Frequently asked questions

How much does a showcase website cost?

A simple showcase site starts from €800. A premium site with animations, advanced CMS and technical SEO ranges from €3,000 to €8,000. The price depends on the number of pages, features and customisation level. This configurator gives you a personalised range in 3 minutes.

How much does custom web application development cost?

A functional SaaS MVP typically runs €8,000–20,000. A full product with payments, back-office, roles and integrations: €20,000–50,000. Enterprise projects can exceed €50,000. The configurator calibrates the range based on your project type and context.

How long does it take to build a web project?

A showcase site: 2–6 weeks. A SaaS MVP: 6–16 weeks depending on complexity. A full application with back-office and integrations: 3–6 months. The free 30-minute diagnostic establishes a precise timeline based on your scope.

What is the difference between a showcase site and a web application?

A showcase site presents your business (pages, forms, SEO) without complex business logic. A web application manages user accounts, data, workflows and integrations. The boundary depends on your needs — the configurator helps you identify the right type.

Why do a free diagnostic before starting?

The 30-minute diagnostic scopes the project, validates technical options and refines the estimate. Arriving with a structured brief (via this configurator) makes the call immediately operational. No commitment — it's a basis for deciding together.

Does Antesy work with both startups and established SMBs?

Yes. Antesy works with startups in MVP phase and SMBs industrialising their processes or modernising existing systems. The approach adapts to each context: speed and frugality for an MVP, robustness and governance for an established structure.
