Now open to early adopters

Cut cloud waste. Not your speed.

KÖLTTÖ connects to OCI and AWS to surface hidden overspend and rank the optimizations that matter — in one portal. Azure, GCP, Linode, and DigitalOcean are next.

Your cloud bill,
in one place

Connect a cloud. See spend, inventory, and ranked estimated savings in the portal — without living in the provider console.

Always-on cost monitoring

KÖLTTÖ syncs billing and inventory so you can watch spend trends, services, and resources in one place — not after the invoice lands.

Ranked savings recommendations

Idle compute, unused storage, oversized shapes — opportunities are ranked by estimated impact so you know what to fix first.

Spend analytics

Slice cost by service, account, and region. See where money went this month — and how it compares to last.

Multi-cloud, starting now

See OCI and AWS spend in one portal, with a provider filter on the dashboard. Azure, GCP, Linode, and DigitalOcean use the same model when they ship.

Budgets & alerts

Set spend caps and get notified as usage approaches the limit — so finance and engineering can act before the month closes.

Inventory & exports

See what you are running, with utilization context for rightsizing. Export cost data as CSV.

Connect, sync,
then cut waste

Private beta is a portal for OCI and AWS: connect a cloud, sync spend and inventory, then work ranked opportunities. The AI preview below is a roadmap concept — not available in beta today.

KÖLTTÖ AI — preview Coming soon
Why did our EC2 bill jump 40% last week?
Your data-pipeline-prod EC2 fleet scaled from 8 to 24 instances on April 14 after a queue-depth spike, then stayed large while CPU sat near 12%.

Rightsizing back toward steady demand is an estimated ~$2,840/mo on this example — the kind of lead Opportunities already ranks from inventory and utilization.
Show me what we could rightsize
Illustrative top leads from resources KÖLTTÖ inventories today:

1. ec2-batch-workers — m5.2xlarge → m5.xlarge est. -$1,900/mo
2. unattached EBS — 23 volumes with no attachment est. -$1,100/mo
3. oci-compute-ashburn — idle shapes under 3% util est. -$860/mo

Connect OCI or AWS

Link a tenancy or account with read-only credentials. No agents, no code changes, no infrastructure to manage. More clouds are on the way.

KÖLTTÖ syncs your estate

We pull billing data, inventory, and utilization metrics — then rank the highest-impact estimated savings on the Opportunities page.

Explore, then act

Use dashboards, spend analytics, budgets, and inventory in the portal. Plain-English Q&A and a guided planner stay on the roadmap.

Koltto AI next

Coming next — not in beta yet

These are planned. They are not available in private beta today. We’d rather show them here than sell them as live.

Soon

Koltto AI

Ask cost questions in plain English, or chat about spend in the portal. The bot and analyzer are next — not in private beta today.

Soon

Forecaster

A dedicated view of where the month and quarter are heading — separate from today’s budgets and alerts.

Soon

More clouds

Same connect → sync model. Azure and GCP next, then Linode and DigitalOcean — all in the same portal.

Soon

Optimization planner

Turn ranked opportunities into an implementation plan. No one-click remediations in the portal yet.
