Infrastructure Calculators
Free calculators for Kubernetes, AI infrastructure, GPU hosting, storage planning, and more.
kubernetes
Kubernetes Cluster Cost Calculator
Calculate the monthly cost of running a Kubernetes cluster on Hetzner Cloud. Choose server types for control planes, workers, and load balancers with HA mode.
storage
Longhorn Storage Calculator
Calculate the total storage required for Longhorn distributed block storage, including replica overhead, snapshot retention, and S3 backup sizing on Hetzner Object Storage.
ai-gpu
AI Model VRAM Calculator
Calculate the GPU VRAM required to run any LLM locally or on cloud GPU. Supports all quantization levels — FP32, FP16, INT8, INT4, and GGUF variants.
ai-gpu
GPU Hosting Cost Calculator
Compare GPU cloud rental costs across RunPod, Lambda Labs, and Vast.ai. Calculate monthly spend for LLM inference, fine-tuning, and ML training workloads.
kubernetes
Kubernetes Node Sizing Calculator
Calculate the right number and size of Kubernetes worker nodes for your workloads. Supports Hetzner Cloud and Vultr with verified pricing.
kubernetes
k3s Resource Calculator
Calculate RAM and CPU requirements for a k3s cluster. k3s has 5–10× lower overhead than full Kubernetes — see exactly how much your server and agent nodes need.
kubernetes
Kubernetes Certificate Expiry Calculator
Calculate when your Kubernetes certificates expire and whether you need to renew them. kubeadm certificates are valid for 1 year — missing renewal breaks the cluster.
observability
Kubernetes Observability Stack Sizing Calculator
Size your Prometheus, Grafana, Loki, and Alertmanager stack. Calculate RAM, disk, and CPU requirements based on your cluster size and retention period.
kubernetes
etcd Backup Size Estimator
Estimate the size of etcd snapshots and monthly backup storage for your Kubernetes cluster. Plan S3 storage costs for etcd backup retention.
kubernetes
Kubernetes Upgrade Path Planner
Plan your Kubernetes upgrade path from any version to any version. Kubernetes only allows upgrading one minor version at a time — calculate the number of hops and total time estimate.
kubernetes
Kubernetes Autoscaler Threshold Calculator
Calculate the right HPA (Horizontal Pod Autoscaler) CPU and memory thresholds for your Kubernetes workloads. Get absolute target values in millicores and MiB.
kubernetes
Temporal Workflow Resource Calculator
Calculate Kubernetes resource requirements for a self-hosted Temporal workflow engine. Size the History, Matching, Frontend, and Worker services plus the PostgreSQL persistence layer.
observability
Prometheus Storage Calculator
Calculate Prometheus disk and RAM requirements based on active time series count, scrape interval, and retention period. Includes TSDB head, WAL, and chunk cache sizing.
observability
Loki Log Storage Calculator
Calculate Grafana Loki disk, S3 storage, and RAM requirements based on pod count, log rate, compression ratio, and retention period.
observability
Grafana Resource Sizing Calculator
Calculate Grafana RAM, CPU, and storage requirements based on dashboard count, concurrent users, alert rules, and data source count.
observability
Tempo Tracing Storage Calculator
Calculate Grafana Tempo or Jaeger distributed tracing storage requirements. Size disk, S3, and RAM based on spans/sec, bytes per span, sampling rate, and retention.
networking
Service Mesh Overhead Calculator
Calculate the RAM, CPU, and latency overhead of running Istio, Linkerd, or Cilium as a service mesh. Compare sidecar vs eBPF approaches per pod and cluster-wide.
networking
Cilium Resource Requirements Calculator
Calculate Cilium CNI agent RAM and CPU requirements per node. Includes Hubble observability overhead, WireGuard encryption, and BPF map memory for network policies.
networking
Kubernetes Bandwidth Estimator
Estimate internal pod-to-pod bandwidth, external egress, and recommended NIC size for your Kubernetes cluster. Accounts for service mesh overhead and Hetzner egress pricing.
