Platformatic's Watt 3.18.0 integrates Next.js 16's explicit 'use cache' directive, enabling component-level caching in production via a new Redis/Valkey adapter. This solves critical self-hosting challenges like cache inconsistencies in scaled deployments, delivering Vercel-like performance without platform lock-in. Developers now have zero-config tools for fine-grained control and resource efficiency at scale.
