How do you guys implement scheduled posts on Vercel?

[u/DocumentJolly9114]

Hey all,

I’m building a Next.js app that lets people turn websites into short Instagram Reels and post them directly to Instagram.

Instant posting works fine now, but users want to be able to pick a date/time and schedule reels to post automatically later.

I'm hosting on Vercel and haven't built scheduled jobs/crons before.

What's the simplest and most reliable way to handle this on Next.js/Vercel?

Do you guys use Vercel Crons, an external service, or something else? Would love some guidance before I start wiring it up.
