The Open Source Alternative to DocuSign You Actually Control
DocuSign charges per seat, per envelope, and locks your templates in a proprietary format you cannot export. DocuSeal is a fully open source e-signature platform with 11.7K GitHub stars, legal compliance across ESIGN, UETA, and eIDAS, and zero per-seat fees. Opsily deploys it on your own GDPR-compliant EU server in under 3 minutes.
Why Teams Choose an Open Source Alternative to DocuSign
It is not about features. It is about the bill that keeps growing as your team does.
Per-Seat Pricing Punishes Growth
DocuSign starts around $10 per user per month, and that is before envelope overages kick in. Add five people to a deal workflow and the bill climbs before anyone signs anything. DocuSeal Pro is $20 per user per month with unlimited signature requests and no envelope caps. The math changes quickly, especially for teams sending more than a handful of documents each month.
Your Templates Are Theirs, Not Yours
DocuSign templates are stored in a proprietary format. If you cancel, they do not export cleanly to any open-source alternative. DocuSeal reads standard PDF and DOCX files. You build templates on files you already own, and they stay yours regardless of who hosts the software. Vendor lock-in is not a feature.
Data Goes to US Servers by Default
Cloud-only competitors, including DocuSign and Adobe Sign, process signature data on US infrastructure. For European companies operating under GDPR, that means relying on standard contractual clauses and hoping the processor does its part. DocuSeal on Opsily runs in Germany. Your documents stay in the EU, and you own the server they live on.
Built for teams who need reliability
What DocuSeal Actually Gives Your Team
This is not a stripped-down open source tool. It is a full document signing platform built for real workflows.
Twelve Field Types, One Builder
DocuSeal includes a WYSIWYG PDF form builder with 12 field types: signature, initials, date, text, checkbox, file upload, and more. You upload a PDF or DOCX, drag fields onto it, assign signers, and send. Sequential or parallel signer order is supported. Most teams have their first template live in under 10 minutes.
Legal Compliance Out of the Box
DocuSeal signatures are legally binding under the US ESIGN Act, UETA, and the EU eIDAS regulation. Every signing session creates a tamper-evident audit log with timestamps, IP addresses, and signer identity records. HIPAA compliance is included. If anyone ever asks whether your signatures hold up in court, the answer is yes and you have the audit trail to prove it.
API and Automation From Day One
A full REST API, JavaScript, TypeScript, and Python SDKs, plus native webhooks make DocuSeal pluggable into any stack. Connect it to n8n, Zapier, or Make.com for CRM syncing or post-signing automation. Embed the signing interface directly in your own app if you need a white-labeled experience. The API does not require an enterprise plan: it is included and priced at $0.20 per document signed through the API.

Why Self-Hosting Makes Sense in 2025
Managed by Opsily means self-hosted without the maintenance headache.
GDPR Compliance You Can Certify
When DocuSeal runs on your own Opsily server in Germany, you are the data controller and the data processor. There is no sub-processor sending your signing data offshore. GDPR Article 28 compliance becomes straightforward because the data never leaves infrastructure you control. EU healthcare, finance, and government teams can sign off on this without a legal grey area.
No Maintenance, No DevOps Needed
Self-hosting sounds like it means managing servers at 2am. Opsily handles that part: security updates, SSL certificates, 7-day encrypted backups, and autoscaling are included on every plan. You get the data sovereignty of self-hosting without needing a DevOps engineer on staff. Your team uses DocuSeal. Opsily keeps it running.
One Flat Monthly Fee, Unlimited Users
Every Opsily plan is priced by server, not by seat. Add every person in your company to DocuSeal and the monthly fee does not change. Dropbox Sign charges around $10 per user per month. PandaDoc starts at around $19 per user per month. With Opsily, you pay one flat fee and stop counting heads.

The Right Choice for Document Signing Data
Signing data is sensitive. Contracts, NDAs, employment agreements, and health consent forms should live on a server you control, not in a vendor's shared cloud. DocuSeal on Opsily gives you both the compliance and the control.
GDPR Data Residency
Your DocuSeal instance runs on Hetzner infrastructure in Frankfurt, Germany. Document data never leaves the EU. You are the data controller under GDPR Article 28, with no US sub-processors in the signing chain.
eIDAS Legal Validity
DocuSeal signatures comply with the EU eIDAS regulation, making them legally valid across all EU member states. Advanced and qualified signature options are available for workflows requiring a higher level of assurance.
ESIGN and UETA Compliant
Every signature collected through DocuSeal meets the US ESIGN Act and UETA standards for legal enforceability. Audit logs capture signer identity, IP address, timestamp, and document hash so you have proof at every step.
HIPAA-Ready Hosting
Healthcare providers using DocuSeal for patient consent forms and clinical document workflows can deploy on Opsily with HIPAA compliance in mind. Data stays on your server, encrypted at rest and in transit, with 7-day backup retention.
Encrypted Backups Included
Opsily takes encrypted daily backups on every plan with 7-day retention. If something goes wrong, your signing data and templates are recoverable. No separate backup service required, no extra fee.
