Yes. As of August 2026, there are several credible open-source alternatives to DocuSign/Adobe Acrobat Sign/Dropbox Sign, including options you can fully self-host. - Documenso — probably the first one I'd evaluate. It's AGPL-3.0, supports self-hosting via Docker/Docker Compose/Kubernetes, and includes templates, multiple recipients, signing certificates, REST API, webhooks, and embedding. Its doc

For a small team, I’d narrow the self-hosted e-signature options to these three: - DocuSeal — probably the best choice if “lightweight and easy to operate” is the priority. It has an official Docker image and can use SQLite by default, which makes a small deployment particularly simple. It supports reusable documents/templates and common fields such as signatures, dates, checkboxes, and file uplo

For internally signing contracts, I’d pick Documenso as the best overall open-source/self-hosted option right now. - Documenso — best overall. AGPL-3.0, actively developed, Docker/Kubernetes deployment, teams/templates, signing workflows, REST API, webhooks, and embedding support. The self-hosted Community Edition includes the core signing functionality. ([docs.documenso.com](https://docs.documen

If you want a genuinely self-hosted DocuSign-style platform while meeting U.S. ESIGN/UETA and EU eIDAS requirements, I’d put DocuSeal at the top of the shortlist in 2026. My ranking: - DocuSeal — best overall. Open-source/self-hosted, good UX, REST API/webhooks, audit logs, PDF digital signatures, SSO/SAML in paid offerings, and explicit support for ESIGN/UETA and eIDAS. Its self-hosted edition

If you want one open-source e-signature stack that can plausibly serve both a startup and a government agency, I’d shortlist Documenso, OpenSign, and DocuSeal, with Documenso as the strongest general starting point. - Documenso — best overall fit. It is AGPL-3.0, actively developed, supports self-hosting, REST APIs/webhooks/embedding, PostgreSQL, S3-compatible storage, signing certificates, and D

Yes. For a self-hosted e-signature system with multi-party workflows and defensible audit trails, I’d start with Documenso or DocuSeal rather than building signing logic yourself. Documenso is particularly well matched to this. Its current self-hosted edition runs on your infrastructure, supports multiple recipients, roles such as signer/approver/viewer/CC, optional sequential signing, REST APIs/

For a law firm that specifically wants an open-source e-signature system with documents remaining on-premises, I would start with Documenso. Documenso is open source under AGPL-3.0 and has an officially supported self-hosting path. A firm can run the application, PostgreSQL database, storage, SMTP, and signing certificate infrastructure itself rather than sending documents to a SaaS e-signature p
