Faster Deploys for ISR Pages on Vercel

Vercel's August 4, 2026 change reduced deployment work for sites with many prerendered pages. Each page carries routing metadata, and large amounts of that metadata previously required a separate upload. Vercel changed the process so it ships in one upload, reporting deployments up to 33% faster. The announcement says the improvement applies automatically to Incremental Static Regeneration and other prerendered pages. It shortens the process of publishing a deployment; the reported percentage measures deployment time.

“Deploys are now up to 33% faster for apps using Incremental Static Regeneration (ISR).”

“The more prerendered pages you have, the more you're likely to save.”

“Previously, when that metadata grew too large, it split into a separate upload, adding work to every deploy.”

“This applies automatically to every deploy, with no configuration needed.”
