Plans

Every serverlet is available in several plans, tiered by performance. Each item is explained below.

CPU

Represents the guaranteed compute power for your serverlet under the selected plan. It isn’t a maximum value — if the host server has enough free capacity, your application is allowed to use more resources. The CPU figure itself represents a single vCPU: a value of 0.5 means a guaranteed 50% of one vCPU’s compute time.

Ideally, 1 vCPU would equal 1 processor thread. In practice, however, we often need to run serverlets on physical servers with different CPUs and clock speeds. We’ve had to adjust this figure per physical machine so that individual serverlets have roughly the same guaranteed performance. This value is therefore purely indicative, for comparing guaranteed compute power between serverlets.

RAM

Represents the maximum amount of memory that can be allocated to your serverlet. This memory is reserved and guaranteed for your serverlet.

Storage

Represents the maximum storage size for your serverlet. Storage itself sits on very fast local NVMe SSD drives. This value counts the size of all data in the /srv/ directory. It does not count the size of the serverlet/container environment itself or the /tmp directory. The storage image of the serverlet itself may exceed this value.

Once your allocated space is used up, further disk writes will be refused. Some applications may stop working correctly as a result. Applications that don’t need to write to disk, or that only write to /tmp, will continue to function. We don’t apply any restrictions on our end, so you don’t need to worry about us shutting down your site because of this.

The allocated disk space is entirely yours, and it’s up to you what you use it for, as long as it doesn’t violate the laws of the Czech Republic or common decency. We don’t distinguish between using it for a website and using it as private file storage.

Supported software

Every customer’s needs are different, and so are the needs of different applications. We don’t apply any restrictions or differences between plans on our end. However, lower-tier plans may not have enough resources to run every application. See the plan overview and recommendations below — these are only our recommendations, not binding limits.

Hourly billing

Serverlets are billed based on actual usage time. An hourly rate is charged for every hour of serverlet uptime, per the selected plan.
