Web app development

Web app development for startups and businesses

When a website isn't enough, PlusTechnology's web app development team builds apps for your customers or your staff, starting with a focused first version you can launch quickly and grow from there.

In short

PlusTechnology is a web app development studio that builds SaaS MVPs, client portals, dashboards and booking systems with React, Next.js and Laravel. A focused MVP typically takes 6–10 weeks and costs about $5,000–$20,000; more complex web app development takes longer and costs more.

Most web app development projects fail by building too much too early. We start by finding the one workflow your users actually need, build that well, and launch it. Then we improve based on real usage.

Our web app development uses proven building blocks for authentication, payments and email, such as Stripe and Supabase, instead of reinventing them, which keeps your first version affordable and secure.

  • Product scoping workshop
  • Clickable prototype before build
  • Authentication and user roles

  • Milestone demos every 1–2 weeks

Who this is for

  • Companies adding AI features to their product
