Google Cloud Capacity Planner

Overview

Google Cloud Capacity Planner is a cloud tool for tracking and forecasting Google Cloud resource use to guide capacity and quota planning. It is best suited to teams already managing Compute Engine and related resources in Google Cloud. Its focused forecasts, quota automation, and no-additional-cost price make it useful for short-term planning, but Preview status and gaps in forecast coverage limit its reach.

It covers Compute Engine instances, Persistent Disk and Hyperdisk volumes, GPUs, TPUs, and Cloud Storage bucket egress bandwidth. Historical usage reaches back up to two years; forecasts extend up to six months, and historical forecast snapshots cover up to one year. Usage is sampled every five minutes and displayed within 24 hours, while Overview insights update at least every 48 hours. That cadence supports ongoing planning, not minute-by-minute capacity response.

The product is in Preview under Pre-GA terms, is provided as is, and may have limited support. Only eligible organizations can use it; some may need to request access through a technical account manager or Google Cloud sales. A Google Cloud project is required, and viewing access is controlled through Google Cloud IAM permissions, including the Capacity Planner Viewer role.

Key features

Usage views and forecasts

Compute usage can be viewed at the P50, P75, and P99 percentiles, giving teams several ways to assess demand rather than relying on one usage level. Cloud Storage bucket usage is available at P100 only. Forecasts combine linear and superlinear models, and add yearly seasonality for scopes with at least two years of usage history. That makes longer histories more useful for recognizing recurring annual patterns.

Forecast coverage has meaningful boundaries: forecasts are not supported for Spot VMs or Cloud Storage buckets, and bucket history is unavailable before December 1, 2025. Teams relying on those workloads will need another basis for forecasting them.

Quota and reservation planning

The quota adjuster can automatically submit quota increase requests as a project approaches a limit, but only when there is sufficient usage data and the resource is supported. It can reduce manual follow-up for eligible quotas; it is not a blanket quota-management service.

Future reservation requests can provide high-level capacity assurance for Compute Engine instances or GPUs. Approval also commits the user to pay for the requested resources throughout the full reservation period, whether or not they are used. That commitment makes reservations a deliberate capacity purchase, not a risk-free forecast outcome.

Exports and API

Teams can export usage and forecast data as CSV, or use the API to send it to Cloud Storage or BigQuery. The Capacity Planner REST API also provides programmatic access at project, folder, and organization scopes, which suits organizations that need to incorporate planning data into broader workflows.

Pricing

Capacity Planner — free. The free plan has no additional charge for using Capacity Planner; Google Cloud resources used with it remain billable separately. It is available to eligible organizations, requires a Google Cloud project, and is marked Preview. There are no paid Capacity Planner tiers to compare, so the main trade-offs are eligibility, Preview support limits, and the cost of the underlying cloud resources rather than a subscription cap.

Platforms

Capacity Planner is available through the web and API as a cloud deployment. Its short-term planning horizon and Google Cloud-specific resource coverage make it a fit for cloud capacity work rather than general device or infrastructure management.

Who it's for

Choose Capacity Planner if your team needs a no-additional-cost way to inspect Google Cloud usage, forecast near-term demand, and support quota or reservation decisions across projects, folders, or an organization. It is less suitable when forecasts for Spot VMs or Cloud Storage buckets are central, when broad support commitments are essential, or when you need a long-range planning horizon beyond six months.

Pros and cons

Pros

• No additional Capacity Planner charge: teams can use its planning features without a separate subscription, while paying for the Google Cloud resources they consume.
• Useful planning depth: up to two years of history, six-month forecasts, percentile views for compute, and historical forecast snapshots support review of changing demand.
• Operational links: quota request automation and CSV, Cloud Storage, BigQuery, and API access connect planning to follow-up work.

Cons

• Preview constraints: Pre-GA terms, limited support, and organization eligibility can make it a poor fit for teams that require mature product commitments.
• Incomplete forecast coverage: Spot VMs and Cloud Storage buckets lack forecasts, and bucket history starts only on December 1, 2025.
• Reservation costs are binding: approved future reservations require payment for the full period even if capacity goes unused.

Alternatives

IT Capacity Management Software is the category directory for comparing capacity-management options. Consider IBM Capacity Management Analytics if you need a paid offering with Linux, macOS, self-hosted, web, and Windows platforms, or a z/OS edition. ITRS Capacity Planner is another paid option with Android, iOS, Linux, web, and Windows platforms.

Rocket EDX is a paid alternative available via API, Linux, web, and Windows, with variable usage or fixed-price subscription. Hyperview may suit teams seeking a paid option with a 30-day free trial and Android, API, iOS, Linux, web, and Windows access; its trial includes all features and requires no credit card. FNT Command offers a paid Asset Inventory plan at €99 a month, billed annually, with per-user pricing, location and lifecycle management, reports, and role and permission features.

EcoStruxure IT is a paid option with Android, iOS, and web platforms. Kentik Network Capacity Planning offers a 30-day free trial and a Pro plan at $2,000 a year; it is available through API and web. Device42 is another paid option, available on web, Windows, macOS, and Linux.

Verdict

Google Cloud Capacity Planner is a sensible choice for eligible Google Cloud teams that want free, resource-specific usage forecasts and a route from planning to quota requests and reservations. Its strongest case is practical planning without a separate tool charge. Look elsewhere if you need dependable Pre-GA support, forecasts for Spot VMs or Cloud Storage buckets, or want to avoid the payment commitment attached to approved reservations.
