YAML ⇄ JSON

Validate manifests before they hit the cluster, or flip between formats. Errors show the exact line.

Manifest builder

Fill the form, get a clean Deployment + Service. No more copying half-remembered YAML from old repos.

Helm builder

Compose a complete, installable chart — any workload kind, with volumes, secrets, storage, scaling and networking — then download it as a real .tgz Helm package. Built entirely in your browser.

kubectl cheats

Click any command to copy it. Search by what you're trying to do — “debug”, “logs”, “drain”…

Cron explainer

Paste a 5-field cron expression (like a CronJob schedule) to see it in plain English and its next run times.

Kubernetes resource units

Millicores and Mi/Gi trip everyone up in requests & limits. Type a value, see every equivalent.

JWT decoder

Decodes header and payload locally — the token never leaves your browser. Signature is not verified.

Base64

Encode values for Secrets, decode what's already in the cluster. UTF-8 safe.

Epoch time

Turn timestamps from logs into human dates and back. Seconds or milliseconds auto-detected.

JSON formatter

Pretty-print or minify JSON. Invalid input is echoed back with the offending line highlighted.

URL / query string

Percent-encode or decode text, and explode any URL or query string into its parameters.

UUID v4 / ULID

Generated with crypto.getRandomValues. ULIDs are time-sortable — the first 10 chars encode the millisecond.

Hashes

SHA-1, SHA-256 and SHA-512 of the text below, computed live via WebCrypto. Hex output.

Line diff

Line-level diff via longest-common-subsequence. Red is removed, green is added.
