Get started

Pulling from your own system

First, choose and run the utility (options below). The utility:

  • connects to your database to pull your schema
  • extract 10 sample rows per table
  • capture queries (if pg_stat_statements is enabled)

Then, head over to Edit Setup and paste your Postgres connection string.

The analyzer utility powering IndeX-Ray is open source. You can browse the code to see what it does or grab a copy of the zip to run locally. Full instructions below.

Clone it
or
Sync with your database interface

Option 1: Locally, using our Docker image (recommended)

Pre-requisites:

  1. Docker desktop

Run docker run --pull always -t -p 2345:2345 ghcr.io/query-doctor/analyzer

Option 2: Locally, running with Docker

Pre-requisites:

  1. Docker desktop

Then:

  1. either:
  2. docker build -t analyzer .
  3. docker run -p 2345:2345 analyzer

Option 3: Locally, self-built with Node

Pre-requisites:

  1. Node (20+ recommended)
  2. Deno
  3. Postgres 17+

Then:

  1. either:
  2. deno install
  3. deno task start

Option 4: Remotely

Select "QD Hosted" (remote)

Note: this only works for remote databases.

Enabling pg_stat_statements (Highly recommended)

To capture query statistics, enable the pg_stat_statements extension. This is optional but recommended for analyzing live queries.

Run this SQL command:

CREATE EXTENSION IF NOT EXISTS pg_stat_statements;

Note: Depending on your setup, you may need to add pg_stat_statements to shared_preload_libraries in your PostgreSQL configuration and restart the server. If you're using an ORM or migration system, you may need to add this as a migration in your codebase.
