Visualize database query execution trees, identify sequential table scan bottlenecks, and get automated index recommendations.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Run EXPLAIN (ANALYZE, BUFFERS, FORMAT JSON) in your database and paste the output.
Inspect the tree hierarchy to find slow sequential scans and high-cost joins.
Review automated index advisor recommendations and copy optimization SQL.
Run `EXPLAIN (ANALYZE, BUFFERS, FORMAT JSON) SELECT ...` in psql, pgAdmin, or DBeaver, then paste the resulting JSON.
No. All parsing and tree rendering takes place 100% locally in your browser memory.
