The SaaS eSignature trap
Proprietary eSignature platforms like DocuSign charge per document, per user, and per feature. Scale from 10 signings to 1,000, and your bill multiplies. Compliance features (GDPR, audit trails, multi-factor auth) cost extra. If you want to leave, your signatures stay locked in their system.
How open-source changes the equation
DocuSeal is MIT-licensed. The code is public on GitHub. You can audit the signing logic yourself. You own the data. You control where it's stored.
With Opsily, you get the open-source freedom plus enterprise operations: automated backups, GDPR compliance, 99.9% uptime SLA, and security patches shipped daily. No vendor lock-in. If Opsily's pricing ever gets too high, you can migrate to another host or run DocuSeal on your own infrastructure.
Real-world math
A 50-person company signing 2,000 documents per month on DocuSign pays roughly EUR3,000/month (at their Standard plan rates, plus envelope charges). On Opsily with DocuSeal: EUR70/month for unlimited documents, unlimited signers, unlimited envelopes. That's EUR36,000/year in savings. More importantly, it's predictable. No overages. No surprises.
