Limits and Pricing for Vercel Flags
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.
| Hobby | Pro | Enterprise | |
|---|---|---|---|
| Maximum flag requests per month | 10,000 | None | None |
| Additional flag requests | - | $30 per 1 million requests (prorated) | $30 per 1 million requests (prorated) |
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.
