Paste logs into AI without leaking secrets.
Tools, cheatsheets and prompts for Kubernetes, cloud and CI/CD. Everything runs in your browser and the code is open source.
Tools
- Kubernetes manifest checkerPaste YAML and get warnings for missing limits, :latest images, root containers and other common mistakes.
- Pod status explainerPaste kubectl describe pod and find out why it is in CrashLoopBackOff, ImagePullBackOff, Pending or OOMKilled, and what to run next.
- kubectl neat: clean exported YAMLStrip status, managedFields, cluster-assigned IPs and default values from kubectl get -o yaml, and get a manifest you can commit.
- Kubernetes resource calculatorConvert CPU and memory quantities, see how many pods fit on a node, and total the requests in your manifests.
- Kubernetes Secret decoderDecode every value in a Secret at once, spot trailing newlines, or create a Secret from KEY=value lines.
- Kubernetes manifest & kubeconfig redactorMask Secret values, kubeconfig tokens, cluster endpoints and IPs before you paste YAML into an AI chat or a ticket.
- Label selector testerCheck which pods a selector matches, and why the others do not. Accepts kubectl --show-labels output.
- RBAC explainerRead Roles and bindings in plain words: who can do what, where, and which permissions are risky.
- Service account kubeconfig generatorGet a script that creates a service account with the right RBAC and writes a kubeconfig for it. The token never touches this page.
- NetworkPolicy explainerSee what a NetworkPolicy allows in plain words, and test whether one pod can reach another.
- kubectl command builderBuild kubectl commands for logs, exec, port-forward, rollouts, debugging and more, with each flag explained.
- YAML ↔ JSON converterConvert YAML to JSON and back, including multi-document YAML.
- JWT decoderRead the header and claims of a JSON Web Token and check when it expires.
- Base64 encode / decodeEncode or decode Base64 with UTF-8 support, handy for Kubernetes Secret values.
- CIDR / subnet calculatorNetwork range, usable hosts (including Azure’s 5 reserved addresses) and subnet splits.
- Cron expression explainerRead a cron schedule in plain words and see the next run times in UTC or local time.
AI prompts
- Debug a pod in CrashLoopBackOffFind the root cause of a crashing pod from its describe output, logs and recent changes.
- Review a Kubernetes manifestGet a security and reliability review of a Deployment, StatefulSet or Helm-rendered YAML.
- Write a blameless postmortemTurn an incident timeline and notes into a structured, blameless postmortem document.
- Write a PromQL query or alertDescribe what you want to measure and get a working PromQL query, with an alert rule if needed.
Cheatsheets
- kubectlDay-to-day kubectl commands for inspecting, debugging and fixing workloads.
- openssl and TLSInspect certificates, check expiry, test TLS endpoints and convert between PEM, PFX and DER.
- PromQLPromQL queries for request rates, error ratios, latency percentiles and Kubernetes resource usage.
