Running multiple projects locally is painful.
localhost:3000, localhost:3001, localhost:8080... which one is which?
One port conflict and your whole setup breaks.
Portless by Vercel Labs fixes this cleanly.
Instead of port numbers, you get stable named URLs:
http://myapp.localhost:1355
http://api.myapp.localhost:1355
http://docs.myapp.localhost:1355
What it solves:
• Port conflicts across projects
• Cookie and storage bleeding between apps on different ports
• "Wait, which tab is which?" confusion in monorepos
• Git worktrees: each branch gets its own subdomain automatically
Works with Next.js, Vite, Express, Nuxt, React Router, Angular, Expo.
There's also an AI angle.
Coding agents were hardcoding ports and getting them wrong. Named URLs mean your agent always knows exactly where to go.
