Subscription plans¶
When signing up for the CrateDB Cloud service, you have a choice of six different subscription plans. Each plan is preconfigured for different use cases, depending on what your storage, and computation needs are. At the same time, the plans also offer elasticity, since your use case may change. Within a given plan you can horizontally scale the compute capacity of your cluster up or down by adding or subtracting nodes. Limited vertical scaling is also possible, with storage scaling (up only). For information on how to do this, refer to our scaling guide.
The nature of our plans depends on the method of your subscription. We will first explain the plans for the recommended subscription method, subscribing and deploying a cluster directly. Subsequently, we will provide some more detailed information regarding plans and billing for subscriptions via our Marketplace SaaS offers.

CrateDB Cloud subscription plans¶
The standard CrateDB Cloud deployment process offers six subscription plans, labeled:
CRFREE, CR0, CR1, CR2, CR3, CR4
Each of these plans consists of two dimensions: compute and storage. The compute configuration is set for each plan, but can be scaled horizontally by adding or subtracting nodes during or after deployment. Storage is configured separately: on deployment you can set the desired storage capacity for your cluster, within the range of storage capacity options provided for that plan. Storage can also be scaled up, but cannot be lowered after that. To view the current plans, prices, and compute and storage ranges, refer to our pricing page. The exceptions to this are CRFREE and CR0, which cannot be scaled, or reconfigured.
For details on signup, cluster configuration, and cluster deployment, you can make use of our deployment tutorial.
Note
CrateDB Edge works differently. Since it allows hosting CrateDB Cloud on your local or self-service Kubernetes stack, there is no need for different subscription plans. You can combine CrateDB Edge with any suitable hardware configuration that works for your use case.
Although you can scale your cluster from a single node to as many nodes as desired, only clusters containing 3 or more nodes are covered by our 24/7 support. You can find our CrateDB Cloud terms and conditions in our SLA.
CRFREE¶
This plan is aimed at new users who want to test and evaluate CrateDB Cloud and is perpetually free to use. Every user can deploy one free tier cluster in their organization without adding a payment method. This plan also doesn’t consume any Free Credit that you may have available. They are limited to one node with 2 CPUs, 2 GiB of memory, and 4 GiB of storage.
CRFREE was made for active testing and evaluation, which is why any CRFREE cluster is suspended after 7 days of inactivity. When this happens, the user is notified via email.
CR0¶
The CR0 plan, or Shared-resource cluster, is a special category of cluster that allows better utilization of resources. These clusters share compute and storage resources with other clusters in this category. Because of this, they offer a more cost-effective solution for smaller teams and experimental deployments of low-traffic applications. They are limited to one node with 2 CPUs, 2 GiB of memory, and 4 GiB of storage.
CR1-CR4¶
These are our base plans that offer the best performance, and the biggest flexibility. Their specs start from 1.75 CPU, 7 GiB RAM, and 32GiB storage all the way to 14 CPU, 55 GiB RAM, and 512 GiB storage per-node. These plans can be scaled to up to 9 nodes. If you need more nodes than this, feel free to contact us at any time.
Warning
An even number of nodes can be used for testing and development without issue, but is not recommended for production workloads, due to the risk of split-brain syndrome.
Subscription plan regions¶
We currently offer three regions for our subscriptions: one from AWS (West Europe) and two from Azure (East US 2 and West Europe). You can use any subscription plan in any region. Note that prices for a given plan differ depending on the region you select. We also accept region requests, in case your preferred region is not currently available.
Marketplace offer¶
If you have an existing Azure/AWS marketplace account and want to subscribe to CrateDB Cloud using that, you can. The principles are the same as with credit card subscription, which allows maximum flexibility regarding deployment and scaling up/down:
Usage is billed based on consumption
Billing is done in $0.001 increments for the compute + storage usage
For details visit Azure, or AWS marketplace deployment tutorials.
The CrateDB Cloud Contract¶
The CrateDB Cloud Contract allows you to pay for a full year’s worth of the service of your choice in advance. Depending on the specifics of the contract chosen, it may be possible to negotiate a discount based on the up front payment. The CrateDB Cloud Contract is only available via our supported cloud providers on the SaaS Marketplaces. For more information, contact our Sales team.
