Esup-Signature: sovereignty score and 8 European alternatives

Esup-Signature is a web application for visa and signature workflows, aimed at higher-education and research institutions. Documents can be given a visa or signed with electronic certificates (CAdES, XAdES, PAdES) or by placing an image in a PDF. The software builds on the European Commission's DSS signature framework, integrates with Shibboleth and LDAP, and also includes a module for filling in PDF forms online. It is server software that the institution installs itself, with PostgreSQL among its prerequisites.

Esup-Signature comes from the ESUP-Portail consortium, a French community of higher-education institutions that develops free software; the code is on GitHub under the Apache-2.0 licence. The project is active, with several releases in October 2026. Because the application runs on your own servers, documents and signature data remain under the institution's control and no vendor cloud is required. The project's wiki presents on-premise installation as the intended model.
