OpenSign
Open-source alternative to DocuSign, Adobe Acrobat Sign, PandaDoc
OpenSign is an open-source alternative to DocuSign, Adobe Acrobat Sign, and PandaDoc for signing documents online. It lets you send, sign, and track agreements through a browser, with audit trails that record every step. Businesses can self-host it to keep sensitive documents on their own servers.
Key features
- Send and sign documents in a web browser
- Audit trails for every signature workflow
- Self-hosted option for sensitive documents
Before you switch
Switching productivity tools is mostly about habits, not features. Pick one workflow — notes, tasks, or documents — and run it in the new tool for two weeks before migrating everything. Check that import tools exist for your current app; most open-source alternatives offer them. Self-hosted options give you full ownership of your data, which is worth the small setup cost if privacy matters to you.
Like every project on OpenShelf, OpenSign is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
