Open Source Document Signing: Free Tier Without the SaaS Tax
DocuSeal gives you legally binding eSignatures with zero per-envelope fees. Self-host free or get managed hosting from Opsily. No credit card needed to start.
Free Tiers for Document Signing
When you search for open-source document signing free tiers, you're really asking: what can I use without paying per signature?
There are three types:
Free SaaS (cloud). DocuSeal and Documenso both offer free sandbox accounts. No credit card. Upload up to 30 documents, sign unlimited times. Great for testing, but limited for production use.
Free self-hosted. Run the same code yourself on your own servers. Pay zero software costs. You pay for hosting (€20+/month from a VPS provider). Full control, full data privacy, eIDAS-compliant in the EU.
Managed hosting. Best of both worlds. Opsily runs DocuSeal on your behalf. Fixed €30/month. No ops work. EU data residency. Legally binding signatures out of the box.
Companies tired of DocuSign's €0.50-€2 per signature fees are moving here. A legal team signing 1,000 contracts per year saves €500-€2,000 just by switching.
