Query plan explorer
SQL Explain Plan Visualizer
Supports simple indented text plans and row/cost hints.
How it works
- Paste an EXPLAIN plan into the text area.
- Review the rendered tree with cost, row count, and filter hints.
- Use it as a quick local read-through before deeper query tuning.
FAQ
What does this visualizer do?
It turns an EXPLAIN plan into a readable tree so the main scan, join, and filter steps are easier to review.
Does it connect to a database?
No. It works entirely in the browser and only parses the text you paste in.
What plan formats work best?
Indented text plans from PostgreSQL-style EXPLAIN output are the best fit for this lightweight viewer.
