ZeroSign
Zero-cloud, ultra-lightweight DocuSign alternative
Hey Product Hunt! π
I'm thrilled to share ZeroSign with you today! π
Like many developers, freelancers, and small business owners, I found myself in an annoying dilemma:
DocuSign and Adobe Sign charge steep monthly subscription fees ($40β$60/mo) and impose artificial envelope limits just to collect signatures on routine agreements.
When I looked into self-hosted open-source alternatives, I hit another wall: almost all of them are enterprise monoliths requiring 4GB+ RAM, multiple Docker containers, external PostgreSQL or MongoDB databases, and complicated setup scripts just to stamp a name on a PDF.
So I decided to build ZeroSign:
1. Lightweight & Fast: Boots in under 2 seconds, consumes < 60MB RAM, and requires zero external database configuration.
2. True Data Sovereignty: Your confidential contracts, NDAs, and customer data never leave your own server.
3. Cryptographically Verifiable: Every executed contract gets embedded with SHA-256 checksums, sequential audit logs, and an official Certificate of Completion that anyone can independently verify.
4. 100% Permissive MIT License: Free forever for individuals, startups, and commercial projects.
We just published our official v1.0.0 release on GitHub with full test coverage (66/66 passing tests) and a visual PDF field studio!
Iβd love to hear your thoughts, feedback, and feature requests. What features would you like to see next?
Thank you so much for checking out ZeroSign! β€οΈ
