MongoDB Atlas Cost Optimization
Cut your MongoDB Atlas bill. OhChimp reads your invoice to flag costly clusters, dedicated clusters without autoscaling, and backup-heavy spend.
How does OhChimp connect to MongoDB Atlas?
With an organization API key pair (public and private key) over HTTP Digest auth to the Atlas Administration API. The key needs only the Org Billing Viewer and Org Read Only roles. OhChimp reads your pending invoice and cluster configuration metadata, and never stores application data, secrets, or workload contents.
Does OhChimp need write access or see my data?
No. The required roles, Org Billing Viewer and Org Read Only, are read-only. OhChimp reads billing line items and cluster configuration only. It never reads your collections or documents, and never stores application data, secrets, or workload contents.
What MongoDB Atlas costs can OhChimp actually reduce?
The big ones are over-provisioned or non-production clusters topping your month-to-date invoice, dedicated clusters (M30 and up) running without compute autoscaling, paused clusters still carrying compute charges, and backup-heavy invoices where snapshot frequency or retention is the lever. OhChimp also breaks spend down by SKU family so you can see whether compute, backups, or data transfer drives the bill.
Who applies the changes, and can they be rolled back?
You do. Each fix is a reviewable plan with a confidence score, a risk level, and rollback steps. Nothing changes until you click apply, and you are always the one who clicks. OhChimp applies the matching code and infrastructure changes together.
How are MongoDB Atlas savings verified, and what does it cost?
Against your real Atlas bill. The cost figures come straight from your billed invoice cents, so a plan is marked VERIFIED only after 7 or more days, a drop of at least 10%, and 3 consecutive positive checks. Otherwise it stays flagged not implemented. Pricing is a flat monthly fee, OhChimp never takes a cut of your savings, and paid plans carry a year-one ROI guarantee: a full refund of subscription fees if it does not pay for itself in the first 12 months.
