Web applications are online tools that allow you to perform tasks through a web browser.
Unlike a basic website that mainly displays information, a web application lets you log in, enter data, upload files, make payments, communicate with other users, or receive personalised results.
You probably use several web applications every day without thinking about it. Gmail, Glarify, Canva, Google Docs, online banking platforms, social media sites, and ecommerce stores are all examples of web applications.
This article looks at common examples of web applications, how they work, and what you need to build and host one.
What is a web application?
A web application is software that runs on a web server and is accessed through a browser such as Chrome, Firefox, Safari, or Microsoft Edge.
You usually do not need to install the full application on your computer. You visit a web address, sign in, and use the application online.
For example, when you open Gmail, your messages are stored and processed on Google’s servers. Your browser displays the interface and allows you to read, send, delete, and organise emails.
A web application may allow users to:
Create an account
Log in securely
Enter or edit information
Upload files
Make payments
Search a database
Send messages
Book appointments
View personalised content
Generate reports
Collaborate with other users
The exact features depend on the purpose of the application.
Website vs web application
A website and a web application can look similar, but they serve different purposes.
Feature | Website | Web application |
|---|---|---|
Main purpose | Share information | Help users complete tasks |
User interaction | Usually limited | Usually high |
User accounts | Sometimes | Common |
Personalised content | Limited | Common |
Data entry | Minimal | Frequent |
Examples | Company website, blog, news site | Gmail, Canva, online banking |
Hosting needs | Often simple | May require more server resources |
A small company website may show services, prices, contact details, and business hours.
A web application may allow the same company’s customers to create accounts, request services, track orders, download invoices, and make payments.
Some platforms combine both.
For example, an ecommerce site has informational pages, product descriptions, and blog posts. It also functions as a web application because customers can create accounts, add products to a cart, and complete payments.
25 examples of web applications

Types of web applications
Web applications can also be grouped according to how they function.
1) Static web applications
A static web application displays content that changes very little.
It is built using files such as HTML, CSS, and JavaScript.
Static applications are fast and relatively easy to host, but they offer fewer interactive features unless connected to external services.
Examples include:
Portfolios
Product showcases
Simple campaign pages
Documentation websites
Basic business websites
2) Dynamic web applications
A dynamic web application generates content based on user requests, stored data, or account information.
It usually connects to a database.
Examples include:
Social media platforms
News websites
Customer portals
Ecommerce stores
Online banking platforms
The content may change for each user.
3) Single-page applications
A single-page application loads one main page and updates content without reloading the entire browser window.
This can make the application feel faster and more similar to installed software.
Examples include parts of Gmail, Trello, Google Maps, and many modern dashboards.
Single-page applications are often built using frameworks such as React, Vue, or Angular.
4) Progressive web applications
A progressive web application, or PWA, is a web application designed to behave more like a mobile application.
Depending on the device and browser, it may support:
Installation on the home screen
Push notifications
Offline access
Background updates
Fast loading
A PWA can be useful when a business wants an application-like experience without building separate Android and iOS applications.
5) Ecommerce web applications
Ecommerce web applications allow businesses to sell products or services online.
They typically include:
Product pages
Shopping carts
Checkout
Online payments
Customer accounts
Order tracking
Inventory management
Examples include Amazon, Shopify stores, Jumia, and WooCommerce websites.
6) Portal web applications
A portal gives users access to information and services through a central dashboard.
Different users may see different content based on their roles.
Examples include:
Student portals
Employee portals
Customer portals
Supplier portals
Government service portals
Hosting client areas
7) Content management systems
A content management system allows users to create and manage website content without editing code directly.
WordPress is the most widely recognised example.
Other content management systems include Joomla, Drupal, Ghost, and TYPO3.
8) Online marketplaces
An online marketplace connects different groups of users.
For example, a marketplace may connect buyers with sellers, passengers with drivers, or property owners with guests.
Examples include:
Airbnb
Uber
Amazon Marketplace
Fiverr
Upwork
Jiji
Etsy
The platform usually earns money through commissions, subscriptions, listing fees, or advertising.
How does a web application work?
Most web applications contain several connected parts.
The frontend
The frontend is the part users see and interact with in the browser.
It includes:
Pages
Buttons
Forms
Menus
Images
Dashboards
Notifications
Frontend technologies commonly include HTML, CSS, and JavaScript.
Frameworks such as React, Vue, and Angular may also be used.
The backend
The backend handles the application’s logic behind the scenes.
It may process logins, calculate results, send emails, retrieve records, manage payments, or apply user permissions.
Backend applications can be built using technologies such as:
PHP
Python
Node.js
Java
Ruby
.NET
The database
The database stores information used by the application.
This may include:
User accounts
Products
Orders
Messages
Appointments
Payments
Settings
Reports
Common databases include MySQL, PostgreSQL, MariaDB, MongoDB, and Microsoft SQL Server.
The server
The server runs the application and responds when users make requests.
For example, when a customer logs in, the server checks the submitted details, confirms the account, retrieves the correct information, and sends the dashboard back to the browser.
The quality of the server affects the application’s speed, reliability, and ability to handle many users.
Application programming interfaces
An application programming interface, commonly called an API, allows different systems to communicate.
A web application may use an API to:
Process payments
Send SMS messages
Display maps
Verify users
Send emails
Retrieve exchange rates
Connect to social media platforms
For example, an ecommerce application may connect to an M-Pesa API to accept payments.
What do you need to build a web application?
The exact requirements depend on the application’s complexity.
A basic web application may require:
A frontend
A backend
A database
An SSL certificate
User authentication
Regular backups
A larger application may also require:
Cloud storage
Load balancing
Monitoring
Automated deployment
Database replication
Security testing
Content delivery networks
Separate development and production environments
Planning these requirements early can reduce performance and security problems later.
Shared hosting vs VPS hosting for web applications
Some small web applications can run on shared hosting.
For example, shared hosting may be enough for:
A simple WordPress membership site
A small WooCommerce store
A basic appointment system
A small customer portal
A lightweight PHP application
Shared hosting is easier to manage and usually costs less.
However, a virtual private server may be more suitable when the application:
Receives high traffic
Runs background tasks
Requires custom server software
Uses Node.js or specialised frameworks
Needs more memory or processing power
Stores large amounts of data
Requires greater server control
Handles many simultaneous users
A VPS gives you dedicated server resources and more control over the hosting environment.
How to choose hosting for a web application
Consider the following factors before selecting a hosting plan.
Expected traffic
Estimate how many people may use the application at the same time.
An application with 100 monthly users has different server requirements from one serving thousands of users every day.
Technology requirements
Check which programming languages, databases, frameworks, and server tools the application requires.
Not every hosting plan supports every technology.
Storage
Consider how much space is required for databases, images, videos, documents, backups, and user uploads.
Performance
Slow applications frustrate users and may reduce conversions.
Choose hosting with enough memory, processing power, and storage performance for the application.
Security
Applications that handle personal data, passwords, payments, or business records need strong security controls.
At minimum, use an SSL certificate, secure passwords, software updates, backups, and restricted user permissions.
Scalability
Your hosting environment should be able to grow as the number of users, transactions, and stored records increases.
A small application may begin on shared hosting and later move to a VPS.
Technical support
Reliable support is important when an application becomes unavailable or develops a server-related problem.
Choose a hosting provider that can help you resolve hosting, domain, SSL, and server issues.
Examples of web applications a small business can build
You do not need to create the next Facebook or Amazon.
A focused web application can solve one specific business problem.
A small business could build:
A salon appointment system
A school fee portal
A rental property management platform
A customer quotation tool
An online ordering system
A delivery tracking portal
A membership website
An employee leave management system
A restaurant reservation platform
A church membership system
A loan repayment calculator
A local job portal
A supplier management platform
A customer support portal
A course and examination system
The best applications often begin with a clear problem faced by a specific group of users.
Benefits of web applications
Web applications offer several advantages to businesses and users.
Accessible from different devices
Users can access the application through a browser on a computer, tablet, or phone.
No full desktop installation
Most web applications do not require users to install large software packages.
Easier updates
Developers can update the application on the server. Users receive the latest version the next time they open it.
Centralised information
Data can be stored in one central system rather than spread across different devices or spreadsheets.
Collaboration
Several users can work on the same records, tasks, documents, or projects.
Automation
A web application can automate repetitive processes such as sending invoices, confirming bookings, calculating totals, or generating reports.
Business growth
A web application can help a business serve customers beyond its physical location and operate at any time of day.
Challenges of web applications
Web applications also come with responsibilities.
Security threats
Applications can be targeted through weak passwords, outdated software, insecure code, or poorly protected databases.
Internet dependence
Most web applications require a stable internet connection.
Development costs
Custom applications may require design, development, testing, hosting, maintenance, and ongoing improvements.
Performance problems
Poor code, weak hosting, large files, or inefficient databases can make an application slow.
Maintenance
A web application is rarely complete after launch. It needs software updates, backups, security checks, monitoring, and feature improvements.
