Useful tools,
all in one place.
Encoding, data, security, time, automation, and cloud-native utilities — mostly browser-local.
Base64 Encoder & Decoder
Encode Unicode text to Base64 or decode Base64 safely in your browser. No upload, signup, or server processing.
Runs locally ↗EncodingBase64 File Encoder & Decoder
Turn a file into Base64 or download a Base64 data URI as a file. Processing stays completely on your device.
Runs locally ↗Time & AutomationCron Expression Parser
Explain standard five-field cron expressions in plain English and validate common ranges locally.
Runs locally ↗Cloud NativeHelm Template Debugger
Render and lint a Helm template with the real Helm engine, precise errors, and an ephemeral server-side workspace.
Backend check ↗SecurityJWT Decoder & Expiry Checker
Decode JWT headers and claims, inspect timestamps, and check expiration locally. Decoding does not verify the signature.
Runs locally ↗Cloud NativeKubernetes Manifest Validator
Run a fast Kubernetes manifest preflight for YAML structure, required identity fields, metadata, and common safety issues.
Backend check ↗Cloud NativeKubernetes Secret Decoder
Decode every value in a Kubernetes Secret manifest locally and identify invalid Base64 without exposing credentials.
Runs locally ↗SecurityPEM Certificate Inspector
Inspect an X.509 PEM certificate, validity dates, subject, issuer, serial number, and SHA-256 fingerprint locally.
Runs locally ↗SecurityRSA Certificate Generator & Parser
Generate a self-signed RSA X.509 certificate and parse RSA certificates or keys online. Generated material is returned once and never stored.
Backend check ↗Time & AutomationUnix Timestamp Converter
Convert Unix seconds or milliseconds to local and UTC dates, or turn a date into a timestamp instantly.
Runs locally ↗DataYAML Formatter & Validator
Catch common YAML indentation and structure errors, then normalize readable configuration locally in your browser.
Runs locally ↗DataYAML to JSON Converter
Convert common YAML documents to JSON and JSON back to readable YAML without uploading configuration data.
Runs locally ↗Cloud NativeHelm Values Diff
Compare two Helm values files line by line locally before upgrading a release or changing environments.
Runs locally ↗SecuritySHA Hash Generator
Generate SHA-256, SHA-384, SHA-512, or SHA-1 digests from text and local files in your browser.
Runs locally ↗EncodingURL Encoder & Decoder
Encode URL components or decode percent-encoded text locally, with clear handling for spaces and Unicode.
