We connect with a read-only role that only reads AWS Cost Explorer. That means we see your costs - which services you use, in which regions, and how much you spend each day. We do not see your data, your code, your files, databases, your S3 buckets, or anything running inside your apps. You can check the exact permissions before you turn it on, and switch it off any time from your AWS console.

How do you spot a spike?

We watch your normal spending for a while and learn what's typical for each service. We only alert you when a change is both unusual and big enough in dollars to matter - not just "today costs more than yesterday." You pick the limit, so a small jump on a test account and a huge jump on production are handled differently.

How long does setup take? Do I have to talk to sales?

Less than a minute. You add a read-only role (we give you the CloudFormation), pick where alerts go - Slack, Jira, Email, SMS or a Webhook - and you're done. No file uploads, no onboarding call, no demo.

Why not just use AWS Budgets?

Anomaly-based

Alerts on what’s unusual, not just on a fixed amount.

Ready to use

No Budgets plus SNS plus EventBridge plumbing to maintain.

Easy to act

How much, when, which service, where to check.

In your workflow

Slack, SMS, JIRA, GitHub, Email, Webhook.

Read-only

IAM role for costs reading only, not touching your infra, data or code.

You build. We watch your back.

You moved to the cloud to stop running racks. Cost alerting is the same kind of work - someone has to wire it up, tune it and notice when it silently stops working.

Built for engineers, not finance dashboards.

No new tool to learn, no new tab to keep open. Pick a channel and we deliver alerts where your team already works.
