mission-finops tools
Free, interactive AWS tools.
Assessments, a decision game, and cost calculators that run locally in your browser. No account, no upload, no charge. Distinct from paid Mission FinOps services: nothing here is a substitute for an AWS Cost Investigation.
Governance & landing-zone tools.
AWS Governance Fit Assessment
A five-round estate builder. Answer questions about your AWS estate and get the lightest defensible landing zone, account-delivery path, and reference architecture, computed locally: nothing you enter leaves your browser.
Launch the assessment →The Landing Zone Game
Make real AWS architecture choices, meet a narrator with opinions about them, and leave with an actual defensible recommendation. An educational, story-driven way to explore the same trade-offs as the Governance Fit Assessment.
Play the game →Cost-decision calculators.
AWS Commitment Stacking Calculator
Model all four compute commitment instruments against one workload at once: zonal and regional Reserved Instances, the EC2 Instance Savings Plan, and the Compute Savings Plan. Break-even utilization and stranding exposure, what the commitment still costs if usage drops and the capacity goes unused, sit on one screen, so the ceiling and the floor of each commitment are visible together.
Open the calculator →Bedrock Total Cost Model
Token pricing is one line on a Bedrock bill. This models the rest: agent call fan-out, the OpenSearch Serverless capacity floor a Knowledge Base carries whether queried or not, invocation logging, committed throughput and its overflow. The headline is total monthly cost, with the ratio of non-token cost to token cost right beneath it.
Open the model →Not a substitute for an investigation.
The governance tools reason about a landing zone or governance posture in general terms. The calculators model pricing mechanics from values you enter. Neither reads a real AWS bill: no tool here sees your real resources, your real usage, or your real evidence. When the question is about your actual spend, ownership, or a specific disputed number, that is AWS Cost Investigation or Kulshan, not a browser tool.
