Community Extensions

This page serves as a registry of community-created Superset extensions. These extensions are developed and maintained by community members and are not officially supported or vetted by the Apache Superset project. Before installing any community extension, administrators are responsible for evaluating the extension's source code for security vulnerabilities, performance impact, UI/UX quality, and compatibility with their Superset deployment.
