Vercel Cron Jobs

Edit this Post Opens in new tab

Vercel released Cron Jobs Opens in new tab recently! That is pretty cool. It's a feature a lot of people longed for because something like this was not available yet when using serverless environment like Vercel.

Now you can automate repetetive tasks without having a backend. To get started with Cron Jobs in Vercel you have to create a vercel.json file. Here are some example Cron Jobs:

  "crons": [
      "path": "/api/backup",
      "schedule": "0 0 * * *"
      "path": "/api/weekly-mail",
      "schedule": "0 0 * * 1"

Cron Jobs use a specific syntax to determine the time when the job should be executed. The schedule string consists of five fields separated by spaces. They stand for minute, hour, day, month and day of the week.

So the first job in the example above will be executed every day at midnight. While the second job will be executed every Monday at midnight.

With the Hobby plan you get two Cron Jobs for free which each can be triggered once per day, while the Pro plan offers 40 Cron Jobs in total with unlimited usage per day.
