Explain plan viewer for SQL tuning and review
Execution plans show how a database expects to read, join, filter, and sort data. A visualizer helps developers and DB teams quickly spot table scans, joins, index access, row estimates, and high-cost operations before deeper tuning work begins.
Paste DBMS_XPLAN output, text EXPLAIN output, or copied execution plan snippets when you need a quick first-pass review. The tool is designed for practical triage: finding full scans, join operations, operation counts, object names, cost values, and plan rows that deserve deeper inspection in your database console.
Review plan shape
Turn compact plan output into a readable operation tree with object names and estimates.
Spot common risks
Flag full scans, nested loops, missing index operations, and unusually high detected costs.
Keep data local
The parser runs in the browser and does not need database access or backend credentials.

What does an explain plan visualizer do?
An explain plan visualizer turns SQL execution plan text into a readable operation list and highlights common signals such as joins, full scans, row estimates, and cost values.
Can this parse DBMS_XPLAN output?
Yes. The tool is designed for DBMS_XPLAN-style pipe table output and also handles common text EXPLAIN lines with arrows.
Does this tool connect to a database?
No. It only parses pasted plan text in the browser and does not connect to any database.
