TL;DR. An AI-native website costs €1,500–12,000+ in 2026 depending on scope. Single-page launch sites with one AI feature: €1,500–2,500. Full multilingual sites with 2-3 AI features: €3,500–6,000. Custom flagship builds with dedicated agents and integrations: starting €6,000, often more. The price gap vs traditional web isn't the AI itself — it's multilingual depth, custom integration, and the cost of doing the work right rather than templating.
How much does an AI website cost in 2026?
Here are the real ranges at TheAIgency, all-in (design, development, AI features, multilingual, codebase ownership, hosting setup, post-launch support):
| Tier | Price (EUR) | Timeline | What you get |
|---|---|---|---|
| Spark | 1,500–2,500 | 1-2 weeks | Single-page multilingual site + 1 AI feature (typically a concierge chat trained on your business) |
| Signal (default) | 3,500–6,000 | 3-4 weeks | Full 5-8 page multilingual site + 2-3 AI features (chat, dynamic content, smart forms) |
| Studio | Custom (typically 6,000–12,000+) | 4-6 weeks | Custom flagship — dedicated team, custom AI agents, integrations (CRM, ERP, payment, booking), priority support |
What's included at each tier?
Spark (€1,500–2,500): single-page multilingual site, custom design + copy, one AI feature (usually a concierge chat trained on your business), hosting + 1 month support. Best for founders or small teams who need to look credible fast.
Signal (€3,500–6,000): everything in Spark, plus a 5-8 page site, 2-3 AI features (chat, dynamic content, smart forms, etc), CMS or headless option, hosting + 3 months support. The default tier for most mid-market businesses.
Studio (custom, typically €6,000–12,000+): everything in Signal, plus custom AI agents tied to your workflows, interactive tools, dynamic personalisation, dedicated project manager, custom integrations (CRM, ERP, payment, booking), performance analytics dashboard, priority support + 6 months post-launch care.
What's not included?
- Ongoing AI agent operation — that's the Automation product line, recurring (€500–5,000+/month).
- Paid ads management or SEO retainers — we don't sell those as standalone services.
- Brand identity work — we use your existing brand. If you need logo/identity, hire a brand specialist first.
- Ongoing video content — that's the Creative product line.
Why does an AI website cost more than a templated site?
The marginal cost of "adding AI" is small — running a concierge chat trained on your docs costs €5–30/month at scale on Anthropic Claude. The cost is in the work that makes the AI useful: training the concierge on your specific business, building real multilingual architecture (not auto-translation), wiring smart forms that route to the right human, and shipping it on a stack that actually performs (Core Web Vitals, INP, accessibility).
Templated sites optimise for cost-of-build. AI-native sites optimise for what the site does after launch. Different goals, different price.
How does this compare to other ways to build a site in 2026?
| Approach | Cost | Where it wins | Where it breaks |
|---|---|---|---|
| Templated SaaS (Wix, Squarespace, Webflow) | €10–60/month | Cheap, fast, no developer needed | No real AI features, performance issues, lock-in |
| AI app builder (Lovable, v0, Bolt) | €20–25/month + your time | One-page validation, prototyping | Multi-tenant, real billing, custom AI features at scale |
| Freelance dev + GPT widget | €800–3,000 one-time | Cheap if you have a clear spec | No structural AI, often no multilingual, no ongoing improvement |
| AI-native agency (TheAIgency) | €1,500–12,000+ | Real AI features, codebase ownership, multilingual | Wrong fit if you only need a brochure |
| Big-agency custom build | €30,000–150,000 | Brand prestige, large internal teams | Slow, expensive, AI usually bolted on |
