QueryLens
See exactly which query is slowing your app down
Overview
QueryLens is a drop-in Postgres observability agent that surfaces slow queries with the code path that issued them.
The problem
Developers know the database is slow but not which line of application code caused it. Existing tools are priced for enterprises.
The solution
A lightweight agent correlates Postgres statement statistics with application traces and shows the offending code path with a suggested index.
Who it's for
Small engineering teams running self-hosted Postgres.
How it works
The agent samples pg_stat_statements, matches statements to traces via query comments, and ranks problems by total time cost rather than raw duration.
What's next
Managed hosting, automatic index recommendations, and a MySQL adapter.
