Vercel Blob usage is measured on the following:
- Amount of Blob Storage used: We calculate a monthly average as GB-month.
- Number of Simple Operations: A simple operation occurs when a blob is accessed by its URL and it’s a cache MISS or when the HEAD method is called
- Number of Advanced Operations: An advanced operation is when any of following methods are called: put, copy, list. Be aware that multipart uploads are counted as multiple advanced operations: one when starting the upload, one for each part, and one for completing the upload.
- Amount of Blob Data Transfer used: Data is transferred whenever a blob is accessed by its URL, such as during file downloads, image views in a browser, or when your website serves blob content as assets.
- Delete operations are free.
The size of the operation does not affect whether it’s simple, however it can count as multiple operations in the case of a multi-part upload. A get is a single simple op, while a list is a single advanced operation
Vercel Blob is coming out of beta VERY soon, to the point that it is unlikely you will hit any of the beta limits between now and then.
The pricing structure will stay the same as it right now, except overages above your tier will be charged per additional operation. We will support spend management to prevent any unexpected overages. I can’t leak the exact numbers but this will be finalized in the very near future.
