Custom web applications and SaaS platforms
When a website is no longer enough, you need an application: accounts, roles, data, payments and business rules. We design it, build it and run it in production.
XAB Solutions develops custom web applications in Tunisia: multi-tenant SaaS platforms, client and B2B portals, marketplaces, booking systems and member areas, with Next.js, NestJS, PostgreSQL and real-time features.

What people often ask us.
Which technologies do you work with?
Mainly Next.js, React and TypeScript on the front end, NestJS, Node.js, Python and Go on the server, PostgreSQL and Redis for data. The choice depends on the project.
Do I own the code?
Yes, once the project is paid, the source code and all access are handed over to you.
Can you take over an existing application?
Yes, after a code audit to tell you honestly what can be kept.
Web app or mobile app?
A web app opens in the browser, on computer and phone, without going through the stores: ideal for business tools and portals. A mobile app adds notifications and offline use. Many projects start with the web.
What is an MVP?
A first version that contains only the essentials to test your idea with real users. It is built cleanly so it can evolve afterwards.
Can you build a booking platform?
Yes: time slots, seats, reminders, deposit payment and a dashboard to manage bookings.
