Have a Web Application Built — Custom Web Apps & SaaS_
You have an idea that goes beyond a brochure website — a dashboard, a customer portal, a SaaS platform, or an MVP that models real business logic. Benetos builds exactly that: bespoke web applications with a modern stack, clear architecture, and thoughtful operations.
When do you need a web application instead of a standard website?
A standard website is sufficient for presence, content, and simple lead forms. As soon as user accounts, role-based permissions, dynamic dashboards, complex forms, automation, or third-party integrations enter the picture, website builders and CMS themes hit their limits. A custom web application maps your business logic precisely — without the compromises of a generic product. Typical scenarios: a B2B customer portal, an internal reporting tool, a booking-based platform, or a SaaS product you want to market yourself.
What Benetos builds: custom projects, SaaS platforms & PWAs
The studio develops custom web apps and SaaS platforms tailored to your users and your growth plans. This includes Progressive Web Apps (PWA) for mobile access without app store friction, and native iOS apps with Swift and SwiftUI when a native presence is strategically worthwhile. Every project starts with a clear scope: which core features does the MVP need? What can come later? The result is a solution that launches quickly and scales afterwards — instead of a monolithic system that takes months before real users can work with it.
Tech stack & operations: Next.js, TypeScript, PostgreSQL, Vercel
Benetos relies on a production-proven stack: Next.js 15 with App Router and React Server Components for fast load times, TypeScript for maintainable code, PostgreSQL with Prisma as a type-safe ORM. Hosting runs on Vercel (region fra1 — Frankfurt), guaranteeing low latency for DACH users. Observability is provided by OpenTelemetry, Datadog, and Grafana so that errors and performance bottlenecks are visible early. The 99.9 % uptime SLA is backed by monitoring, automated deployments, and incident response — not just a paper promise.
Process: from intro call to production-ready MVP
The process starts with a free 30-minute intro call to discuss requirements, target audience, and scope. A written fixed-price proposal follows — no hourly roulette, no open invoice at the end of the month. Standard websites are delivered in 2–4 weeks; custom projects and SaaS MVPs realistically take 1–3 months depending on scope. After launch, Benetos can take over ongoing operations: monitoring, updates, security patches, and scaling, so you can focus on your product.
Costs: fixed price after scoping, not per hour
The cost of a custom web application depends directly on scope — quoting a flat number without knowing your requirements would be misleading. What is clear: after the intro call you receive a fixed price that covers the full development scope, with no hidden extras. Standard websites start in the low four-figure range. Custom projects and SaaS platforms are quoted individually. To put it in context: a cleanly built MVP with professional operations typically costs far less than the risk of rebuilding a poorly executed product later.
