Questions
Web Application Development FAQs
What is the difference between a website and a web application?
A website mainly presents information, while a web application lets users log in, work with data and complete tasks: think dashboards, portals, marketplaces and SaaS products. DevionX builds both, but web applications are where custom engineering matters most.
Which technology stack do you recommend for web apps?
For most products we recommend React or Next.js on the frontend with Node.js or Python services behind a clean API, backed by PostgreSQL or MongoDB. The final choice always follows your requirements, team skills and hosting constraints.
How long does it take to build a web application?
A focused first version can ship in a few weeks; larger platforms take several months. Recent DevionX builds have gone from concept to production in roughly four months, including a platform now serving thousands of requests per day.
Who owns the source code and intellectual property?
You do. DevionX hands over full intellectual property and source control on delivery, with clean documentation, exactly as we have done for partners like 0101 Labs.
