Documenso

Open-source DocuSign alternative for e-signatures and contract flows.

Documenso is an open-source digital document-signing platform, positioned as an alternative to DocuSign, built with Next.js, React, TypeScript, and Prisma. It handles signature fields, signer ordering, templates, audit trails, and embeddable signing flows with cryptographic signing of the resulting PDFs. It is notable for being self-hostable and exposing an API plus webhooks for embedding signing into sales and onboarding pipelines.
