Azure Cost Console

This dashboard reads real spend from Azure Cost Management through a Function App backend (no keys stored client-side beyond a scoped function key) and renders it as charts, KPIs, and exportable breakdowns — no manual pulls from the Portal.

Scope: the primary data source is a management group scoping the core workload subscriptions, queried live and always current. A background job additionally pre-warms cost data for every other subscription in the tenant (refreshed every 4 hours) and merges it in automatically wherever it is available, extending coverage close to tenant-wide without slowing down the primary view. A small number of subscriptions (e.g. platform/identity scaffolding subscriptions) are rejected outright by Cost Management's API regardless of scope, and simply won't appear -- that's an Azure-side limitation, not missing configuration.

Group by resource group, service, resource, or tag (pick a discovered tag key). Subscriptions narrows any view to specific subscriptions, or lets you connect an additional independently-deployed Function App for a subscription outside the above scope. Click any bar to focus that month, expand a row for a live "what's driving this cost" resource breakdown, compare a month against its trailing average, or export the current breakdown/comparison as CSV.

Figures refresh from Cost Management on a short cache (default 30 minutes) to stay within Azure's shared, tenant-wide rate limits - switching tabs rapidly won't force a live re-fetch every time.
