The five platforms agencies actually choose between in 2026 are WordPress (+MainWP), Duda, Wix Studio, Webflow, and Pubner — and the right one depends on whether your team writes code, how many sites you run, and who should own the result. Quick answer: WordPress for maximum ecosystem, Duda for no-code white label, Wix Studio for the budget segment, Webflow for design-led studios, Pubner for developer agencies that want AI plus code ownership. The details — and the honest trade-offs — below.
How we compare
Five criteria that decide the day-to-day of an agency: client management at scale (many isolated sites, team roles), white label, AI that saves real hours, total cost across a fleet, and exit — what you and your client hold if you leave the platform.
WordPress + MainWP — the default, and the debt
Best for: agencies that monetize maintenance and need a plugin for everything. Still ~60% of the CMS market (slowly declining), free core, clients know the brand. Agent infrastructure is arriving (Abilities API + MCP, Elementor's Angie), but fragmented. The trade: every site is a separate install — security, updates, and plugin conflicts multiply, and MainWP/ManageWP ($29/month / ~$1–2 per site) only make the zoo manageable. Many agencies profit from that pain via maintenance retainers; the question is whether those hours are your best margin.
Duda — white label without code
Best for: no-code agencies selling volume sites under their own brand. The most agency-shaped product on this list: client dashboard, team roles, white label, site-to-site content injection, and a serious AI stack (site/section generation, bulk SEO, widget builder, its own MCP server) — with AI resellable to your clients via permissions. Pricing per site: Agency $52/month for 4 sites, then ~$17/site; White Label from $149/month. The trade: a closed builder — no backend or API of yours, and export is a static, minified ZIP that loses editability.
Wix Studio — the budget workhorse
Best for: high-volume, price-sensitive client work. Wix's agency product grows fastest among major platforms (+22–32%/year): client management, collaboration, $19–159/month, and the Astro AI assistant across the dashboard (with the Harmony/Aria agent announced). The trade: lock-in with no code or API, and a ceiling — "good enough" holds for the lower segment, not for custom logic or demanding brands.
Webflow — the design flagship
Best for: design-led studios shipping premium marketing sites. Best visual control in the industry and the most advanced AI in the category (full site generation, full-stack apps from a prompt, built-in SEO/AEO audits), plus a mature partner ecosystem. Per-site plans ($15–39/month each) stack up across a fleet, and export is static HTML without CMS pages — a living content site can't really leave. Studios that go, go for control and code, not price.
Pubner — AI plus code ownership
Best for: developer agencies and freelancers who want the agency layer and the code. An AI-driven agency CMS on Laravel: one platform where each client site is an isolated tenant — Hub overview, RBAC, custom domains, $20/month. The AI copilot works over each site's actual data (content drafts, SEO files, conversational page building with live preview). The differentiator no one above offers: Full Export hands you your Twig themes and all your content as portable JSON — clean code and data, no Pubner lock-in. The honest trade: no white label yet, a smaller template ecosystem, and custom work assumes a developer (that's the audience).

The one question that picks your platform
Who owns the site when the contract ends? If the answer doesn't matter to your clients — Duda, Wix Studio, or Webflow will serve you well within their segments. If it does — you're choosing between the WordPress zoo (ownership with debt) and Pubner (ownership with one maintained stack and an AI copilot). That's the 2026 split: AI is everywhere on this list; ownership isn't.
