Core Architecture

Everything you need to build complex queries without writing a single line of syntax.

Unlimited nesting depth

Build condition hierarchies as deep as your data requires without any performance degradation.

Triple query output

Export to raw SQL, MongoDB BSON, or GraphQL fragments with a single click.

Schema-driven inputs

Dynamic UI generation based on your data schema — date pickers, enum dropdowns, number ranges.

Drag & drop

Reorder logic blocks visually to re-prioritize query execution.

Undo / redo

Full state history tracking — 50 steps deep — for complex experimentation.

Validation engine

Catches type mismatches, empty groups, and invalid ranges before you run.

Keyboard shortcuts

Ctrl+Z, Ctrl+Enter, Ctrl+Shift+E — full keyboard workflow for power users.
