Custom Web App Development

We build web apps that run in the browser: the booking system, calculator, learning platform or dashboard your work depends on, from the first sketch to the live app and the login behind it.

Overview

Custom web app development for the tool your work depends on

A web app is software people use in the browser: a booking system, a price calculator, a learning platform, a dashboard over your data. Nothing to install, it works on any device, and when you change it, everyone has the change at once.

We build it from the first sketch to the live app: the screens, the back-end, the database and the login behind it. You get something to click through early and a say in every release.

Book a call

  • Forms, tables and dashboards that follow how the work is really done, with clear states for loading, empty lists and errors.

  • The back-end, database and API that hold your rules, with accounts and permissions wherever people log in.

  • The same app on desktop, tablet and phone, and installable to the home screen when that helps.

Why Softclaire

We build web apps that stay fast and stay easy to change.

Plenty of web apps work on launch day and become hard to touch six months later. We write ours so the second year is as easy as the first.

Tell us about your app

  • Fast where people work

    Screens open quickly on an average laptop and a mid-range phone. We measure it and treat a slow page as a bug.

  • Code the next developer can read

    Typed code, tests on the rules that matter and short notes on how the parts fit together.

  • Releases you can follow

    A working build every two weeks on a test address. You use it before anyone else does.

  • Yours from day one

    Source code, designs and accounts are in your name.

What we build

Web apps we build most often

Each one is built around your own rules, but these are the shapes we see again and again.

  • Dashboards and reporting tools

    Your data from several sources in one view, with filters and exports for the people who decide.

  • Booking and scheduling

    Requests, availability, confirmations and reminders for services, classes or appointments.

  • Learning and training platforms

    Courses, lessons, progress and certificates, with separate roles for teachers and learners.

  • Calculators and quote tools

    A tool that turns a customer’s choices into a price, a quote or an order.

  • Apps connected to other systems

    Data pulled from your accounting, CRM or stock tools, and changes sent back.

  • Forms, approvals and documents

    Multi-step forms, checks and generated documents that replace paper and e-mail threads.

Process

How a web app project runs

Short cycles, with an app you can click through from the first weeks.

  1. Workshop and scope

    We go through the job the app has to do, who uses it and what a first useful version contains.

  2. Design the screens

    Flows and screens in Figma, reviewed with you and with a few of the people who will use the app.

  3. Build in two-week sprints

    A working build on a test address at the end of every sprint. You change priorities as you learn.

  4. Launch and improve

    We deploy it, set up monitoring and stay close for the first weeks, fixing what real use shows.

Testimonials

What our clients say

Reviews from founders and teams we have built products with, also published on Clutch and TechBehemoths.

  • TechBehemoths

    Softclaire is development company unlike (many) others. Friendly and flexible, good with deadlines and trustworthy. Experts in multiple fields. We are very happy to work with them as development partner. Very much recommended!

    Arno Bakker Co-owner at Mediascape
  • TechBehemoths

    We have been working with Softclaire for almost 2 years now, on our main product - an online gaming website, play-games.com. Being in the web games niche, things change fast so we need to adapt on the go - and we can trust them with this. They are easy to work with, proactive, and manage work flow very well. We value their transparency and their perseverance in every task they undertake.

    Stefan Naghi Co-founder at FIRST PIXEL SRL
  • TechBehemoths

    We approached Softclaire with nothing more than an idea and a few initial mockups for our SaaS product. Their team stepped in guiding us through strategic planning, development and devops. We are still working with them for ongoing maintenance and feature updates. If you're looking for a reliable, long-term technical partner, I highly recommend them.

    Alexandru Mihalache
  • Clutch

    Within 6 months of our app launch we have gained 750 users. We have had a huge boost in traffic on the platform since launch and have multiple 5 star ratings on the App Store. We have also had comments from other software developers commenting on how brilliant the app is structured.

    Nassouh Kabbani CFO at Pocketask Inc.
  • Clutch

    The team delivered everything on time and provided a mind map to showcase the progress. Overall, they were very flexible and committed to meeting expectations.

    Mihai Brebu Director at Puapi
  • TechBehemoths

    We had an idea for a tech startup in the medical niche, but we lacked the expertise to design and develop a product of this scale. Thankfully we found an amazing team that guided us through the process every step of the way.

    Aron Dumitrache Medtech Innovator
  • TechBehemoths

    A few months ago, I contacted them for a custom Perfex CRM module and the e-Invoice module. Their work is of exceptional quality, and I am extremely satisfied with both the quality and the budget. I highly recommend Softclaire to all businesses and investors!

    Mirela Marin
  • TechBehemoths

    Softclaire created a beautiful, functional website for us, exactly as we instructed.

Frequently asked questions

Contact us
How much does it cost to build a custom web app?
It depends on how many screens and user types there are, how complex the rules are and what the app connects to. A single-purpose tool is a small project, an app with several roles and integrations is a large one. After a short workshop we give you a fixed price per phase.
How long does it take to build a web app?
A focused first version can take from a few weeks to a few months. We agree the timeline with the scope and show you a working build every two weeks, so you see the progress for yourself.
What is the difference between a web app and a website?
A website mostly shows information. A web app lets people do something: log in, enter data, get a result. If you need a site that presents your company, see presentation website.
Does a web app work on phones?
Yes. It adapts to any screen and can be added to the home screen like an app. If you need to be in the App Store and Google Play, see mobile app development.
Can the app connect to our existing systems?
Usually, through their APIs or by importing and exporting files. We check what your systems offer before we plan around them, and build each connection so it can be changed later.
Can the app grow with the number of users?
Yes. We pick hosting and a database that scale, and we test the slow parts before launch. Moving from a hundred users to many thousands is a planned step, not a rewrite.
Who owns the code?
You do. The source code, the designs and the hosting accounts are in your name, and we can sign an NDA before we start.
