Billing

Zuletzt aktualisiert am

STACKIT uses a transparent, usage-based pricing model. You are billed only for the resources you consume, with no hidden fees for feature activations. For detailed rates, refer to the STACKIT pricing list

CDN costs are primarily determined by outbound data transfer (traffic) and the use of the Image Optimizer.

You are billed exclusively for traffic delivered from CDN edge locations to your end users.

  • No request fees: Transaction-based costs do not apply, regardless of request volume.
  • Free ingress: Data transfer from your origin server to the STACKIT Network is free.
  • Included features: Managed SSL certificates (Let’s Encrypt) and cache purging are available at no additional cost.

Billing is calculated automatically based on the geographic region of the user requesting the data.

The Image Optimizer incurs costs based on active usage duration.

  • Hourly billing: You are billed only for the hours the Optimizer is enabled for your distribution.
  • Cost cap: Monthly costs are capped. Once you reach the maximum amount in a billing cycle, further use of the Optimizer is free for the remainder of that month.

Web Application Firewall (WAF) costs depend on your selected security tier and the volume of incoming requests.

The Basic tier provides standard security rule sets and is included with your distribution.

  • Request allowance: Includes a free tier of up to a defined number of requests.
  • Overage billing: Requests exceeding the free limit incur charges based on predefined request buckets.

The Premium tier provides advanced security capabilities and premium rule sets.

  • Base fee: A fixed, recurring monthly charge to enable the Premium tier.
  • Request billing: All requests processed by the Premium WAF are billed on a per-request basis in addition to the base fee.

WAF log fields are integrated into your existing CDN Logs at no additional cost, regardless of your active WAF tier.
