Possible disadvantages

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing NextUp Walk-in and Nullstack.

How would you describe the primary audience of your product?

NextUp Walk-in's answer

Small walk-in service businesses in the United States, usually 1–10 staff: barbershops, hair and nail salons, tattoo and piercing studios, phone repair shops, pet groomers, auto service counters, and restaurants with a waitlist.

What's the story behind your product?

NextUp Walk-in's answer

Walk-in shops lose customers to the wait they can see. A full waiting room tells someone at the door to come back later, and most don't. I built NextUp so they can hold a spot from wherever they are, watch the line move on their phone, and come back when it's nearly their turn. It's made for barbershops, salons, tattoo studios, repair shops, and other places where the line is the business. NextUp LLC is based in Jacksonville, North Carolina. — Nicholas Chadwick, founder

Which are the primary technologies used for building your product?

NextUp Walk-in's answer

.NET (ASP.NET Core), Angular, PostgreSQL, SignalR for live updates, Stripe for payments, Twilio for text messages (texts coming soon), Capacitor for the Android app (iPhone and iPad coming soon), SwiftUI for the Apple TV app, and BrightScript for the Roku app.

What makes your product unique?

NextUp Walk-in's answer

It's built around the walk-in line first, not the appointment calendar. Customers join by QR code with no app and see a live wait, while a waiting-room TV shows who's being called. Text notifications are coming soon: customers will get a text when they're almost up. Text alerts switch on soon, once carrier verification finishes. Appointments run on the same line instead of in a separate system, and each customer can choose a specific team member or take whoever is free first.

Why should a person choose your product over its competitors?

NextUp Walk-in's answer

Simple, flat pricing for small shops: $29/month per location (Walk-in plan; texts coming soon), 3 team members included per location, then $10 a month (or $100 a year) each (Restaurant has no seat charge), and the TV display, door tablet, and staff screen all included. Many queue tools charge separately for texts or put displays and kiosks on higher plans, and full salon suites are often more than a walk-in shop needs. You can try a live demo line from your phone with no sign-up at nextupwalkin.com/demo.

  • I built a walk-in waitlist app for barbershops and salons
    Walk-in shops have a quiet problem: someone walks in, sees a full waiting room, and leaves. I built NextUp Walk-in so people can hold their place in line from their own phone instead. - Source: dev.to / 11 days ago
