Web application development

Tinloof is a web app development agency that designs and builds user-friendly, fast, and reliable digital solutions.

Web apps built by Tinloof

What is a web application?

A web application is a website that provides a set of features to its users.

Unlike marketing websites that are often accessible publicly, web applications usually restrict access to their features via a login, and provide a dashboard for their users to manage their profile, preferences or billing information.

Recurring features we build

Billing / Payment

Web applications usually charge users for the features they provide, and we believe that a successful billing experience should follow commonly used payment models to avoid confusing users.

Billing, which is an essential component in paid web applications, is also very hard to get right if you try to implement it from scratch.

That's why we use Stripe, the most robust and widely used payment platform, to implement Billing for any web application we build. If you ever have paid for anything online, there's a good chance you used Stripe yourself.

It supports a wide range of payment models that are carefully explained in their documentation. It also offers a built-in checkout screen, supports having a completely custom checkout flow, and has a dashboard to track and manage customers' payments.

Authentication and user management

Most web applications provide features tailored to users that are protected by a signup/login flow. This could be through an email and password, magic link, or Single Sign-On (SSO).

Our tool of choice to easily implement any authentication and user management flow is Supabase.

We use Supabase because it allows us to deliver user-friendly and secure authentication flows. We can do that because Supabase provides built-in APIs and JavaScript libraries to implement and fully customize any protected backend.

It also deploys a Postgres database by default in the cloud that is protected against DDOS attacks, so we can just focus on implementing features.

Dashboards / Data Visualisation

Dashboards are a great way to visualize data and we love the exercise of translating large datasets into appealing charts or tables that are useful for users and easy to understand.

Performance is a key component when it comes to delivering user-friendly dashboards, so we use React frameworks such as Remix or Next.js to render live data before it even reaches the browser.

We also use TypeScript to share type definitions between the backend and the frontend and make data predictable enough to avoid bugs.

Content management

Having the right textual and media (images, videos) content is an essential part of the user experience a web application provides to its users.

We strongly believe that it should be decoupled from the code of the web application itself and that it should be easily manageable without developers' involvement.

That's why we use Sanity, the best Headless CMS according to G2's 2022 ranking, to make it possible to easily manage the content of web applications.

Another advantage of using a Headless CMS to manage content is that it becomes very easy to translate the content if the web application is available in multiple languages. You can read more about how we handle localization with Sanity in this article.

Search engines

We use Algolia to power any web application with a search engine.

Algolia's search solutions make it possible to index any source of data (e.g. Database, CMS) and make it instantly searchable.

It provides great APIs and JavaScript libraries to achieve that in any setup, regardless of the web application we're building.

Happy clients

Tinloof helped us build a new version of our website that is completely customisable from a Headless CMS called Sanity.
This saved us months of engineering work and helped us rank number 1 on Google for certain terms.
We were also able to benefit from their web development expertise to launch a referral program and a live chat.
They are true experts in their field and more importantly kind human beings that are great to work with.

Had the pleasure of collaborating with the agency for building a frontend for our backend offering.
Things went smoothly, there were no delays in feature deliveries and in terms of communication, my feeling is that we were always on the same page. I can only higlhly recommend Tinloof!

About Tinloof

We're a web application development company that consists of 10 experienced web developers and designers that are proud of the work they deliver.

We are not only "executors". While we do excel at this, we also integrate with your team, suggest improvements and ideas when we see fit, consult whenever needed, and ensure we are available until the successful launch and beyond.

Although we love the libraries and programming languages we use, we are not tied to them. For us, they are just tools, and our goal is to find the right ones for the web application we're building.

We care about the look and feel, the user experience, the speed, and the reliability of the web apps we build. This is reflected in the way we work and the decisions we make in collaboration with you.

How Tinloof builds web applications


We're research-oriented, so from the moment you reach out to us, we start collecting all the information we need to craft a plan to build your web application.

This is why our proposals always include a rough plan of the architecture of your web application, the tech stack we'll be using, and most importantly, the various milestones of the project.

Roadmap and task management

From day 1 we set up a Notion page with a roadmap that includes the main migration milestones and a board to track our day-to-day tasks.

If you already have a team, we would usually work as an embedded part of the team and add tasks on your preferred task management tool (e.g. Jira, Notion, Linear).


We use Slack to make communication as fast and as easy as possible.


We work in iterations and ask for feedback as soon as we make progress. These small feedback iterations make it easy for everyone to be aligned and progress faster.

Frequently asked questions

Why should I work with a web application development company?

Building web applications is a challenge, but by working with a web app development agency that has a solid experience with a full cycle of designing and implementing a web application, you'll have a much better chance of reaching your goals. You will also be able to save considerable time and resources, especially if they act as a true embedded and transparent partner.

As a specialist ecommerce app development agency, we are also experienced in helping ecommerce businesses with ecommerce and Shopify app development.

How much does web application development cost?

That will depend on the scope of your requirements and how they are.

We're usually able to provide a fixed price and time estimate if we're able to work with you to formulate all the requirements of your web application.

However, this is not always the case. In these instances, we would either offer a research phase to nail the requirements or an ongoing agreement with daily rate.

Why does my business need a custom web application?

Successful web applications provide relief to their users by helping them to smoothly solve a specific problem.

Custom web applications achieve that result better than any application generated by a no-code tool, because their speed is unbeatable and they are built with their users' experience in mind.

Do you develop mobile apps as well as web apps?

Yes, we also design and develop mobile apps. We ship native apps that run on iOS and Android, but also progressive web apps (PWA) that run on any device.

You can find out more details on our mobile app development page.
