Stop treating your AWS bill like a black box.
Clyst turns confusing billing line items into clear visibility, monthly forecasting, and practical recommendations so your team can act before costs get out of control.

The Problem
Cloud bills arrive late, confusing and expensive
Most teams only discover overspending after the month ends. AWS invoices are detailed, but not decision-friendly for fast-moving startups.
Surprises are common
Unexpected spikes from idle resources, data transfer and forgotten environments hit without warning.
Action takes too long
By the time teams identify the cause, the budget damage is already done.
What Clyst Does
Four capabilities. All actionable.
Clyst focuses on outcomes that teams can understand in minutes and act on immediately.
01
Visibility
See month-to-date spend with service- and resource-level cost breakdowns — including your top costliest resources across EC2, RDS, Lambda, and more.
02
Forecasting
Estimate end-of-month costs early and detect if you are trending above budget on day 12, not next month.
03
AI-Powered Recommendations
A local AI model generates recommendations across 6 categories — rightsizing, reserved instances, waste reduction, architecture, and monitoring — ranked by financial impact.
04
Proactive Alerts
Five built-in anomaly detectors: spend spikes, high-concentration services, forecast overruns, orphaned resources, and consistent growth trends. Plus custom rules you define.

FAQ
Frequently asked questions
How does the AWS integration work?
Clyst uses a read-only IAM role in your AWS account. We never request write permissions — we can see your cost and usage data, but we cannot change, delete, or deploy anything on your behalf.
Setup takes under 15 minutes: you create a read-only IAM role in your AWS console, paste the role ARN into Clyst, and data starts flowing. No agents, no SDKs, no infrastructure changes required.
Origin
Why Clyst?
The River Clyst flows through Devon in south-west England, joining the Exe estuary near Exeter. Its name comes from the Celtic word "glast" — meaning clear, clean, bright.
But this quiet river was also the scene of a defining historical moment: the Prayer Book Rebellion of 1549, a popular uprising against religious change in England. The Battle of Clyst Heath was one of its most violent episodes.
Clyst carries both sides: the purity of clarity and the force of transformation.
"Clyst comes from an English river whose name means clarity and purity. But it was also the scene of historical transformation. That's exactly what we do: we bring clarity through the noise — and help turn complex situations into simple decisions."
