Open Source eSignature Self-Hosted: Own Your Data, Drop the Per-Seat Bill
DocuSign charges $225 per user per month. Adobe Sign charges by the seat. Dropbox Sign locks your data in a US cloud. DocuSeal is open source, self-hostable, and legally binding - deployed on EU servers by Opsily in under five minutes, with one flat monthly fee and no per-seat charges ever.
Why Teams Leave DocuSign, Adobe Sign, and Dropbox Sign
Three products. Three different ways to charge you more every time your team grows.
The Per-Seat Trap
DocuSign Professional runs $165 to $225 per user per month. Add five people to your team and your bill jumps by over $1,000. Dropbox Sign starts at 12 euros per user per month, which sounds reasonable until you add a few salespeople and an admin. Per-seat pricing is a growth tax. Every new hire costs you twice: the salary, and the SaaS bill that follows them.
Your Data Lives Somewhere Else
DocuSign, Adobe Sign, and Dropbox Sign are US-based services. Your signed contracts, client information, and sensitive documents sit on servers you have no control over. For EU businesses, that is not just inconvenient, it is a GDPR liability. The EU regulators have issued fines over 10 million euros for exactly this kind of arrangement. Self-hosting DocuSeal means your data stays where you put it.
Locked In, Locked Out
Proprietary e-signature platforms use formats and APIs that make leaving expensive. Lower-tier DocuSign plans do not include API access at all. If you want to automate signing workflows or embed them in your product, you have to pay for enterprise tiers first. DocuSeal is AGPLv3-licensed. The source code is on GitHub, 11,700 developers have starred it, and you can audit every line.
Built for teams who need reliability
What DocuSeal Actually Gives Your Team
Not a stripped-down open-source clone. A full-featured document signing platform with capabilities most teams never use on DocuSign because they never paid for that tier.
Every Field Type Included
DocuSeal ships with 12 field types: Signature, Date, Initials, Text, Checkbox, Radio, Dropdown, File Upload, Email, Phone, Payment, and Stamp. Build complex multi-signer workflows with conditional logic and formula fields. Bulk-send from a spreadsheet when you need 200 NDAs signed before a product launch. The WYSIWYG form builder requires no training. One user called it: 2 minutes to set up, compared to PandaDoc.
Legally Binding Everywhere
DocuSeal signatures comply with the ESIGN Act (US), UETA (US), and eIDAS (EU). Every signed document includes a full audit log and PDF signature verification. SMS verification adds identity confirmation for high-stakes contracts. DocuSeal also holds SOC 2, ISO 27001, and HIPAA certifications, which matters if you work in healthcare, finance, or any regulated industry.
Built for Developers Too
Eight official SDKs: JavaScript, TypeScript, Python, Ruby, PHP, Java, C#, and Go. A REST API and real-time webhooks for document signing events. Embedded signing forms for React, Vue, Angular, and vanilla JavaScript. Integrations with Zapier, Make.com, and n8n for no-code automation. Whether your team uses it through the UI or builds it into a product, DocuSeal covers both paths.

Why Open Source eSignature Self-Hosted Makes Sense in 2026
The argument used to be that self-hosting was for engineers. That is no longer true. And the reasons to own your own infrastructure have only gotten stronger.
GDPR Is Not Optional
If you are based in the EU, or if any of your customers are, GDPR applies to every document you send for signature. DocuSeal.eu hosts data in Dublin, Ireland. Opsily runs on Hetzner servers in Frankfurt, Germany. Self-hosted means your signing data never touches a US server. That is not a nice-to-have for EU teams, it is the difference between compliance and a fine.
Flat Pricing Scales With You
SaaS e-signature tools punish growth. Self-hosting on Opsily means one flat monthly fee that does not change when you add users. Hire five more people in Q3, send 500 more documents in Q4, the bill stays the same. DocuSeal itself is open source with no per-document or per-user charges at the application level. Your team size is your business, not your billing department's.
Active Project, Real Maintainers
Self-hosted software has a reputation for being abandoned. DocuSeal is not. It has 2,557 commits, 147 releases, 1,000+ forks, and an active community on GitHub Discussions and Discord. The project is under AGPLv3 so commercial forks are required to publish changes. You get the transparency of open source and the reliability of a well-resourced maintainer team behind it.

The Right Choice for Sensitive Contract and Signature Data
Signed contracts contain salary figures, client terms, NDA details, and personal identification. That data belongs on a server you own, in a jurisdiction you trust, not floating in a US cloud SaaS vendor's multi-tenant infrastructure.
GDPR Compliant Hosting
Opsily runs on Hetzner servers in Frankfurt, Germany. DocuSeal.eu operates from Dublin, Ireland. Every document your team signs stays inside the EU. For businesses with EU customers or EU employees, this is the only configuration that is defensible under GDPR enforcement.
eIDAS and ESIGN Legally Binding
DocuSeal signatures satisfy the EU eIDAS regulation, the US ESIGN Act, and the US UETA. Every signed document includes a cryptographic audit log and a verifiable PDF certificate. Your contracts hold up in court in both the EU and the US.
SOC 2, ISO 27001, HIPAA
DocuSeal carries SOC 2, ISO 27001, and HIPAA certifications. This matters for healthcare organizations, financial services teams, and any company that needs to prove due diligence to enterprise clients or auditors. Self-hosted on Opsily means the certification applies to a server under your control.
Full Source Code Transparency
DocuSeal is published under the AGPLv3 license on GitHub. Any developer on your team can read the source code, verify what it does with your documents, and confirm there is no hidden data collection. This is the only e-signature platform where that audit is actually possible.
Your Server, Your Backups
Opsily takes automated 7-day backups of your server. Your DocuSeal data, templates, signed documents, and audit logs are backed up on a schedule you can trust. If a SaaS provider goes down or goes away, you lose access. On Opsily, your data is yours to export, migrate, or restore at any time.
Common Questions About Managed DocuSeal Hosting
Everything you need to know before you deploy your own open source esignature self-hosted platform.
Yes. The DocuSeal open source edition (AGPLv3) is free to self-host with no license cost and no per-user or per-document fees at the application level. You pay for the infrastructure to run it, which is what the Opsily hosting plans cover. The free tier on DocuSeal cloud handles 10 signing requests per month, but self-hosted has no such limit. Opsily's flat monthly fee gives you a fully managed server without a DevOps hire.
