Keep your Azure bill in check
Finimbus scans your Azure resources, old and new, and shows where your money leaks away. Keep the infrastructure your AI tools generate aligned with your budget.
Finimbus reads your environment. It can’t change, create or delete anything.
Scans run and your data is stored in an EU region, under the GDPR.
Infrastructure now writes itself, and someone still pays for it
AI tools and templates create Azure resources in seconds. Finimbus checks what they cost, so your invoice holds fewer surprises. Every resource you stop paying for is also one that stops running.
From subscription to suggestion
Link a subscription, run a scan, and work through what Finimbus finds, biggest savings first. It never changes anything itself. You decide what happens to each suggestion.
Link a subscription
Create a read-only service principal in your own Entra tenant and choose the subscriptions to check. Finimbus proves the access by using it, and can’t change, create or delete anything.
Run a scan
Start a scan when you want one. Every rule runs against what you linked, and each match becomes a suggestion that names the rule and explains why the resource matched.
Start with the biggest wins
Suggestions are ranked by the saving they promise and the effort they take, so the most bang for your buck comes first. Each one comes with an Azure CLI command.
Resolve, snooze or ignore
Act on it, and the next scan confirms it’s gone. Snooze it for a day or for years, or ignore it for good. You can reopen anything you set aside.
Don’t trust a black box
Every suggestion names the rule behind it and explains why your resource matched. No hidden scores, no guesswork.
Finimbus ships with 385 rules for App Service, Functions, storage, Log Analytics, Key Vault, containers, databases and more. Each rule looks for one specific way Azure spend quietly drifts.
