Limits and Pricing for Vercel Flags

Last updated February 11, 2026

Vercel Flags is priced at $30 per 1 million flag requests ($0.00003 per event).

A flag request is any request to your application that reads the underlying flags configuration. A single request evaluating multiple feature flags of the same source project still counts as one flag request.

For example, if a page request evaluates 10 different feature flags, that counts as 1 flag request.

If a project reads feature flags from multiple sources, each source is counted separately.

On the Hobby plan, flag request collection pauses once you reach 10,000 requests in a billing cycle.

Both active and archived flags count toward the total flag limit. Delete flags to free up space.
