Custom web applications
Turning a business need into an application.
NuWide designs custom web applications tailored to your users, your processes, and your data—from the interface to the infrastructure.
Real-world applications
An application starts with what it’s meant to do.
Every organization has its own processes, users, and goals. A custom web application adapts to your needs rather than forcing you to conform to those of a standard tool.
Portals & customer areas
Secure spaces for your customers, partners, or users.
Dashboards & management
Activity tracking, data visualization, reporting.
Internal tools
Interfaces to simplify and centralize daily work.
SaaS & online services
Applications accessible via a web browser.
Workflows & automations
Business processes, validations, automated tasks.
Back-office & administration
Content, user, and settings management.
Experience
An interface designed with its users in mind.
A single application can cater to different user profiles, each with specific needs, permissions, and user journeys.
Client / User
A simple interface tailored to your needs.
Team
Tools to collaborate and boost efficiency.
Administrator
Comprehensive management and advanced permissions.
Partner
Dedicated access and specific features.
UX/UI Clear, efficient user journeys.
Responsive An optimal experience on all screens.
Accessibility Inclusive and usable interfaces.
Permissions Access rights tailored to each role.
From frontend to data
An application is a complete system.
From the front end to the infrastructure, each layer plays a role in delivering a high-performance, secure, and scalable application.

Frequently asked questions
Custom web applications: The essential questions.
A custom web application is designed around specific needs, processes, and users, rather than being adapted to the limitations of a standard tool. It is accessible via a browser and can integrate interfaces, business logic, data, APIs, and services.
Customer portals, internal tools, dashboards, business applications, multi-user platforms, online services, workflows, and connected interfaces can all take the form of a web application.
Yes. An application can complement an existing system, replace only certain interfaces, connect to existing data, or gradually modernize an architecture.
NuWide primarily uses Python and Django for the backend, as well as Nuxt & Vue.js for frontend interfaces. The specific technologies chosen depend on the project’s architecture, constraints, and anticipated evolution.
The duration depends on the scope, features, integrations, technical constraints, and the level of design required. NuWide begins by defining the requirements before establishing a schedule tailored to the project.
Depending on the project, NuWide can provide maintenance, monitoring, hosting, functional upgrades, and ongoing technical support.
