it's basically unlimited, that's the idea of serverless. however, you will hit the limits of whatever plan you're on: https://vercel.com/docs/limits/overview so then it comes down to billing.

might be worth considering rate limiting your next.js routes with something like https://github.com/upstash/ratelimit if you want to use Redis or https://www.npmjs.com/package/@arcjet/next which I'm building (doesn't require Redis).

also worth looking at https://vercel.com/docs/accounts/spend-management which is relatively new and lets you get alerts and shut down your projects if you hit certain spend limits

@davidmytton Thanks man! So, if my application gets around five hundred simultaneos access, the vercel host wil not increase the time to provide the static contents?

it should handle it fine - they'll all be served in parallel

especially if it's static content

@davidmytton Do u know any link that specifies the ram memory on vercel free plan?

Are u telling me that my FREE VERCEL HOSTED WEBSITE built on next will handle fine to 30 thousands concurrency access?

yeh that's what the limit docs says

Are you doing anything beyond static content?

Like db access ?

No, only static content

Then you’re fine.

Thans man!
