OpenSign versus Docusign
Compare	OpenSign	Docusign
Verdict	Depends	Depends
Best for	Cost-sensitive small businesses	Regulated industries (finance, government, legal)
Who it's not for	Legal, healthcare, finance teams needing audited compliance	Freelancers sending a few documents a year
Privacy	Multiple CVEs published in 2026 including auth bypass and unauthenticated tenant data exposure; vendor security page was returning a 404.¹⁰	Enterprise-grade trust program, but multiple 2024 CVEs, a 2017 email-database breach, and heavy brand-impersonation phishing.
Support quality	Trustpilot sentiment 'Average'; no SLA evidence	Only complaint threads found, no rating evidence
Public sentiment	Self-hosters on Reddit praise the free, quick setup, and Capterra reviewers are positive, but Trustpilot sentiment is only average and review snippets lack ratings.	Users praise how easy signing is, but price is by far the most common complaint.¹⁴
Biggest gotcha	Self-hosting means you own patching; 2026 CVEs show updates lag exploitability¹³	Envelope limits and add-on fees mean real cost exceeds sticker price
