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

BigQuery Integration

Native support for Google BigQuery, built directly into your workflow.
Seamless GCP authentication included.

  • Schema-aware autocomplete for tables and columns
  • Multi-project and multi-dataset support
  • Table previews and row count estimates
  • Secure OAuth — your credentials stay yours

Query History

Every query is saved and instantly searchable.
Pick up where you left off, browse your full history, or re-run any past query in one click.

  • Full timestamped query timeline
  • Side-by-side before/after diff view
  • Re-run any past query in one click
  • Saved projects for team collaboration

Deterministic optimizations.
Every time.

No AI guesswork, no hidden costs, no surprises.
