Build cache size limit on Vercel increased to 5 GB

Vercel announced an increase to the build cache size limit on all build machines, raising it from previous tiers to a uniform 5 GB. This adjustment allows projects to retain larger sets of installed dependencies and framework files for reuse across deployments. The change is intended to reduce both installation and build times by preserving more cached data between builds. No manual configuration is required, and the update applies automatically across all build machine types.

Previously, caches were discarded if they exceeded specific thresholds depending on the build machine tier: 1.5 GB on Basic and Standard, 3 GB on Enhanced, or 4.75 GB on Turbo. Exceeding these limits would leave subsequent builds without cached data, forcing a full reinstallation of dependencies. The new 5 GB limit removes these tiered restrictions, providing a consistent cache capacity for all projects. This update applies universally across Vercel’s infrastructure without additional charges.

The adjustment impacts projects that rely on large dependency sets or multiple framework files, as these can now be cached more effectively. Vercel’s build machines handle the installation and compilation of project files before deployment, and the expanded cache size helps streamline this process. Projects previously constrained by cache limits will benefit from faster rebuilds and reduced resource usage during deployments. The change is part of ongoing efforts to optimize build performance across Vercel’s platform.

Vercel emphasized that the update is available at no extra cost and requires no action from users to take effect. The company highlighted that the increased cache size will particularly benefit projects with extensive dependency trees or those using multiple frameworks. This move aligns with Vercel’s commitment to improving developer experience by reducing build times and simplifying deployment workflows. The change is effective immediately across all build machine types.
