and parallel signing orders. OTP verification via email or SMS provides additional identity assurance. The REST API enables programmatic document creation, signer invitation, and status tracking for integration with CRM, HRMS, and custom workflow tools. Zapier and n8n webhook integrations connect DocuVerify to 5,000+ applications without code. Self-hosted deployment via Docker Compose means the entire platform runs on a $20/month virtual machine.
