For platform teams running several clouds and LLM providers
Give every engineer the cost context of a FinOps team.
Costory joins your cloud, LLM and data-cloud bills with your telemetry, allocates every euro with rules you version in git, and answers where your engineers work: Claude, Cursor and Slack. From 250€/month (~$300). Never a % of your bill.
30-day free trial, no credit card. Connect in under 30 minutes, get your first optimization recommendation the next day. Read-only on your cloud.
It starts in Slack, not in a dashboard.
One person curious about cost? Ask Claude and DIY. A whole org that needs the same number? Use Costory.
If one person in your company looks at the cloud bill, connect Claude to your billing API. It works, and you don’t need us. Once you start to slice your engineering team into multiple squads or tribes, and their leads and finance rely on the same number, it becomes a data engineering problem: one dataset, one allocation logic, one definition of “cost per customer”. That’s what Costory is.
Built by data engineers, on a modern data stack.
Every bill (AWS, GCP, Azure, Snowflake, Databricks, OpenAI, Anthropic and more) is normalized into one model on BigQuery and joined with your context: telemetry, CI, dbt, product events, business metrics. It’s also why we can charge a flat price: processing your bills costs us little, and we pass that on.
Four reasons to choose Costory
01
Allocation that holds in a large org.
Write allocation rules as YAML in git. Map your Backstage or CMDB catalog onto the bill, split shared costs by weight or by real usage, and date every entry so a reorg never rewrites last quarter. Reviewed in a PR, backfilled over your full history, managed with Terraform.
02
Everything included, at a flat price.
Unlimited users and sources. Notebooks, unit economics with formulas (cost per ticket, per customer, per feature), formula alerts you can backtest, budgets, Slack alerts and the MCP. In every plan, from 250€/month.
03
The FinOps harness.
An agent with the skills, the company context and the loops to monitor, investigate, report and recommend. Ask it in Claude, Cursor, Slack or Dust. Some teams only use Costory through Claude. Loops are Scouts: assign one to your reports and alerts, give it instructions in plain text, and it adds the cause, the owner and the next step to every delivery. It never touches your code base: it hands each saving to your coding agent.
04
Open by default.
Public API (OpenAPI). Export allocated data to your dashboards, your IDP (Backstage, in beta), BigQuery, Iceberg/Parquet or your finance systems. No lock-in.
TWO WAYS TEAMS COME TO COSTORY
Moving from a FinOps tool, or asked to build one?
Try it next to the tool you have.
Costory reads billing exports directly from each provider, read-only, so it runs alongside your current tool for the 30-day trial.
Allocation rules are YAML in git: reviewed in a PR, managed with Terraform.
From 250€/month, never a % of your bill.
Build on Costory, not from scratch.
One engineer with Claude and a billing API gets a useful dashboard in an afternoon. That part is free, and we recommend it. A tool the whole team can trust takes weeks, then maintenance forever. We built that part. You keep control: YAML, formulas, the API, Terraform, and export to your own warehouse.
Clear limits
What Costory does not do
Costory does not buy Reserved Instances or Savings Plans for you. The agent recommends; your team decides.
It does not apply automated rightsizing or change resources for you.
It does not promise a savings percentage. Recommendations come with an impact estimate from your own usage.
It never gets write access to your cloud accounts. MCP actions create Costory objects only: alerts, reports, dashboards and events.
It never charges a percentage of your bill.
Start at 250€/month (~$300). Pay more only when you use more. Never a % of your bill.
