Frequently Asked Questions

Web application development typically uses a combination of languages, including HTML, CSS, JavaScript, GraphicQL for the frontend, and languages like Python, Ruby, PHP, Java, C#, Golang, Swift, Kotlin, Rust for the backend. Frameworks such as React, Angular, Vue.js, Svelte, TypeScript, or Django are also used to streamline the development process.

The cost of web application development can vary widely based on factors like complexity, features, and timeline. Generally, simple web apps that use custom PHP development services to be developed in standard timeframe can range from $1,000 to $5,000, while complex applications can cost anywhere from $20,000 to over $100,000.

Really depends on architecture and tech-stack in addition to complexity and features.

While AI technologies have made significant advancements and can automate certain tasks, the role of a skilled development team is still absolutely crucial for building successful, tailored web applications and ensuring their long-term success. We have onboarded a number of customers because of this very reason.

AI tools are supplements, not replacements. They can generate codes but do not bring business specific logic.

AI tools lack customization options for features and functionalities. A developer team works closely with you to build a tailor-made solution that aligns with your brand, vision, and specific goals.

Many applications require complex logic, integration with third-party services and infrastructure, special functionalities that AI tools may not be able to handle out of the box.

AI tools may assist with initial setups, but they often lack the in-depth flexibility needed to scale, optimize, and secure your application as it grows.

Building and launching a simple app or website is just the beginning. Continuous support, bug fixes, and optimizations are vital for ensuring your application meets users’ evolving needs.

Our teams bring a personalized, human-centered approach to ensure that the application is built to perfection, is scalable, secure, and truly aligns with your business objectives. You don't need to spend time juggling different technologies. You do what you are at best. Grow your business!

Mobile app development focuses on creating applications specifically for mobile devices, often requiring platform-specific coding (iOS or Android). Web app development involves creating applications that run in a web browser. These can be hosted on premises or on cloud based on your preference.

The key stages of web app development typically include discovery, planning, design, development, testing, and deployment. Each stage plays a crucial role in ensuring that the final product meets user needs and functions smoothly.

At Intelygic, we establish regular cadence meetings to ensure effective project management to avoid surprises.

The time required to develop a web application can vary widely based on its complexity, features, and design. A simple web app may take couple of weeks, while complex applications can take several months or longer to complete.

We set milestones during planning phase and follow that timeline to ensure project is delivered within time and cost.

Ensuring the security of your web application is a multi-faceted process that involves a combination of development process, infrastructure security, regular testing, and proactive monitoring.

A web application is designed to allows users to perform multiple tasks online, interact dynamically with data, and engage with the system for complex functionalities. Examples will be social media platforms, online banking, email clients like g-mail and outlook, e-commerce platforms.

In contrast, websites are primarily focused on information delivery and interactions are limited to viewing content, navigating thru page, and occasionally submitting forms. Contents are usually static. Could be dynamic based on a particular site. Examples will be blogs, news sites, informational sites, corporate sites like intelygic.com.

We know that project requirements always change as a project progresses. It happens 100% of the time, not even 99%.
