Data Cache is moving to Runtime Cache

Vercel is moving Data Cache out of beta and into Runtime Cache. Next.js fetch caching and unstable_cache switch over on every version without code changes, but previously unbilled reads and writes become billable after migration.

Rates start at $0.40 per million read units and $4.00 per million write units, varying by region. Each operation rounds up to an 8 KB unit. Hobby includes 1 million read units and 200,000 write units monthly across all projects. Pro usage draws from the $20 monthly infrastructure credit; Enterprise pricing comes through the account team.

Pro gets separate storage per project and environment, with 8x the space of the old team-wide pool. Enterprise projects get 10x their previous storage.

Teams created on or after October 30, 2026 use Runtime Cache by default. Existing Hobby teams are scheduled to migrate November 29, 2026; Pro teams will receive migration and billing dates, and Enterprise teams will hear from their account teams. Existing Hobby and Pro teams can opt in early through CDN settings, with pricing taking effect immediately. Check Data Cache usage in Observability before migrating.
