When a Website Is Not Enough, We Build Software That Scales

There is a point where a website stops being enough

When a business needs logic, users with logins, recurring payments, real-time dashboards, inventory management, complex bookings, it needs a web application, not a website. A web app is not a site with an extra form. It is real software: authenticated, database-driven, API-connected, and built to handle the operations that static pages cannot.

We build robust, secure, and scalable applications. From internal dashboards that replace spreadsheet chaos, to client portals that give customers self-service access, to full SaaS products designed to generate recurring revenue. Whether the backend runs on Supabase for managed PostgreSQL or on a dedicated Docker environment, we choose the architecture that fits the problem, not the one that sounds trendy.

What we deliver

Every web app project is scoped around the real problem the business is trying to solve. We do not build technology for the sake of it. We build the minimum viable system that solves the problem, then help it evolve.

Typical deliverables include:

• Secure authentication, login, registration, social login via Google or Apple, two-factor authentication using standards like TOTP, and session management
• Optimized databases, relational data through PostgreSQL (via Supabase or PlanetScale), designed for performance and scalability
• RESTful or GraphQL APIs, for integration with any external service, following OpenAPI standards where applicable
• Custom admin panels, for complete business management, built to match internal workflows
• Payment processing, through Stripe (Payment Links, Checkout, Connect), PayPal, Easypay, and MB WAY
• Full GDPR compliance, data management, right to erasure, and data export, aligned with European regulation
• Technical documentation, for your team or future developers

Why architecture decisions matter early

The wrong technical decision at the start of a project can cost ten times more to fix later. Choosing the wrong database, the wrong authentication provider, or the wrong deployment strategy creates compounding problems that get harder to untangle as the product grows.

That is why we invest time in architecture before writing code. We define the data model, the API surface, the authentication flow with tools like NextAuth.js or Clerk, the deployment strategy, and the scaling path before the first line of production code is written. When the foundation is right, everything else moves faster and costs less.

For complex projects, we often recommend starting with a technical consulting session to map the architecture before committing to development.

The MVP approach

We believe in launching fast and learning from real users. An MVP is not a broken product, it is a focused product. It solves one problem well enough to validate whether users need it, and it is built with enough architectural discipline to scale when the answer is yes. This aligns with the lean methodology documented by Y Combinator and practiced across the most successful product companies.

Most web apps we build start as MVPs and evolve through iterations. The first version proves the concept. The second version deepens the features users actually use. The third version starts optimizing for growth. This approach reduces risk, controls cost, and keeps the product aligned with real market feedback.

How x078 supports the operational side

A web app is not like a static website. It runs on servers, connects to databases, processes payments, and handles user data. That means it needs ongoing operational support: monitoring, backups, security patches, dependency updates, and performance optimization.

x078 provides the infrastructure layer that keeps applications running cleanly. Through managed hosting, we handle server management on Hetzner or DigitalOcean in isolated Docker environments, with automated backups, SSL certificates, and monitoring. Through ongoing maintenance, we handle the code-level work that keeps the application healthy as it grows.

Who this is for

Web apps make sense for startups launching MVPs, companies with internal processes to digitalize, businesses that need client portals, complex booking platforms, and SaaS tools. If the problem involves data, users, logic, and integration, it probably needs a web app.

Pricing

Web application projects start from €15,000 for a production-ready MVP. This includes architecture scoping, UI/UX design in Figma, frontend and backend development, authentication, a database layer, and deployment to a managed environment. More complex applications with multiple user roles, third-party integrations, or real-time features are scoped individually.

For businesses that need both a marketing website and a web app, building both in the same project and design system is significantly more efficient than treating them as separate engagements.
