Features
Affordable spend management for AWS
Hourly anomaly detection that learns your spend, budget alerts and a spend timeline with alert overlay — secure, read-only, and the timely warnings you need before the bill goes haywire, without an enterprise FinOps suite.
Anomaly detection within the hour
EchoWatch checks your spend every single hour. Once it has learned your normal pattern, any hour where spend deviates beyond two standard deviations triggers an alert — naming the service driving the jump. Catch a runaway instance in the hour it happens, not at month-end.
Learns your spend profile
For the first couple of weeks EchoWatch quietly learns each account's normal daily spend. After that it only speaks up on a genuine anomaly, so you get sharp signal instead of noisy false alarms. Budgets protect you from day one while it learns.
Secure, read-only access
Connect with an External-ID-scoped cross-account IAM role — no access keys change hands, EchoWatch never gets write access and never touches your resources. We only read Cost Explorer, and any stored credentials are encrypted at rest. Revoke any time by deleting one stack.
Spend timeline with alert overlay
See daily spend broken down by service and 30-day trends in one calm dashboard, with every detected anomaly marked right on the chart — so you can see exactly what your costs are doing and when they spiked.
Budget alerts & guardrails
Set a monthly budget for a whole account or a single service. We track month-to-date spend on every hourly sync and warn you at your threshold, then again the moment it's exceeded — no dashboards to babysit.
Alerts where you work
Cost alerts route to Slack, email and SMS with per-severity rules, and can page an on-call rotation — the same trusted engine also does uptime and CloudWatch monitoring if you want it.
How we compare
The right-sized cost monitor for startups
Enterprise FinOps tools are overkill and AWS Budgets alone can't spot an anomaly. EchoWatch sits right in between.
