What is a custom web app?

A custom web app is software that runs in the browser and is built for one business's exact workflow, instead of an off-the-shelf tool you have to work around. It usually has user accounts, a database, an admin area and connections to other services such as payments or email. Customers, staff or partners use it from any device without installing anything.

What we build

Web apps we build

Dashboards and admin panels

One place to see your numbers, manage orders, users and content, with charts and exports instead of spreadsheets.

Client and partner portals

Secure areas where customers log in to see projects, invoices, documents or support tickets.

SaaS products and MVPs

Subscription software with sign-up, plans, payments and onboarding — from a first version you can test with real users to a full product.

Booking and scheduling systems

Online booking with availability, payments, reminders and a calendar for your team.

Internal business tools

Replace spreadsheets and manual steps with a tool that fits how your team actually works: approvals, inventory, quotes, job tracking.

Marketplaces and directories

Listings, search and filters, profiles, messaging and payments between buyers and sellers.

How it works

How we build your web app

Every project starts with understanding the job the app has to do: who uses it, what they need to get done, and which steps or systems it replaces. We turn that into a short plan with screens, features and a fixed price, so you know exactly what you are getting before any code is written.

We then design the main screens and build the app in small steps. Every week you can open a private preview link, click through what is finished and ask for changes early, when they are quick and cheap to make — not at the end.

We build on proven open-source tools, mostly Laravel on the backend and React or Vue on the frontend, so any good developer can carry on the work later. When the app is tested and live, you receive the full source code, the database and every account in your name.

  • Laravel
  • PHP
  • React
  • Next.js
  • Vue
  • Node.js
  • Python
  • MySQL
  • PostgreSQL
  • Stripe
  • REST APIs

Process

From first message to launch

  1. 1

    Share your idea

    Tell us what the app should do and who will use it. Within one business day you get questions, a plan and a fixed-price quote.

  2. 2

    Design and build

    We design the key screens first, then build in small steps you can try every week on a private preview link.

  3. 3

    Launch and hand over

    We test, deploy and hand over the code and accounts. Bug fixes after launch are free, and we can keep adding features whenever you need.

Pricing

How much does a custom web app cost?

The cost of a web app depends on how many screens and user roles it has, how complex its rules are (for example pricing, approvals or scheduling), which systems it connects to, and whether you need payments, reports or a mobile version. A focused first version with the essential features costs far less than a full product, and is often the smartest start: launch, learn from real users, then add more. Most web apps take 3 to 8 weeks. Send us your idea and you get a fixed price, free, within one business day.

FAQ

Custom Web App Development questions

How long does it take to build a web app?

Most web apps take 3 to 8 weeks, depending on the number of features and integrations. Your quote includes a timeline with dates for each stage.

Can you build a first version (MVP) quickly?

Yes. We help you choose the few features that prove your idea, launch those first, and add more once real users have tried it.

Which technology do you use?

Mostly Laravel (PHP) for the backend and React, Next.js or Vue for the frontend, with MySQL or PostgreSQL. These are popular, well-supported tools, so you are never locked in to us.

Can you take over a web app another developer started?

Yes. We review the existing code first, tell you honestly what state it is in, then fix, finish or extend it.

Will the app work on phones?

Yes. Every web app we build is responsive, so it works in mobile browsers. If you also need an app in the App Store or Google Play, we can build that too.

Do I own the code?

Yes. Once the project is paid, you get the full source code, the database and every account in your name.
