Government Site Builder

Government Site Builder (GSB) is a web content management solution for creating, reviewing, approving, and publishing material on internet, intranet, and extranet sites. Its current release, GSB 11, is based on TYPO3 and intended for modern, accessible websites. Federal authorities required or choosing to participate in Dienstekonsolidierung are its primary users; states and municipalities can also reuse it. GSB 11 meets Germany’s BITV 2.0 accessibility requirements. Its modular editorial system has extensions for consent management, content modules and templates, website logins, metadata cleaning during uploads, and site configuration import and export. Search extensions include Solr and an adaptation for ITZBund hosting requirements. The product page describes regular updates and security checks by the federal government’s BSI, along with configurations intended to improve security and data protection. Authorities in Dienstekonsolidierung are generally hosted at ITZBund, though self-hosting is possible. Self-hosting or an external provider makes the authority responsible for updates, upgrades, and patches. The Open Source distribution is free under GPL 3.0; hosting, support, training, and custom development may cost extra.
