The answer, as recorded

## The short version For most agencies, the honest answer is you'll end up running **two or three** of these, not one - a mainstream option for clients who want cheap and familiar, and a better one for flagship builds. Here's what I'd actually reach for, in order: **1. WordPress (with ACF Pro, on WP Engine or Kinsta)** Still the default for a reason: clients already know the admin, you can hire for it cheaply, and the plugin ecosystem kills features you'd otherwise build. The agency-grade version of this isn't "WordPress + page builder soup" - it's ACF Pro giving clients structured fields for the content they own (staff, locations, case studies) instead of layout-heavy pages they can break. Hosting: WP Engine if you want the bundled agency toolchain (Local, ACF, Flywheel) and SOC 2/ISO paperwork; Kinsta if you want more traffic allowance per dollar and faster benchmarks. Main cost: at three-plus sites you're maintaining three-plus installs, databases, and update cycles. **2. Webflow** The best margin machine for design-led agencies doing marketing sites. No maintenance burden, no plugin CVEs, strong performance out of the box, and the workspace model is genuinely built for agencies - build in your workspace, transfer to the client's, bill them for hosting. The Partner/Expert certification tiers also drive inbound leads. Weak spot: anything with real application logic or complex data relationships. **3. Storyblok** My first pick if you're going headless. The visual editor is the one that actually survives client contact - in-context drag-and-drop with live preview, so most clients are productive the same day. Component-based, so you build a block library once and reuse it across accounts. **4. Sanity** Where I'd go for content-heavy or genuinely complex modelling - custom editing experiences, real-time collaboration, and the most flexible schema story of the group. Costs you more dev time up front than Storyblok; worth it when the content model is the hard part. **5. Craft CMS** The sweet spot between WordPress and full headless. Excellent multi-site, clean editor UX, serious SEO control, and a developer-first codebase that ages well. Underrated for agencies with one strong PHP dev and clients who need more structure than WordPress gives without a full decoupled rebuild. **6. Prismic** Specifically if your business *is* shipping websites repeatedly. Slice Machine plus TypeScript generation means a shared component library across clients, which compounds - each project gets cheaper than the last. **7. Statamic** Only if your team is already Laravel. Flat-file or database, minimal dependencies, and you keep full control of the stack. Narrow fit, but the right fit is a very good one. ## Two things worth weighing in 2026 Agentic tooling is the current differentiator - Contentful, Sanity, and Storyblok are all shipping MCP servers and agent APIs, which matters if you're selling AI-assisted content ops to clients. And **Contentful** I'd deliberately put outside my top list: it's a fine enterprise platform but priced for enterprise, and for typical agency retainer work Storyblok or Sanity gets you further per dollar.
