CostReveal vs CloudZero, a fair comparison
The CostReveal team, , 8 minute read
If you are evaluating cost attribution platforms, CloudZero is one of the names you will meet first. This page compares it with CostReveal on the questions buyers ask most: how each is priced, how each handles Kubernetes and AI spend, and what each does with spend that cannot be attributed. Every statement about CloudZero below comes from CloudZero's own website, linked where it is made. Where we are weaker, we say so.
The short version
CloudZero is an established platform that connects a broad range of cloud, AI and SaaS cost sources, allocates Kubernetes cost down to the pod by the hour, and reports unit costs such as cost per customer. It is priced by custom quote, through a demo.
CostReveal publishes its pricing, starts with a seven day trial you begin yourself, and takes a different position on evidence: every figure carries a label saying what backs it, and spend with no evidence stays visible as unknown rather than being distributed.
Neither is better in the abstract. They give different answers to what a cost report owes its reader.

How CloudZero describes itself
On its pricing page, CloudZero invites you to "request a custom price quote", and describes "a single subscription with all capabilities included, aligned to the scale and complexity" of your AI or cloud environment, including unlimited cost sources, users and dimensions. The way to evaluate it is to book a demo or take a product tour.
Its home page lists connectors including Anthropic, OpenAI, AWS, Azure, Google Cloud, Kubernetes, Databricks, Datadog, New Relic and Snowflake, with more on its integrations page. It answers yes to whether it can show cost per customer, saying it can calculate "cost per customer, per feature, per team, per transaction". It also describes AI Signals for spotting anomalies.
On its Kubernetes page, CloudZero describes "pod-level CPU, memory, and GPU usage automatically mapped to cluster, namespace, workload, label, team, or product", allocation "down to the hour", its CZ Agent factoring GPU requests into allocation, and "distributing shared node costs, including idle overhead, across workloads".
That is a broad, mature offering, and for many large organizations it is the right one.
Pricing
CloudZero is priced by custom quote. You will need a conversation with its team to learn your price.
CostReveal publishes its prices and charges a flat subscription, monthly or yearly, never a percentage of your bill. Paid yearly, a plan costs ten months: two months free.
- Starter, $99 a month or $990 a year: covers up to $25,000 of monthly spend, 5 projects, 10 seats and 5 connectors.
- Pro, $299 a month or $2,990 a year: covers up to $100,000 of monthly spend, 20 projects, 25 seats and every connector.
- Enterprise, from $999 a month: above $100,000 of monthly spend, with unlimited projects, seats and connectors, single sign on and provisioning, and terms set with us.
Every organization starts on a seven day free trial it begins itself: three projects, three connectors and five seats, enough to see AI, cloud and revenue side by side. Starter and Pro are chosen in the product and paid by card, monthly or yearly; Enterprise is set up with us. When a trial ends, figures already read stay readable; connecting and reading pause until a plan is in place.
The reasoning behind flat pricing is structural: a cost tool paid by a share of your spend earns more when you spend more. We would rather the incentive be simple.
Kubernetes: the deepest difference
Kubernetes is where the two approaches differ most, and both are defensible.
CloudZero reports pod level CPU, memory and GPU through its agent, hourly, and distributes shared node costs, idle overhead included, across workloads. The result is a complete per workload picture of what each node cost.
CostReveal starts from the cloud bill too. The OpenTelemetry Collector, installed with the official Helm chart, reports what each workload requested and used of CPU, memory and GPUs, and each node's capacity. Each day, a cluster's billed cost, found on the bill by the cluster's tag, is divided among its workloads: each node's own line, matched by its provider ID, among the workloads on that node, and lines that are no node's, such as disks, across the cluster. Each workload takes the greater of what it requested and what it used, so reserved capacity is paid for by the workload that reserved it, and a GPU node's GPUs are paid for by the workloads that requested them. Owners come from the labels of each pod, its Deployment or other workload, its namespace and its node, and Explore groups spend by cluster, namespace and workload. What no workload took is idle, shown as its own figure and never spread across workloads. Days the cluster sent no metrics are unmeasured, and not divided.
The practical difference: CloudZero gives a finer, hourly picture with idle folded into workload costs. CostReveal gives a daily picture in which idle is a number you can see and shrink, and refuses to divide what it did not measure. If your estate is large and you want every node dollar on a workload, CloudZero's approach fits. If you want to know exactly how much capacity nobody used, CostReveal's idle figure is the one to watch.
AI spend
CloudZero lists Anthropic and OpenAI among its integrations and describes knowing "exactly what each model, provider, and prompt pattern costs across every product and customer segment".
CostReveal reads AI spend through dedicated connections:
- OpenAI, through its costs report: by project, model and line item, with project owners named in CostReveal.
- Anthropic, through its usage and cost reports: by workspace and model, with workspace owners named in CostReveal or read from workspace tags.
- Bedrock, Azure OpenAI and Vertex AI, on the AWS, Azure and Google Cloud bills.
- Usage data, sent from your application with OpenTelemetry, which divides shared Anthropic spend among the customers and features each call was for.
- Custom sources, for any vendor without a connector, such as Mistral or Cohere billed directly: FOCUS files uploaded or sent on a schedule, recorded in the same ledger. CloudZero's equivalent is AnyCost: adaptors you write to convert a bill into its own Common Bill Format.
Both OpenAI and Anthropic admin keys cannot be limited to reading. CostReveal says so before asking for one, only ever reads with it, and stores it encrypted.
What happens to spend nobody can attribute
This is the difference feature tables miss.
CloudZero describes distributing shared costs across workloads. CostReveal takes the opposite position: every figure carries its evidence.
- Direct: what the provider reports itself, such as the service and the model.
- Inferred: what a tag, a named owner or an assign rule names.
- Allocated: what a rule, a cluster's measured usage, Databricks usage or usage data divides.
- Unknown: what no evidence explains yet.
Unknown spend is shown with its amount, and Home names the change that would explain the most of it: tagging the AWS resources of one service, naming the owner of an AI workspace or project, or sending usage data. It is never spread across teams to make a report look complete.
There is no objectively right answer. It is a choice about what a cost report owes its reader: a complete distribution, or a clear line between what was measured and what was not.
How the numbers are checked
CostReveal records every billing line in an append only ledger and checks itself each month. Attribution on every dimension must add up exactly to the ledger. Where the provider offers its own total, such as AWS Cost Explorer, Azure Cost Management, Google's export total, Oracle's Usage API, or Anthropic's, OpenAI's and Datadog's own totals, each month is compared with it: a difference is pending while the month is open, and flagged as a variance once it closes. Where a provider offers no second source, Home says so.
Who should pick which
Consider CloudZero if you want a broad, sales led platform with hourly, pod level Kubernetes allocation that distributes idle overhead, and unit costs across many cost sources in one subscription.
Consider CostReveal if you want published pricing and a trial you start yourself, every figure labelled with the evidence behind it, idle Kubernetes capacity and unexplained spend kept visible, and a monthly check of every figure against the ledger and, where offered, the provider's own total.
Evaluate both if your decision turns on how unattributed spend should be treated. Ask each vendor the same two questions: what happens to spend you cannot attribute, and how do you show your figures match the provider's invoice.
Frequently asked questions
How much does CloudZero cost? CloudZero does not publish prices. Its pricing page invites you to request a custom quote, for a single subscription with all capabilities included.
How much does CostReveal cost? Starter is $99 a month for up to $25,000 of monthly spend, Pro $299 for up to $100,000, and Enterprise from $999 above that. Paid yearly, Starter is $990 and Pro $2,990: two months free. Every organization starts with a seven day free trial.
Can I try CostReveal without talking to sales? Yes. You start the seven day trial yourself and connect a provider. Starter and Pro are chosen in the product and paid by card, monthly or yearly; Enterprise is set up with us.
How do the two handle Kubernetes idle capacity? CloudZero describes distributing shared node costs, idle overhead included, across workloads. CostReveal shows idle capacity as its own figure and never spreads it across workloads.
Does CostReveal cover AI spend? Yes: OpenAI and Anthropic directly, Bedrock, Azure OpenAI and Vertex AI on the cloud bills, and usage data to divide shared Anthropic spend by customer or feature.
Can I move from CloudZero to CostReveal? Each provider is connected to CostReveal directly, and the first read brings in the current month and the twelve before it, where the provider still holds them. AWS needs a new export, created by CostReveal's setup, which AWS fills with earlier billing periods on a support case.
