Documenso

Documenso started in 2022 with a straightforward premise: document signing should be open infrastructure, not a per-envelope toll booth. The result is a Next.js and Prisma application backed by Postgres that covers the full signing lifecycle. A sender uploads a PDF, places signature, initials, date, and custom text field widgets at precise positions, assigns signers with a defined sequence or in parallel, and dispatches email invitations. Each signer authenticates via a secure email link and completes the document in a browser without creating an account.

Every completed signing produces a tamper-evident audit log recording the signer's email, IP address, and timestamp for each action. Reusable templates eliminate the re-upload cycle for recurring agreements like NDAs, offer letters, or service contracts. Team workspaces group documents by organization or client, and role-based access controls who can send, view, or manage templates within each workspace. A public REST API and webhook support let developers wire Documenso into onboarding flows, CRM pipelines, or custom portals programmatically.

Self-hosting via Docker Compose is the primary path for privacy-sensitive deployments — legal, HR, and healthcare teams that cannot route executed contracts through a third-party SaaS platform. The AGPL-3.0 license requires sharing modifications for software distributed externally, which matters for agencies building commercial wrappers. The managed cloud plan prices per seat with no per-document fees, making cost predictable at volume.

The honest gaps relative to DocuSign are enterprise CRM integrations and advanced compliance certifications: Salesforce and SAP connectors don't exist yet, and eIDAS qualified signatures are not yet supported.
