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 and OpenSign are closely matched on ownership (91 vs 84) — this one comes down to pricing and to which trade-offs below you can live with.
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.

Documenso
Strengths
- +No envelope cap — the constraint that drives most DocuSign overage bills
- +Real cryptographic signing with a full audit trail
- +Self-hosted, so contracts never leave your infrastructure
- +Open and specific about how its signing actually works
Trade-offs
- −AGPL-3.0 needs reading before embedding it in a product
- −Fewer integrations than DocuSign's ecosystem
- −Younger, with a shorter legal track record
- −Advanced routing and conditional logic are thinner
OpenSign
Strengths
- +Feature set aimed directly at DocuSign parity
- +Familiar interface — minimal retraining
- +Bulk sending and templates included
- +Self-hostable with no envelope limits
Trade-offs
- −Licensing has shifted historically — check current terms yourself
- −Smaller community than Documenso
- −Less transparent about signing internals
- −Shorter production track record
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Documenso
if a lower exit cost matters more to you than any single feature, and no envelope cap — the constraint that drives most DocuSign overage bills.
Choose OpenSign
if feature set aimed directly at DocuSign parity.
Neither, yet
if both carry a real cost you should weigh first — aGPL-3.0 needs reading before embedding it in a product, and licensing has shifted historically — check current terms yourself. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
Documenso vs OpenSign — common questions
Is Documenso a better fit than OpenSign for e-signature?
It depends on what you are optimising for, and the honest split is this: Documenso scores 91 to OpenSign's 84 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. OpenSign earns its place on a different axis — feature set aimed directly at DocuSign parity. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Documenso keeps its data local or in open formats, so leaving is an export rather than a negotiation. OpenSign is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host Documenso or OpenSign?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are Documenso and OpenSign both alternatives to DocuSign?
Yes — both appear in our DocuSign comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off DocuSign and now choosing between the two replacements, which is a narrower and much easier question.
