Lowdefy is an open-source framework for building web applications from declarative YAML configuration. Teams use it to create internal tools, admin panels, customer portals and dashboards. The framework includes dozens of UI components, authentication through Auth.js with role-based access control, a plugin ecosystem and connectors for MongoDB, PostgreSQL, MySQL, Google Sheets, REST APIs and Elasticsearch, among others.
Lowdefy is published under the Apache 2.0 licence and is built and maintained by Resonancy, a services company with offices in Cape Town, Johannesburg, Sydney and Vancouver. Applications run anywhere Node.js runs, so you decide in which region the software and the data are located, for example in a European cloud. Resonancy also offers paid managed hosting. The company is based outside the EU; when you self-host, however, data processing stays in your own environment. For a European organisation, sovereignty then depends mainly on the chosen hosting provider and the connected data sources.
