docuseal

DocuSeal is an open-source document signing platform that lets you create fillable PDF forms and have them signed online. It's a self-hosted alternative to DocuSign with features like multiple signers, automated emails, and cloud storage integration.

What docuseal is

Ruby on Rails application providing WYSIWYG PDF form building, e-signature capability, SMTP automation, and pluggable storage (disk/S3/GCS/Azure). Offers REST API, webhooks, and supports PostgreSQL or MySQL alongside default SQLite; deployable via Docker.

Quickstart

Get the docuseal source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/docusealco/docuseal.git2cd docuseal3# follow the project's README for install & configuration

Best use cases

Small-to-Medium Businesses Needing Cost Control

Self-hosted deployment eliminates per-signature SaaS fees. Suitable for organizations with moderate signing volume and stricter data residency requirements.

Document-Heavy Workflows (Real Estate, Healthcare, Finance)

Multi-submitter support, bulk CSV/XLSX import (Pro), conditional fields, and webhook integrations enable automated document collection and processing pipelines.

Embedded Signing in Custom Applications

React, Vue, Angular, and plain JavaScript SDKs allow seamless integration into existing web/mobile products without redirecting users off-platform.

Implementation considerations

Database choice (SQLite for dev/small, PostgreSQL/MySQL for production) affects scalability and backup strategy; plan accordingly.
AGPL-3.0 copyleft: any modifications or linked code must be licensed compatibly or your derivative must be open-source. Review with legal if customization is planned.
Pro features (white-label, SSO/SAML, conditional logic, bulk import) are paid tier; clarify feature roadmap against budget constraints.
Email delivery depends on SMTP configuration; ensure relay, SPF/DKIM/DMARC setup to avoid signing emails landing in spam.
PDF signature verification and automated eSignature rely on embedded cryptographic keys; audit key rotation and expiry policies before production.

When to avoid it — and what to weigh

Require Commercial Closed-Source Deployment — AGPL-3.0 license requires sharing derivative works. Proprietary forks or modifications trigger source-code disclosure obligations unless separately licensed.
Need Zero DevOps / Managed SaaS Only — Self-hosting demands infrastructure management, database setup, and SSL/TLS configuration. Requires engineering or DevOps involvement; cloud option exists but is separate.
Rely on Mature Enterprise Compliance Certifications — No SOC 2, ISO 27001, HIPAA, or eIDAS compliance status documented. Assessment required if regulatory/audit requirements are strict.
Require Turnkey Mobile App (iOS/Android) — Platform is web-only. Mobile support is via responsive web UI, not native apps. Integration into native mobile workflows requires custom development.

License & commercial use

AGPL-3.0 with Additional Terms (Section 7(b)). Strong copyleft: network use triggers disclosure. Any modified or linked derivative works must be licensed under compatible terms or open-sourced. Review LICENSE and LICENSE_ADDITIONAL_TERMS files before commercial deployment.

Using unmodified DocuSeal as-is for commercial operations is permitted under AGPL. However, modifying the code, forking, or linking it into proprietary applications requires either opening your modifications under AGPL or obtaining a separate commercial license from DocuSeal LLC. Do not assume you can white-label without license clarification.

Security considerations

No audit reports, penetration test results, or formal security certifications provided. Key considerations: (1) AGPL source is public; security-by-obscurity does not apply. (2) PDF signature verification and eSignature implementation must be cryptographically sound; no claims of formal validation. (3) SMTP and storage credentials must be managed securely in self-hosted environments. (4) No mention of input sanitization, CSRF protections, or OAuth 2.0 token expiry policies. (5) Self-hosted instances bear responsibility for network isolation, TLS enforcement, and access control. Conduct threat modeling and code review before handling sensitive documents.

Alternatives to consider

DocuSign

Fully managed SaaS with strong compliance certifications, mature API, and enterprise support. Higher cost per signature; proprietary; no self-hosting option.

Docspring / Fillout

SaaS-only, lighter-weight, focuses on form filling over signing. Lower setup overhead; weaker signing/workflow features compared to DocuSeal.

Nextcloud + OnlyOffice

Open-source file collab platform with document editing; no native e-signature. Requires separate signing workflow integration; lower cost but more setup.

docuseal FAQ

Can I use DocuSeal commercially without open-sourcing my code?

Using unmodified DocuSeal is allowed. Modifying or integrating it into proprietary software requires opening your changes under AGPL or obtaining a separate commercial license. Contact DocuSeal LLC for licensing options.

What database should I use for production?

SQLite is included but not recommended for production. Use PostgreSQL or MySQL with proper backup, monitoring, and failover strategies. Docker Compose example includes PostgreSQL.

Is there a managed cloud version?

Yes, a cloud offering exists (docuseal.com/sign_up), but it is separate from the open-source self-hosted version. Terms and pricing for cloud are not detailed in the README.

What e-signature standards does DocuSeal support?

Automatic PDF eSignature and verification are mentioned, but specific standards (e.g., PAdES, XAdES, eIDAS compliance) are not documented in the README. Review the full documentation or contact the team.
