What Is Web App Development?
Web app development is the process of designing and building interactive software that users access through a web browser.
Unlike a traditional informational website, a web application allows users to perform actions and interact with business systems.
For example, a website might provide information about a company, while a web application could allow users to:
- Create an account
- Submit information
- Make payments
- Manage orders
- Track services
- Upload documents
- Communicate with other users
- View personalized dashboards
- Manage business operations
A web application can therefore function as a complete digital product rather than simply an online presence.
Web Application vs Website
The two terms are sometimes confused, but their purpose is different.
Website | Web Application |
Primarily provides information | Provides interactive functionality |
Often public-facing | Can be public or private |
Content-focused | Workflow and functionality-focused |
Usually simpler user interaction | More complex user interaction |
Example: company website | Example: CRM or SaaS platform |
Many modern businesses use both. A company website can attract visitors, while a web application provides the actual product or service experience.
Types of Web Applications We Develop
The right type of web application depends on your business model.
Customer-Facing Applications
These applications allow customers to access services, manage accounts, place orders, make payments, and communicate with businesses.
Internal Business Applications
Internal applications can automate company workflows and provide employees with centralized tools.
SaaS Platforms
SaaS products provide software through the internet, generally using subscription or usage-based models.
Marketplace Platforms
