Getting started

snowtuner connects to your Snowflake account, learns how your warehouses run, and produces concrete, reversible cost recommendations. On the hosted plan there's nothing to install — sign in and connect.

Connect Snowflake

1. Sign in at app.toulousedata.com and choose Hosted.
2. Enter your Snowflake account identifier and warehouse.
3. We generate a dedicated key pair and show you a one-time bootstrap SQL block — run it once in Snowsight as ACCOUNTADMIN.
4. Click Launch. snowtuner provisions your instance, syncs your history, and starts producing recommendations.

The bootstrap grants are read-mostly: access to ACCOUNT_USAGE and the ability to monitor your warehouses. You stay in control.

Recommendations

Each recommendation includes the exact SQL to run, a rollback statement, a plain-English rationale, and a confidence score. Review them in the app and Accept or Reject — accepted changes can be applied for you.

Autonomous mode

Once you trust the recommendations on a warehouse, enable autonomous mode for it. snowtuner applies new changes above your confidence threshold, with a cooldown between changes and a circuit breaker that pauses autonomy after repeated rollbacks. Every autonomous change records a rollback, so you can revert in one click.

Security

snowtuner uses a dedicated Snowflake service user with RSA key-pair auth and least-privilege grants. We never see your data — only operational metadata needed to produce recommendations. Hosted instances are isolated per customer.

BYOC (Bring Your Own Cloud)

Regulated or privacy-conscious team? snowtuner can run entirely inside your own AWS account, so your query metadata never leaves your environment — managed through the same control plane. Get in touch to set it up.
