Databricks currently does not provide a free, workspace‑level cost viewer—all usage/cost dashboards are account‑level and require a SQL Warehouse, which does create cost.
So your request is valid and aligns with what many customers want.
Here are few options you can try:
Option 1 — Use AWS Cost Explorer with Workspace Tags (Best free solution)
If your Databricks workspace has a workspace tag (e.g., WorkspaceName, Environment, Owner), then AWS Cost Explorer can break down costs per workspace successfully.
--Free
--No SQL warehouse
--Workspace admins only see their workspace if IAM permissions are scoped
Option 2 — Use the Databricks Billable Usage API directly (No SQL warehouse)
https://docs.databricks.com/api/account/billableusage/download
You can run this on a jobs compute with a tiny cluster → cost is extremely low, and you avoid the SQL Warehouse.
Option 3 — Use System Tables (if enabled)
