What LibreSign is
LibreSign is a free, open-source electronic-signature web application from the LibreCode cooperative. It requires Nextcloud and can be self-hosted on an organization’s Nextcloud instance. Signing workflows can include internal and external participants, configurable order, and progress tracking through completion. Documents may use personal digital certificates or certificates generated by the system. LibreSign supports SES, AES, and QES workflows; QES requires a qualified PFX digital certificate. The maker describes end-to-end encryption and multi-factor authentication as security features. An audit trail records signing activity, and a REST API connects signing processes with other systems. Users can access the service through a browser on smartphones or tablets. There is no monthly limit on documents or signatures and no software license fee. Managed hosting and professional support are optional paid services. LibreCode lists businesses, cooperatives, public-sector organizations, legal teams, and IT professionals as intended users. eIDAS compliance depends on the certificate, identity verification, hosting, and operating process used.
