Elastic Build Machines Introduces Feature to Prevent Out-of-Memory (OOM) Builds

·2026.06.02 03:30

Key point

Vercel's **Elastic Build Machines** monitors memory usage during builds to automatically prevent out-of-memory (OOM) errors.

Details

Elastic Build Machines monitors the memory usage of the build process in real time and automatically adjusts specifications to prevent out-of-memory (OOM) failures.

Key features are as follows:

  • Does not force a downgrade to a smaller-spec machine even when a memory-intensive build occurs
  • Automatically upgrades to a higher-tier machine when a risk of out-of-memory is detected
  • If a build fails due to an OOM error, the next deployment automatically runs on a higher tier

The thresholds have been set conservatively to balance deployment reliability and cost. Also, Vercel only considers the memory usage that actually occurs during the build process, not the memory usage of its own infrastructure.
