Incremental Static Regeneration usage and pricing

Vercel offers several methods for caching data within Vercel’s managed infrastructure. Incremental Static Regeneration (ISR) caches your data at the edge and persists it to durable storage – data reads and writes from durable storage will incur costs.

ISR Reads and Writes are priced regionally based on the location of the request. See the regional pricing documentation for more information.

The table below shows the metrics for the ISR section of the Usage dashboard.

To view information on managing each resource, select the resource link in the Metric column. To jump straight to guidance on optimization, select the corresponding resource link in the Optimize column. The cost for each metric is based on the request location, see the pricing section and choose the region from the dropdown for specific information.

See the manage and optimize ISR usage section for more information on how to optimize your usage.

There is no limit on storage for ISR, all the data you write remains cached for the duration you specify. Only you or your team can invalidate this cache—unless it goes unaccessed for 31 days.
