I'm looking into how to do cron jobs well for NextJS apps deployed on Vercel or Netlify.    There are very popular ways of handling this:  - Ruby on Rails has Sidekiq  - .NET has Hangfire  - Celery for Django (Thanks Sergio)    Do you know of something similar in the NextJS / Node world?    I'm considering SaaS and run-it-yourself open source solutions.    If I can't find what I'm looking for, I'm considering building something.    Thanks.
