DocuSeal vs OpenSign

Self-host pick — both replace DocuSign (Electronic signature / document signing).

Both DocuSeal and OpenSign self-host as a replacement for DocuSign (Electronic signature / document signing). Pick DocuSeal if you want the lighter footprint — 10min docker-compose (Ruby on Rails + Postgres), $10 vps; same trusted-timestamp / signing-cert situation as documenso. 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.
