StackAlert watches your AWS costs against a 7-day baseline and pings you the moment something spikes — on Telegram, Slack, Teams, or PagerDuty. Before your bill arrives.
"Our Lambda hit $47,000 in one weekend because of a single line of code. AWS Budgets sent an email — after we'd already been billed." — r/aws
The problem
AWS Cost Explorer shows yesterday's data. Budgets alert on monthly thresholds. Cost Anomaly Detection needs 10 days to warm up per service. A single bug can run up thousands while you sleep.
Features
Not another dashboard to check. Real-time notifications to wherever your team already lives.
Every AWS service gets its own 7-day rolling baseline. Lambda, EC2, RDS, S3 — each tracked independently. No more "is this spike normal?" guessing.
Runs entirely inside your AWS account. Your cost data never touches an external server. GDPR compliant by architecture.
Morning summary of yesterday's spend — every service, sorted by cost. Start your day informed.
Install as part of your existing IaC stack. One import, one deploy. No separate signup, no agent to run, no YAML to write.
Monitor multiple AWS accounts via IAM role assumption. One StackAlert instance, all your accounts.
Alert channels
7 notification channels. Mix and match. No lock-in.
NOTIFY_CHANNELS="telegram,slack,pagerduty" // mix and match, comma-separated
How it works
No SaaS account to create. No agent to run. Just your AWS account.
Add the StackAlert construct to your existing IaC stack. Configure your notification channels and thresholds.
The Lambda runs every 6 hours, building a 7-day rolling average per service. No warmup period — works from day one.
Instant push notifications on Telegram, Slack, or wherever. Includes service name, cost, baseline, and projected daily total.
Coming soon
The open-source Lambda handles alerting. The dashboard gives your team a 90-day anomaly history, multi-account overview, and notification management — without touching environment variables.
