About Cron Analyzer
Cron Analyzer inspects a cron expression, estimates its frequency in human terms (e.g. "every 5 minutes", "hourly"), and warns about high-load schedules (e.g. running every minute).
Unlike the Cron Validator/Parser: it focuses on "how often & is it sensible". A heuristic estimate.
FAQ
Is my data sent to a server?
No. The entire analysis runs in your browser with JavaScript. Nothing is uploaded, logged, or stored on our servers — safe for sensitive data.
How is this analyzer different from a parser, validator, or viewer?
An analyzer produces an insight report — metrics, statistics, warnings, and recommendations — to help you judge the quality or characteristics of the input. A parser breaks it into structure, a validator gives a valid/invalid verdict, and a viewer just displays it. An analyzer focuses on "how good / what are its characteristics".
