FAQ

Frequently Asked Questions

Common questions about our web application development services.

How much does a custom web application cost?
Costs depend on complexity, features, and timeline. A simple web app starts at $5K-15K. A mid-complexity SaaS platform ranges from $20K-50K. Enterprise-grade applications can exceed $100K. We provide detailed estimates after a free discovery session.
What technologies do you use for web development?
We primarily use React and Next.js for frontends, Node.js and Python for backends, and PostgreSQL or MongoDB for databases. We choose the stack that best fits your project's requirements, team expertise, and scalability needs.
How long does it take to build a web application?
A simple MVP can be built in 6-8 weeks. A full-featured web application typically takes 3-6 months. We use agile development with 2-week sprints, so you see working features from the first sprint.
