Configure one rule per model. Watch Contacts, Products, Vendors, or any other model in your database. Each rule is independent and can be enabled or disabled at any time.

Select one or more fields per rule. All selected fields must match for a record to be flagged, giving you precise control over what counts as a duplicate without false positives.

The alert shows the name of the existing record and a clickable link to open it directly. Users can review the existing record and decide whether to proceed or discard their entry.

Uses a limit=1 search that stops at the first match. Works in milliseconds even on tables with 150,000+ records. Zero performance overhead when no rule is configured for a model.

Rules are accessible only to system administrators under Settings > Technical. Regular users see the warnings but cannot modify or disable the rules.

Duplicate checks run on both record creation and editing. If an edit makes a record match an existing one, the alert fires and shows the conflict before the save completes.

Bulk imports and programmatic operations can bypass the check using the duplicate_skip context key. This prevents noise during migrations and batch data loads.
