Frequently Asked Questions

Here's a list of FAQs that will help you learn more about DianApps.

A website delivers content, pages, blog posts, product listings. A web application lets users do things, manage accounts, process transactions, run reports, collaborate in real time. Gmail is a web app. A company blog is a website. The technical difference matters because web apps need authentication, state management, and backend logic that static sites don't. That makes them more complex and more expensive to build.

We choose based on the project, not on preference. React and Next.js for frontends that need speed and SEO. Node.js or Python (Django/FastAPI) for backends. PostgreSQL or MongoDB for databases. AWS, GCP, or Vercel for infrastructure. For real-time features, we use WebSockets or Server-Sent Events. We'll recommend what fits and honestly tell you when a simpler stack will save you money.

We do. PWAs give you an app-like experience, push notifications, offline mode, home screen install, without requiring App Store submission. They're excellent for content platforms, e-commerce, and internal business tools. Cost is typically 20-30% less than building a native mobile app, with the trade-off being limited access to device hardware.

The cost of custom web application development depends on the application's complexity, required features, UI/UX design, technology stack, third-party integrations, security requirements, and development timeline. A simple web application typically requires less investment than a complex SaaS platform, marketplace, enterprise system, or application with advanced AI and automation capabilities.

Modern web applications can be built using technologies such as React, Angular, Vue.js, Node.js, Python, PHP, Java, and cloud platforms. The right technology stack depends on the application's requirements, expected traffic, scalability needs, security requirements, integrations, and long-term business goals.

Simple web apps (dashboards, internal tools) start at $30,000-$60,000. Mid-complexity apps with user roles, payments, and API integrations run $60,000-$200,000. Enterprise SaaS platforms with multi-tenancy, advanced security, and real-time features cost $200,000-$500,000+. The cost depends mainly on the number of user roles, integrations, and data complexity.

Yes, we've built 80+ SaaS products. A typical SaaS build includes multi-tenant architecture, subscription billing (Stripe), role-based access control, analytics dashboards, and API layer for third-party integrations. Most SaaS MVPs take 4-6 months. Full platforms with advanced features take 8-14 months.

Every web app we build includes OWASP Top 10 protection, encrypted data at rest and in transit, role-based access control, input validation, and SQL injection prevention. For regulated industries, we add HIPAA compliance (healthcare), PCI-DSS (payments), or SOC 2 readiness (enterprise SaaS). We run penetration testing before launch on all production applications.

The development timeline depends on the scope and complexity of the web application. A basic MVP can be developed relatively quickly, while complex applications with multiple user roles, dashboards, integrations, real-time features, and advanced functionality require a longer development process. Proper planning, prototyping, development, testing, and deployment are essential for building a reliable application.

Yes. Developing a Minimum Viable Product (MVP) allows businesses and startups to launch a web application with its most essential features before investing in a complete product. This approach helps validate the business idea, gather real user feedback, test market demand, and prioritize future development based on actual user behavior.
