Features

See it, get alerted, cut it

Connect your cloud and AI providers. CostMon shows you where the money goes. It alerts you when a service breaks its baseline, and finds what you can cut.

Hear about a spike while you can still act on it.

Budgets, alerts, and anomaly detection

CostMon compares each day's spend against its own recent baseline. A default rule watches every connected source from the day you sign up.

  • A default rule is active at signup, watching every connected source.
  • Every alert lands in the in-app feed. Add an email, Slack, or webhook channel to get it there too.
  • Budgets warn at 80% and 100% of the limit you set, with a burn-down projection.
  • Scoped rules can watch one provider source, service, or tag.

Anomaly detectionSample data
Sample data: a daily baseline breaks, and an alert fires.

Savings recommendations, graded by confidence

CostMon scans your cost data for patterns that often mean waste. It flags possible idle services, SKUs that cost more than their peers, and commitment gaps. Each finding carries a confidence grade.

  • Flags possible idle services, rightsizing candidates, and commitment gaps.
  • Grades each finding: high, medium, or low confidence.
  • Names the service, commitment, or SKU behind each finding.

Cost buckets by team or product

Allocation rules group spend by team, product, or customer. A rule matches on the provider source, the service, the connector, or any tag you already send. Spend that no rule matches stays visible as unallocated.

  • Rules match on source, service, connector, or tag.
  • Unallocated spend stays visible in its own line.
  • A showback view lists each bucket's spend, its share, and its daily trend.

Spend by bucketSample data
Sample data: one month of spend split into four buckets.

One live total, every provider

CostMon adds every connected bill into a single running total. Finance and engineering read the same figure. It updates every time a connector syncs.

  • Combines AWS, Anthropic, and every other connected provider into one figure.
  • Updates automatically as each connector syncs.
  • Shows the change against the previous period. A jump stands out right away.

All spendSample data
Sample data: one normalized total across four connected providers.

Know what one customer actually costs to serve.

Cost per customer

You define the unit: active customers, orders, or seats. CostMon divides spend by that unit for any period you pick.

  • Record the unit's value for each period, in the app or over the API.
  • Splits cost per unit by any allocation dimension you already use.
  • Charts cost per unit over time, so a climb shows up early.

Flat pricing, always

You pay a flat monthly rate, never a percentage of what you spend or save.

Connectors

Cloud, AI, and SaaS: all in one place

AWS, GCP, and Azure for cloud. Anthropic, OpenAI, Amazon Bedrock, Vertex AI / Gemini, and Helicone for AI and LLM spend. Snowflake and Databricks for the data cloud. Datadog, GitHub, and Vercel for the rest of the stack. Add CSV import for any tool without a native connector. That's 14 connectors, all normalized into the same unified view.

Connect a provider and CostMon builds a daily baseline for it. From there, a spike reaches your team as an alert.
