CronLabs

Most cron failures aren't logic bugs — they're environment mismatches. A script runs perfectly in your terminal, then silently dies in crontab because cron executes with a minimal environment: no PATH, no aliases, a different working directory. CronLabs exists to catch exactly that class of failure before deploy.

The product covers the full pre-deploy checklist: paste a cron expression and instantly see when it will actually run, point your script at a capture endpoint to inspect every header, body, and timing it sends, and compare your local environment against cron's to surface mismatches before they bite.

CronLabs is built end to end on Next.js and Tailwind CSS with Supabase powering auth and data, deployed on Vercel — webhook capture, request history, and a free tier with unlimited expression validations. I own the full lifecycle: product, engineering, marketing, and SEO. Where monitoring tools tell you a job failed in production, CronLabs is testing: it tells you before you ship.
