Frequently asked questions
Useful answers first.
What is the difference between a website and a web app?
A website mainly explains and guides. A web app also supports signed-in tasks, changing data, permissions, system responses, and repeated product workflows.
Does Diffwise.app build Next.js and React applications?
Yes. The team can build Next.js and React product interfaces when they fit the product, rendering, performance, and maintenance requirements.
Can a web app connect with an existing API?
Yes. The first technical review identifies current contracts, authentication, validation, failure behavior, and required changes before interface delivery starts.
