Vercel Sandbox Adds Custom Images in Public Beta
Vercel launched a public beta for custom images in its Sandbox environment, allowing developers to use their own root filesystem from the Vercel Container Registry. Images boot from precompiled snapshots to maintain cold start performance. The feature enables custom OS, toolchains, and dependencies without separate compute or snapshots.

This bridges the gap between container flexibility and serverless speed, but the beta label means production reliability remains unproven.
