JustRun vs Vercel Cron Jobs

Cron jobs that aren't tied to your deployment.

Vercel Cron Jobs run on vercel.json config — they're tightly coupled to your Vercel project and deployment. JustRun is deployment-agnostic: configure cron jobs independently, call any URL, get AI diagnostics and proper alerting.
