Frequently Asked Questions (FAQ)
What is full custom web development?
Full custom web development involves creating a web application or platform from scratch, specifically to meet your business’s unique needs and objectives. Unlike prefabricated solutions (CMS like WordPress, Shopify), everything is custom-designed and coded, from the technical architecture to the user interface, offering maximum flexibility, performance, and scalability.
What are the advantages of a full custom solution compared to a standard solution?
The advantages are numerous: optimized performance because the code is lightweight and without superfluous features; enhanced security thanks to a specific architecture and rigorous development practices; unlimited scalability, allowing features to be added or modified easily; perfect alignment with your business processes and brand identity; and full intellectual property of the source code.
How long does it take to develop a full custom solution?
The timeframe heavily depends on the project’s complexity and scope. A Minimum Viable Product (MVP) project can take 3 to 6 months, while a complex business application or a large-scale platform may require 6 to 12 months or more. We work in phases (analysis, design, development, testing, deployment) to ensure transparent delivery and regular validation points.
How does a full custom development project start with your team?
The process begins with a free initial consultation to understand your needs and objectives. Then, we conduct an in-depth analysis and propose a detailed technical and commercial offer. Once validated, we move to the design phase (UI/UX), then to iterative development, testing, and finally to deployment and maintenance. Collaboration and regular communication with your teams are at the core of our approach.
