EC2 & EBS waste alerts that live in Slack

Your idle EC2 instances are burning $140/month each

SaneCost detects idle instances and orphaned EBS volumes, then messages the owner directly in Slack. No dashboard to check. No login to remember. Just an alert where your team already works, with a button to act.

You're not alone

If your AWS bill feels wrong, it probably is. The industry wastes $44.5 billion a year on idle cloud infrastructure. Most teams don't even know it's happening.

Don't take our word for it:

$44.5B in cloud waste projected for 2025 — Harness 32% of cloud budgets wasted on idle resources — DataStackHub 60%+ of waste from idle & overprovisioned compute — CloudZero

What it does

Idle instances and orphaned volumes, flagged to the right person

EC2 & EBS Detection

Checks CPU utilization across your EC2 fleet every 30 minutes and flags unattached EBS volumes wasting storage costs. Filters out batch jobs, periodic workloads, and freshly-launched instances. You set the CPU threshold and observation window.

▶ Verdict: idle — $140/mo recoverable

Your rules, not ours

You define what "idle" means for your infrastructure. Set your own CPU thresholds, observation windows, and instance exclusions. Every team's workload is different — SaneCost adapts to yours, not the other way around.

Slack Alerts

Posts to your team channel with full context — instance ID, type, region, daily cost, and how long it's been idle. If the instance has an Owner tag with an email, the owner gets a direct DM too.

Multi-Account Coverage

Scans EC2 instances and EBS volumes across all regions in every connected AWS account. Connect as many accounts as you need to one Slack workspace. Alerts are deduplicated — you'll never get spammed about the same resource.

How it works under the hood

Algorithms first, AI when it helps

Core detection is algorithmic — CPU thresholds, time windows, cost calculations. No black box. AI steps in only for edge cases: refining confidence on ambiguous patterns and extracting owners from messy tags. Every alert ships with raw data so you can see exactly why it was flagged.

You decide. We never act without your click. But we'll nudge you towards savings like nobody else can.

AI-assisted recommendations may occasionally be inaccurate. Every alert includes the data you need to decide — one glance, one click.
