LakeSentry is now a native **Databricks App**, installable straight from the [Databricks Marketplace](https://marketplace.databricks.com/details/7700a2dd-b649-428c-9758-eeeadf9b90cc/Tier-One-Analytics_LakeSentry-Databricks-Cost-Observability). Databricks [opened the Marketplace to third-party apps](https://www.databricks.com/blog/announcing-apps-databricks-marketplace) at Data + AI Summit 2026, and LakeSentry was one of the launch apps.

LakeSentry gives Databricks teams cost observability: it attributes spend across workspaces, flags cost anomalies before the invoice does, and surfaces what to optimize. As a Databricks App, all of it now runs inside your own account.

## Built on Databricks, Running in Your Account

LakeSentry runs entirely on the Databricks Apps runtime, in your own workspace. Its backend is PostgreSQL, so it keeps its cost ledger in a [Databricks Lakebase](https://www.databricks.com/product/lakebase) database you own and govern under Unity Catalog. Usage data, query text, and credentials never leave your account. The only thing that does is a periodic license check.

That makes it a clean fit for teams that need their cost data to stay in their environment, often to clear a security review. The attribution, anomaly detection, and optimization are identical to our [hosted SaaS](/); only the boundary moves.

## Get Started

Install LakeSentry from the [Databricks Marketplace](https://marketplace.databricks.com/details/7700a2dd-b649-428c-9758-eeeadf9b90cc/Tier-One-Analytics_LakeSentry-Databricks-Cost-Observability), or see the [LakeSentry Databricks App page](/databricks-app/) for the architecture and a step-by-step install. Cost observability — now native to Databricks.
