Illuminate your queries
Lantern is a visual query builder for composing database filters without writing SQL by hand. Build nested AND/OR logic, preview SQL/MongoDB/GraphQL output, validate rules, and run against mock data.
What Lantern does
- Conditions — each rule is a field, operator, and value (or a null check).
- Groups — nest conditions with AND/OR, like parentheses in SQL.
- Preview — generated query strings update live in the sidebar.
- Execution — filter sample users or orders in-memory (no real database connected).
