Paste a query and get plain-English performance findings, a health score, and actionable fixes in seconds — no database connection required.
SELECT * FROM users WHERE email LIKE '%@gmail.com' ORDER BY created_at;
Pattern “%@gmail.com” can’t use a B-tree index — forces a full scan.
Project only the columns you need to cut network/IO cost.
Sorting every row is expensive — add LIMIT or a covering index.
gin_trgm_ops, or use full-text search.Example output — your results will match your query.
Drop in any Postgres or MySQL query. Nothing connects to your database — it analyzes the query text.
25+ rules flag performance anti-patterns, each with severity and a health score from 0–100.
Every finding includes an actionable recommendation — and an AI explanation of why it matters.
SELECT *, leading-wildcard LIKE, deep OFFSET, cartesian joins, NULL-unsafe NOT IN, functions in WHERE, and more.
Dialect-aware parsing — same UI, both engines, including dialect-specific syntax.
Plain-English “why it matters” for each fix — grounded in the deterministic finding, never invented.
Paste EXPLAIN (FORMAT JSON) and get plan-level insights and index recommendations.
Export any analysis as a PDF and revisit your past runs anytime.
Queries are encrypted at rest, PII is masked, and we never store database credentials.
It’s free during beta. Paste a query and see what comes back.
