OpenSign™

OpenSign™ is a free, open-source electronic signature platform that lets users securely sign documents and manage signing workflows. It provides a complete alternative to paid e-signature services, offering legally binding signatures that comply with international standards including eIDAS, ESIGN, and UETA. Users can upload documents, add signature fields, and send them to multiple signers with tracking and reminder capabilities.

The platform stands out for its commitment to openness and privacy. Unlike proprietary solutions, OpenSign™ offers full source code access, allowing organizations to self-host the solution for maximum data control. It includes all essential e-signature features: multiple signature types (hand-drawn, typed, uploaded), document tracking, audit trails, and multi-language support. The free plan provides unlimited documents and signers without hidden costs.

OpenSign™ works best for small businesses, legal teams, and organizations that need secure document signing without subscription fees. Real-world applications include signing vendor contracts, employee onboarding documents, client agreements, and nonprofit paperwork. Its self-hosting option makes it particularly valuable for industries with strict data privacy requirements like healthcare, legal services, and government agencies.
