Vezert is a Next.js web development agency building B2B marketing sites, multilingual corporate hubs, and multi-tenant portals on hybrid SSG/ISR, strict TypeScript, and Tailwind CSS with LCP <1.2s, INP <100ms, 95+ Core Web Vitals, hreflang, Schema.org JSON-LD, llms.txt, €0–€50/mo Vercel/AWS edge hosting, and 100% Git IP ownership.
Marketing & Corporate Site
2–4 wks · WordPress & Webflow replacement · Hybrid SSG/ISR
Multilingual Headless Hub
4–6 wks · Sanity, Payload, Contentful, Strapi
Portals & Enterprise Apps
6–8 wks · Multi-tenant web apps · Enterprise rollouts €25,000+
Why B2B teams outgrow WordPress, Webflow, and bloated themes.
Visual builders stall once multi-locale routing, custom calculators, or InfoSec audits hit €10,000+ annual CMS licenses and 3.8s mobile loads.
- Seat & tier inflation: Enterprise CMS licenses exceed €10,000 yearly with rigid localization and routing rules.
- Mobile speed drag: Third-party scripts and heavy themes push mobile loads past 3.8 seconds.
- Engineering gridlock: Product developers avoid brittle PHP plugins, trapping marketing in six-month agency queues.
Typed Next.js infrastructure marketing can actually publish on.
Senior React/Next.js engineers and conversion UX designers ship composable section libraries with live preview and strict CI/CD gates.
- Autonomous publishing: Marketing launches pages instantly with visual live preview and on-demand ISR.
- Strict TypeScript core: Clean CI/CD pipelines, tokenized Tailwind CSS, and sub-100ms INP responsiveness.
- Edge scale & IP: Global Vercel or AWS edge hosting at €0–€50/mo with full Git ownership.
Six-Stage Next.js Delivery Sprint
Senior architects own system design, data modeling, and PR reviews while automated checks enforce Core Web Vitals, accessibility, and SEO parity on every commit.
01. Architecture & URL Audit
We crawl your existing site, map every ranking URL and backlink, define SSG vs ISR rendering rules per route, and lock the redirect matrix.
02. Tokenized Figma System
Designers craft responsive layouts and interactive UI states using design tokens that map 1:1 to Tailwind CSS configuration and React props.
03. Strict TypeScript & Next.js Build
Engineers build modular sections, AVIF/WebP image pipelines, zero-CLS font loading, and lean client islands that keep mobile LCP under 1.2s.
04. Headless CMS & CRM Integration
We wire Sanity, Payload, Contentful, or Strapi with live preview webhooks, plus server-side HubSpot, Salesforce, and GDPR-compliant analytics.
05. Automated CWV, WCAG & GEO Gates
Playwright, Lighthouse CI, and schema validators verify 95+ Core Web Vitals, WCAG 2.2 AA contrast/keyboard flows, hreflang, and llms.txt.
06. Zero-Downtime Edge Cutover
We deploy to your Vercel or AWS account, verify 301/308 redirects and Search Console indexing, and hand over full Git documentation.
Production Next.js Architecture Deliverables
Concrete engineering artifacts included in your repository, built so internal developers and InfoSec reviewers never have to reverse-engineer our work.
Hybrid SSG & On-Demand ISR
Static edge speed for core commercial pages combined with webhook-triggered Incremental Static Regeneration so CMS edits go live in seconds.
Strict TypeScript & Tailwind Tokens
End-to-end type safety across CMS payloads, API routes, and UI components, backed by a documented Tailwind CSS design system.
Headless CMS Live Preview
Structured content modeling in Sanity, Payload, Contentful, or Strapi so marketers compose new landing pages without developer tickets.
Sub-Second Core Web Vitals
Mobile LCP under 1.2s, INP below 100ms, next/image AVIF pipelines, and deferred third-party script orchestration via Partytown or server proxies.
Native Multilingual & Hreflang
Localized URL segments per country, automatic hreflang and canonical tags, and locale-specific XML sitemaps ready for European expansion.
AI Search & Schema.org Graph
Typed JSON-LD for Service, SoftwareApplication, HowTo, and FAQPage, paired with clean Markdown mirrors and llms.txt for AI citation engines.
Serverless API & CRM Pipelines
Edge middleware and protected API routes connecting forms, ROI calculators, and OTP flows directly to HubSpot, Salesforce, or Segment.
Vercel or AWS Edge Deployment
CI/CD preview URLs on every pull request, security headers (CSP, HSTS), and €0 to €50/mo hosting inside your own cloud organization.

Next.js Agency Build vs Legacy CMS vs Retainer Agencies
Side-by-side performance, editorial autonomy, and 24-month total cost of ownership before you commit budget.
| Architecture & Commercial Metric | WordPress / Webflow Enterprise | Vezert (Next.js + Headless CMS) | Traditional Enterprise Agency |
|---|---|---|---|
| Time to Production Launch | 4 to 8 weeks (theme + plugin wrangling) | 2 to 4 weeks (4 to 6 headless/multi-locale) | 12 to 24 weeks |
| Mobile Core Web Vitals (LCP / INP) | 2.4s to 4.2s LCP, heavy DOM bloat | <1.2s LCP, <100ms INP, 95+ score | Best-effort, rarely contractually gated |
| Multilingual Routing & Hreflang | Paid per-locale add-ons or messy subfolders | Native localized URLs + automated hreflang | Billed as separate localization phase |
| 24-Month Hosting & Seat Overhead | €7,200 to €24,000+ in SaaS/VIP tiers | €0 to €1,200 on Vercel or AWS edge | €18,000 to €48,000+ mandatory hosting SLA |
| Security & Compliance Surface | Plugin vulnerabilities or closed SaaS box | Static edge assets, CSP/HSTS, GDPR-ready | Depends on legacy DXP stack |
| Codebase & IP Ownership | Locked to proprietary builder or PHP theme | 100% clean Git repo + Figma tokens | Often tied to proprietary agency framework |
| Typical Build Investment | €4,000 to €15,000 + recurring seat tax | from €4,500 fixed EUR scope | €30,000 to €85,000+ |
