Built for data teams that move fast

Everything you need to find and eliminate Fivetran waste in minutes, not days.

Read-only access

We never modify your data. Connect with view-only credentials and disconnect anytime.

5 minute setup

Connect your warehouse and see results instantly. No agents, no schema changes.

MAR-aware analysis

Calculate waste using Fivetran Monthly Active Rows pricing, not generic metrics.

Disable directly

Pause or disable connectors straight from the Optimisely dashboard with one click.

60 day lookback

Identify tables unused over 30, 60, or 90 day windows. Find the real dead weight.

Data stays secure

Your data never leaves your warehouse. We query metadata only, never table contents.

You know there is waste. You just cannot find it fast enough.

You are paying Fivetran to sync hundreds of tables into your warehouse, but half of them have not been touched in months. Every unused table costs you Monthly Active Rows. Digging through INFORMATION_SCHEMA to find them is a day's work you never get round to.

Three steps to a smaller data bill

From connection to savings in under 5 minutes.

1

Connect your warehouse

Read-only access to BigQuery or Snowflake. Takes 60 seconds. No schema changes, no agents to install.

2

We find the dead weight

Optimisely queries your audit logs to find Fivetran tables that nobody has touched in 30, 60, or 90 days and calculates their MAR cost.

3

Disable with one click

See a ranked list of tables by wasted spend. Disable the connectors directly from the dashboard or copy the config to your Fivetran admin.

Common questions

How does Optimisely cut Fivetran costs?+

We connect to your warehouse, identify Fivetran-synced tables that have not been queried recently, calculate the Monthly Active Rows cost of each unused table, and show you exactly which connectors to disable.

Is it really free?+

The initial analysis is free and takes about 5 minutes. You only pay if you want ongoing monitoring and automated recommendations.

What warehouses do you support?+

Google BigQuery and Snowflake today. Databricks and Redshift are on the roadmap.

Do you have access to my data?+

No. Optimisely only needs read access to INFORMATION_SCHEMA and audit logs. We never query the contents of your tables.

How much can I save?+

Most teams find 30 to 50 percent of their synced tables going unused. On a 2,000 GBP per month Fivetran bill, that is typically 600 to 1,000 GBP of recoverable spend.
