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.

Docker

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

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.

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.
