Elastic build machines, released in beta on March 24, are now generally available for all Pro and Enterprise customers, and are now the default for all new Pro teams.

Rather than a one-size-fits-all approach, Vercel evaluates each project individually and assigns the right machine for its actual needs balancing speed and cost. Over 400 teams and 6,000 projects have enabled Elastic as their default build machine.

During the beta, approximately 80% of projects have reduced their costs by switching to smaller build machine while maintaining their build speeds. The remaining 20% of projects have been auto upgraded to machines with more CPUs and memory improving their build speed.

Enable elastic builds in your team settings or project settings, or read the builds documentation.
