DevOps utilities and calculators
Free, fast, browser-only DevOps tools. No sign-up, no data sent anywhere. Built to replace the half-broken, ad-infested ones that rank for these queries.
CIDR Calculator
Calculate network range, usable IP count, subnet mask, and broadcast address from a CIDR block.
JWT Decoder
Paste a JWT and see the header, payload, and signature, plus human-readable expiry and issued-at.
Base64 / URL
Encode or decode base64 and URL-safe strings. Handy for secrets, Kubernetes manifests, and API debugging.
UUID / Secret
Generate UUIDs (v4, v7), random hex tokens, and base64 secrets suitable for Kubernetes secrets or API keys.
Cron Parser
Translate cron expressions to human-readable schedules and preview the next run times.
K8s Resources
Size CPU and memory requests / limits for a Pod based on workload characteristics, replicas, and headroom.
YAML / JSON
Paste YAML or JSON to validate, pretty-print, and convert between the two. Runs entirely in your browser.
