Documenso vs OpenSign
Both are alternatives to DocuSign. Here's how they stack up — verified facts, no spin.
Also searched as OpenSign vs Documenso — same comparison, one verdict.
Documenso
TOP PICKOpen-source signing with real cryptographic signatures and no envelope cap.
Documenso is the credible open answer: digitally signed PDFs using proper certificates, a complete audit trail, templates, and an API — self-hosted, with no per-envelope charge of any kind. AGPL-3.0, around 14k stars, and unusually transparent about how its signing works, which matters in a category where 'legally binding' is often asserted rather than explained. For a company sending straightforward agreements at volume, it removes both the seat cost and the envelope cap in one move.
OpenSign
A self-hosted signing platform aimed squarely at DocuSign's feature list.
OpenSign covers templates, bulk sending, multiple signers, reminders and an audit trail, with a self-hosted deployment and an interface deliberately familiar to anyone coming from DocuSign. Its aim is feature parity rather than reinvention, which makes it the shortest retraining path for a team that already has a signing process it likes. It is smaller and less established than Documenso, and the project's licensing has moved over time, so check the current terms against your intended use before you commit.
