Common Pain Points

Sound Familiar?

Every data team using BigQuery faces the same challenges

$

Rising Bills

Unused tables in BigQuery keep generating storage costs. Your monthly bill keeps growing.

?

What's Safe to Delete?

Team members come and go. No one knows which tables are still in use and which can be safely removed.

T

Manual Checks Take Forever

Manually auditing BigQuery usage is tedious and error-prone. Engineers' time should be spent on more valuable work.

Core Features

No Unused Table Goes Unnoticed

BQ Optimizer provides a complete solution

S

Unused Table Detection

Analyze job history to identify tables that haven't been queried, with configurable day thresholds.

N

Proactive Notifications

Send analysis reports via Slack Webhook. No need to remember to check - keep your team informed about unused tables.

V

Your Key, Your Control

Upload a Service Account with read-only BigQuery access. Delete the connection at any time and we erase the key along with every row we collected.

How It Works

Start Saving in 3 Steps

Simple setup, immediate results

1

Configure Service Account

Upload a Service Account key with read-only BigQuery permissions. We use it for nothing except reading INFORMATION_SCHEMA.

2

Connect Notification Channel

Set up a Slack Webhook URL and choose the channel where you want to receive reports.

3

Receive Regular Reports

The system will regularly analyze and send reports listing all unused tables for your team to review.

Exactly What We Access

R
Read-only. We never write to or modify anything in your project.
I
We query INFORMATION_SCHEMA only — job history and table metadata. Never the contents of your tables.
Q
Job history includes each query's SQL text and the email of the account that ran it, so we can show you who last touched a table.
D
We keep collected history for as long as the connection exists — that history is what makes "unused for 90 days" answerable. Delete the connection and the key and every row we collected go with it.
