Salesforce Schema Explorer is a free Chrome add-on designed to help developers, admins, and architects visualize object schemas and relationships within Salesforce. This tool allows users to quickly understand data models without the hassle of navigating through the Object Manager or switching between multiple tabs. With just one click, users can access the Schema Explorer from any Salesforce Lightning page, providing a streamlined and efficient way to view incoming and outgoing relationships at a glance.

The extension features an interactive node graph that displays Lookup and Master-Detail relationships using color-coded, directional lines. Users can click on any node to access a complete field list, including type information and attributes. Additional functionalities include smart search with real-time autocomplete, persistent preferences for including or excluding objects, and graph controls to adjust the layout. The tool prioritizes user privacy, processing data locally without analytics or external servers.
