Frequently Asked Questions
What SQL databases are supported?
PostgreSQL, MySQL, SQLite, and SQL Server execution plans are all supported. Paste your EXPLAIN or EXPLAIN ANALYZE output and get instant visual breakdowns.
How does the visual explanation work?
We parse your execution plan, identify sequential scans, missing indexes, nested loop inefficiencies, and high-cost nodes, then render an interactive diagram with color-coded bottlenecks and fix suggestions.
Is my query data stored or shared?
No. Queries and execution plans are processed in-memory and never persisted to disk or shared with third parties. Your schema stays private.
