# IndieCrontab

> See what a cron expression means, its next five runs, and whether Cloudflare, GitHub Actions, Vercel, and AWS accept it.

IndieCrontab is a free, one-input web utility for indie makers at indiecrontab.com. It takes one text, for example */15 9-17 * * 1-5, and answers in about ten seconds. Every answer names its source next to it. No account, no card, no premium plan, no upgrade nag, no hidden paywall. Private lookup activity is never published, and nothing on the page counts anyone. Every page is static HTML, and each link below is that page as Markdown or plain text. Made by turushan, https://twitter.com/turushan.
