WaboSign

Self-hosted document filling and signing

WaboSign is a self-hosted, open-source platform for secure digital document signing and processing. Create PDF forms, fill them in online from any device, and collect signatures with an easy-to-use, mobile-optimized web tool.

WaboSign is a fork of DocuSeal under AGPLv3, with the upstream's "Pro" feature paywall removed so that every shipped capability is available out of the box on a self-hosted deployment.

Features

• PDF form fields builder (WYSIWYG)
• 12 field types (Signature, Date, File, Checkbox, Phone, Verification, etc.)
• Multiple submitters per document
• Automated emails via SMTP
• File storage on disk or AWS S3, Google Storage, Azure Blob
• Automatic PDF eSignature
• PDF signature verification
• User management and roles
• Mobile-optimized signing flow
• 14 UI languages
• API + Webhooks for integrations
• SMS invitations via BulkVS, Twilio, VoIP.ms, or SignalWire
• Bulk send via CSV / XLSX import
• Google Workspace SSO (setup guide)
• Conditional fields and formulas
• Custom branding (logo, colors, reply-to)
• Easy Docker deployment

Docker

docker run --name wabosign -p 3000:3000 -v .:/data ghcr.io/wabolabs/wabosign:1.3.0

:latest always tracks the most recent release; pin a MAJOR.MINOR.PATCH tag for reproducible deployments.

By default the container uses SQLite for data. Point at PostgreSQL or MySQL by setting DATABASE_URL.

Docker Compose

sudo HOST=sign.example.com docker compose up

Make sure your DNS points at the server so Caddy can issue an SSL cert automatically.

Authentication

WaboSign ships with email + password (Devise) and TOTP two-factor auth out of the box. Google Workspace SSO can be enabled by setting three environment variables — see GOOGLE_SSO.md for the full operator guide.

Releases

• Current release: 1.3.0 — see CHANGELOG.md.
• Container image: ghcr.io/wabolabs/wabosign:1.3.0 (or :latest).
• Versioning: MAJOR.MINOR.PATCH per semver.org.
• Tagging triggers a build: pushing a MAJOR.MINOR.PATCH git tag runs .github/workflows/docker.yml, which builds linux/amd64 + linux/arm64 and pushes to GHCR.

Acknowledgements

This software builds on the substantial work of the DocuSeal team. Their open-source release made this fork possible. WaboSign retains the embedding SDK contract (<docuseal-form>, @docuseal/react, @docuseal/vue, @docuseal/angular) so existing DocuSeal embedding code continues to work.
