Web Development
Marketing surfaces engineered for speed and conversion.
In short
Web development at Offsage is the design and build of fast, conversion-focused marketing sites, web applications and e-commerce platforms on Next.js and React. Performance, technical SEO and analytics are treated as build requirements rather than later additions. Landing pages start at $2,500, marketing websites at $7,500 and e-commerce platforms at $12,000.
Key takeaways
- Landing pages from $2,500, marketing websites from $7,500, e-commerce platforms from $12,000.
- Next.js and React with server rendering, so content is present in the source HTML where search engines and answer engines can read it.
- Core Web Vitals are enforced as a build constraint, not measured after launch and fixed later.
- Technical SEO foundations — canonical logic, structured data, sitemaps — ship with the build.

How this works
A website is judged on whether it loads quickly, ranks, and converts. Offsage builds on Next.js with server rendering by default, which means the content a crawler needs is present in the source HTML rather than assembled after hydration — the single most common reason a well-designed site underperforms in search.
Performance is treated as a constraint on the build rather than a report produced afterwards. Image formats and sizing, font loading, JavaScript budget and layout stability are decided during development, because retrofitting Core Web Vitals onto a finished site is materially more expensive than designing for them.
Anti-patterns are avoided deliberately: no heavy client-side animation libraries where CSS suffices, no third-party tag sprawl, no layout that shifts as assets arrive. The result loads quickly on a mid-range phone over a real connection, which is the only benchmark that corresponds to how most visitors arrive.

Questions on web development
Next.js and React with TypeScript, styled with Tailwind CSS, deployed on Vercel or your own infrastructure. Next.js is chosen for server rendering, which puts content in the source HTML where search engines and answer engines read it, and for image and font optimisation built into the framework.
Landing pages start at $2,500. The final figure depends on how much content, integration and motion is involved. A single page with a form and analytics sits at the lower end; a page requiring custom interaction and multiple integrations costs more.
Yes, and they are treated as a build constraint rather than a post-launch report. Image formats and sizing, font loading, JavaScript budget and layout stability are decided during development, and results are verified against real-device conditions rather than a desktop laboratory score alone.
Yes. Offsage implements designs produced by your team or another agency, and can also provide design direction if you do not have it. Where a supplied design would harm performance or accessibility, the trade-off is raised before implementation rather than silently changed.
Offsage builds on Next.js. Where a client needs WordPress specifically — for an existing editorial team or plugin ecosystem — that is discussed openly, and the performance and SEO trade-offs are stated before work starts.
