About This Launch
Cron Kit is a free set of browser-based cron expression tools. Explain schedules in plain English, validate across dialects, generate from text, and convert for Quartz, AWS EventBridge, Kubernetes, GitHub Actions, systemd, and more. Everything runs locally in your browser. No signup. Part of the TinyToolkit network of privacy-first format tools.
Why I Built This
Every time I needed to double-check a cron expression I ended up pasting it into some random site that wanted an account or shipped my schedule to a server. Cron Kit does the whole job locally in the browser: explain, validate, generate, and convert between dialects, with no upload and no signup.
