Documenso

Documenso is an open source alternative to DocuSign that lets you sign documents and manage signing workflows from your own infrastructure or their cloud. You can send signature requests, set signing order, and embed signing links directly into your apps or websites. It supports PDF documents and tracks the entire signing lifecycle with timestamps and audit trails.

The software runs on Linux via Docker, integrates with databases like PostgreSQL, and offers a REST API for automation. A CLI tool is available for advanced users. Documenso is built by Documenso Inc. and provides both a hosted SaaS tier and a self-hosted community edition under the AGPLv3 license. The self-hosted version gives you full control over your document data.

This tool is a good fit for teams that want to avoid vendor lock-in and keep sensitive documents on their own servers. The cloud tier starts free with limited signatures, which makes it easy to test before committing to a paid plan. Notable integrations include Nextcloud and ownCloud for document storage workflows.
