Features

Optimize every query before it runs

Real-time analysis surfaces unused partitions, costly scans, and schema mismatches as you type - optimizing your SQL before it ever reaches BigQuery.

Real-time Analysis

Get instant feedback on your queries as you type.
Syntax errors and performance issues are highlighted the moment they appear.

  • Highlights syntax errors and warns when queries are missing partition filters for your BigQuery tables
  • Automatically removes unused joins, CTEs, columns, and subqueries
  • Automatically rewrites index-unfriendly functions like LOWER and REGEXP to faster equivalents
  • Catches and fixes dozens of other performance, cost, and style issues across your entire query

Smart Suggestions

A deterministic rule engine built around how BigQuery executes SQL.
No AI guesswork, just consistent, explainable fixes.

  • JOIN order and predicate push-down hints
  • Subquery-to-CTE rewrites for readability
  • Partition pruning and clustering suggestions
  • SELECT * elimination with column awareness
  • Dozens more deterministic rules covering performance, cost, and style — each applied in dependency-resolved execution order for maximum effect

Seamless GCP authentication included.
