WordPress, Next.js, Webflow, headless. Choosing the right web architecture in 2026.

Most agency briefs ask the wrong first question. They ask which platform we should use. The right question is what the site needs to do. Platform falls out of that.

Most agency briefs ask the wrong first question. They ask which platform we should use. The right first question is what the site needs to do, plus who will run it after launch. Platform falls out of that. Here's how we map it.

The five modern options.

WordPress. The default of the last decade. Open source. Massive ecosystem. Editable by non-technical team members. Strong for content sites. Weak for performance. Vulnerable to plugin bloat plus security issues. Still right for plenty of small businesses. Wrong for premium positioning unless rebuilt from a clean theme.

Webflow. A visual site builder producing decent code. Editable in-browser. Good for designers without a dev team. Locked to their hosting. Limited at scale or for custom integrations. We recommend it for clients who need full self-service editing without developer support.

Next.js or Astro plus Markdown. A modern static-or-server-rendered stack. Fast. Owned by you. Edits happen in code. Right when content updates are rare. Requires development to evolve.

Next.js plus Payload, Sanity, or Contentful. Same modern frontend, plus a headless CMS giving non-technical people a clean admin. Best of both worlds. Slightly more setup. Where most premium small-business sites land in 2026.

Custom build, no CMS. Just code. Useful when the site is small enough that running a CMS exceeds the cost of editing code. Or when the site is extremely custom. Rare in pure marketing context.

How we choose. Three questions.

How often will content change. Weekly means a CMS makes sense. Rarely means a leaner setup with the studio handling updates on retainer. Clients overestimate this answer. They think they'll edit weekly. They don't.

How long will the site live before its next redesign. Three years is the realistic answer. If two, optimise for time-to-launch. If five, optimise for portability. You don't want to redesign plus re-platform at the same time.

What does the site need to integrate with. CRM. Email service. Payment. Calendar. Analytics. Each integration adds work. Some platforms make integration easier than others.

What we usually pick. Default is Next.js plus a lightweight CMS like Payload, hosted on Vercel. Editable by non-technical team members through a browser. Fast. Owned by you. Easy to evolve. We pick differently when there's a reason. Heavy editorial workflow with multiple authors, we lean Sanity. Pure brochure with no edits expected, content as code, no CMS. Strong existing WordPress with SEO equity, keep it, improve the theme.

The migration question. The biggest cost we see is when a business re-platforms unnecessarily. If your WordPress site works and has good SEO, leave it alone. Spend the budget on a redesign or a content programme. Most "we need a new platform" briefs are actually "we need a new design."

The risk question. Modern stacks are faster, cleaner. They require developers to evolve. WordPress is slower, messier. Anyone can find a WordPress developer. There's a real tradeoff between technical excellence plus operational fragility. Pick deliberately, knowing what you're trading.

Our position. The right architecture is the one letting your team do the work they actually need to do, on a stack you don't have to babysit. We make this call on every project. Most briefs arriving with "we want a Next.js site" haven't thought about whether Next.js is right for them.
