If you're splitting a monolith across teams or composing multiple Next.js, SvelteKit, or Vite apps under one domain, this handles the routing plumbing on Vercel's edge. You define path patterns in microfrontends.json, set asset prefixes to avoid collisions, and each team deploys independently while the whole thing feels like one app to users. The CLI handles group creation and local dev proxy setup. What's nice is the reference docs are organized by topic, so you grep for what you need instead of wading through everything. Works well for incremental migrations or when you need feature flag controlled routing between projects.
