Paste a PostgreSQL query and get deterministic + heuristic findings, risk and lint grades, access-path hints, and safe rewrite suggestions. No execution required — pure static analysis in your browser.
This is a PostgreSQL linter, not a performance oracle. It analyses the parse tree of the SQL you paste — it never connects to a database and never runs your query. Schema-aware checks (does this index already exist? is this column nullable?) are reserved for the signed-in version.
Start free with one primary or standalone PostgreSQL instance and all its databases. Monitoring, alerts, query insights, index advice, team access and every non-AI feature included. No replicas. No credit card required. New Free connections get seven days of full collection, then reduced sampling. Free and Pro include 30 days of monitoring history.
