# 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.**
