An open-source platform for digitally signing documents, designed to be self-hosted and transparent.
Documenso is an open-source document signing platform that allows users to digitally sign PDFs and other documents. It solves the problem of relying on proprietary e-signature services by providing a transparent, self-hostable alternative where users can control their own signing infrastructure and verify how signatures are processed.
Organizations and developers who need a secure, transparent document signing solution they can self-host, such as businesses handling sensitive contracts, legal teams, and privacy-conscious enterprises.
Developers choose Documenso because it offers full transparency through open-source code, allows complete control via self-hosting, and provides a trusted alternative to closed-source e-signature platforms without vendor lock-in.
The Open Source DocuSign Alternative.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Documenso allows self-hosting on your own servers, giving complete ownership over data and infrastructure, as emphasized in its philosophy of avoiding proprietary black-box systems.
The entire project is open-source under AGPLv3, enabling users to audit how signatures are processed and stored, which builds trust through transparency.
It uses a familiar tech stack like TypeScript, Prisma, and Tailwind CSS, and offers quickstart options with Docker and DevContainers, making setup easier for developers.
Supports multiple hosting methods including Docker, Railway, and Render, with detailed guides for self-hosting, catering to various infrastructure preferences.
Active community engagement through Discord and GitHub discussions, with a public roadmap, encourages contributions and aligns development with user needs.
The project is still working towards its first production release, so it may lack the stability, feature completeness, and extensive testing of mature alternatives like DocuSign.
Requires manual configuration of environment variables, Postgres databases, and SMTP servers, which can be error-prone and time-consuming for non-technical teams.
Unlike proprietary services, it has fewer pre-built integrations with common business tools, potentially requiring custom development for seamless workflow integration.
The AGPLv3 license mandates sharing modifications if deployed publicly, which could be a legal hurdle for some commercial or modified deployments.
