Documenso vs OpenSign
Self-host pick — both replace DocuSign (Electronic signature / document signing).
Both Documenso and OpenSign self-host as a replacement for DocuSign (Electronic signature / document signing). Pick Documenso if you want the lighter footprint — 15min docker-compose (Next.js app + Postgres), $10 vps for the next. Pick OpenSign if you need teams that want SAML/OAuth team auth, role-based templates, and a Notion-style workspace shape around contracts — 20min docker-compose (Next.js + ParseServer + MongoDB) and $10-15 vps for the multi-container stack.
