Documenso vs Native PDF signatures
Both are alternatives to DocuSign. Here's how they stack up — verified facts, no spin.
Also searched as Native PDF signatures 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.
Native PDF signatures
For internal documents, your operating system may already do this.
Worth asking before buying anything: a large share of what companies route through DocuSign is internal — a policy acknowledgement, an expense approval, an NDA between two employees. macOS Preview, Adobe Acrobat Reader and most PDF tools apply a signature with a certificate at no cost, and for internal documents that is frequently sufficient. This is not a product recommendation; it is a scope check. E-signature platforms earn their price on external, contested, high-value agreements — not on getting a colleague to initial a form.
