FAQ
Common questions about this family.
How is this different from a regular website?
A custom web application is built around specific business logic, user roles, and workflows — dashboards, portals, or automation tools — rather than presenting content to visitors like a marketing website.
Do you build the frontend, backend, or both?
Both, depending on scope. Frontend Development covers interface and interaction work; Custom Web Application Development covers full-stack build including data models and integrations.
