    Our client successes

    We build our own products. That's why we know how to build yours.

    A custom website is what you pick when Webflow no longer fits: complex API integrations, interactive configurators, performance that has to stay in the web's top 5%, design that has to be impossible to mistake for a template. We code in React/Next.js with a product discipline (TypeScript, tests, monitoring) rather than a communications-agency mindset. For: SaaS companies that want a website on par with their product, brands with strong design ambition, expert sites that depend on SEO.

    Our method in brief

    Short cycle focused on Core Web Vitals. (1) Audit + scoping: business goals, journeys, keywords, target CWV. Wireframes + Figma design. (2) Development: Next.js App Router with ISR/SSG depending on content, automatic image optimisation (next/image), inline critical CSS, self-hosted fonts. (3) Technical SEO audited before launch: Lighthouse 95+, JSON-LD schema, sitemap, robots, OG. (4) Go-live + CWV monitoring (PageSpeed, Web Vitals API). Content updates via CMS or Git PRs depending on your setup.

    Stack & technologies

    Next.js 15 (App Router) or Remix, TypeScript, Tailwind, shadcn/ui, framer-motion for premium animation. Headless CMS: Sanity, Contentlayer, Storyblok depending on editorial needs. Hosting: Vercel by default, Netlify or Cloudflare Pages depending on constraints. Analytics: Plausible (GDPR-friendly), GA4 or PostHog. Forms: Resend + serverless functions. SEO: next-sitemap, schema-dts for typed JSON-LD.

    Frequently asked questions

    Do you guarantee Core Web Vitals?+

    Yes, provided reasonable content on the client side. We deliver with Lighthouse 90+ on mobile, LCP < 2.5s, INP < 200ms, CLS < 0.1. If you later load heavy third-party scripts (chat, A/B testing, chained marketing automation), scores can drop — we document the impact of each addition.

    Can content be edited without a developer?+

    Yes, via a headless CMS (we recommend Sanity). Your editors publish like in Notion, and the site rebuilds automatically. For small sites, we can also structure content as MDX in the Git repo, which is simpler to maintain.

    Why not WordPress?+

    WordPress is still relevant for high-volume editorial blogs with a non-technical team. For a modern SaaS marketing site with demanding CWV, clean integrations and original design, custom React is faster, more secure and more maintainable. It's a question of context, not dogma.

    What if we need changes after delivery?+

    Three options: (1) monthly maintenance retainer, (2) on-demand tickets at the dev rate, (3) you take over with your own team. The code is documented, in strict TypeScript, with tests on critical logic — any React team can pick it up in a few days.
