NextUp Walk-in is a walk-in queue and virtual waitlist for barbershops, hair and nail salons, tattoo studios, pet groomers and other walk-in service shops. Customers scan a QR code and hold their place in line from their own phone, with a live wait time and no app to install.

Staff call people from one screen, a waiting-room TV shows who is next, and a door tablet lets walk-ins check themselves in. There is a free plan (one location, 50 check-ins a month); paid plans start at $29 a month per location, with a 14-day free trial. Built with .NET 10, Angular and PostgreSQL, with native Apple TV, Roku and Fire TV apps. Try the live demo: nextupwalkin.com/demo
