Top Website Builders for Marketing Agencies Managing Multi-Client Sites

Managing websites for multiple clients is a core responsibility for marketing agencies. The digital age has ushered in an expectation for seamless online presence, and agencies must deliver high-performing, easily customizable, and secure websites—often under tight deadlines. It’s a complex task, especially when working across industries and client requirements.

TLDR: For marketing agencies juggling multiple clients, the right website builder is crucial. Tools like Webflow, Wix Studio, and WordPress (via managed hosting) offer scalability, multi-site management, and customizability. Look for platform features like team collaboration, role management, and performance optimization. This guide outlines the top choices to streamline your workflow and enhance your service offering.

What Marketing Agencies Need in a Website Builder

Agencies face a unique set of challenges when it comes to building and managing websites:

• Multi-client management: Ability to handle numerous sites under a single login or dashboard.
• White-label capabilities: Branding and ownership options that match the agency’s identity.
• Team collaboration features: Multiple user permissions and real-time editing capabilities.
• Performance and SEO: Built-in optimization tools or easy integration with third-party SEO solutions.
• Client handoff and training: Easy-to-use interfaces for non-technical end clients.

Choosing the wrong builder can mean countless hours lost in maintenance and a struggle to deliver top-tier digital experiences. Below is a look at website builders designed to simplify this process for agencies of all sizes and industries.

1. Webflow – A Versatile Powerhouse for Agencies

Webflow stands out as a builder that serves both developers and designers. With its high degree of customizability and professional look, it’s increasingly the go-to platform for agencies who want full control without sacrificing efficiency.

• Multi-site dashboard: Manage all client projects from a single Workspace.
• Custom code support: Inject JavaScript, CSS, and HTML as needed.
• Client editor: A simplified interface where clients can change content without altering the design.
• White-labeling: Agency plans include branding tools.

Webflow also offers advanced CMS features, perfect for dynamic content like blogs, portfolios, and event listings. Plus, its staging and publishing workflow is simple but robust.

Best for: Agencies needing flexible design control, CMS capabilities, and enterprise scalability.

2. Wix Studio – Chosen for Collaboration

Wix Studio, formerly known as Editor X and built on the Wix platform, is purpose-built for professional teams. It lets agencies design responsive websites with pixel-perfect precision and manage tasks from one collaborative platform.

• Multi-user environment: Assign team roles, collaborate on live projects, and track changes.
• Client dashboards: Simplified access for clients to view or edit content.
• Drag-and-drop editor: Intuitive UI that speeds up prototyping and iteration.
• Scalable hosting and security: Powered by Wix’s secure infrastructure with integrated analytics.

Wix Studio is especially well suited for agencies delivering websites to clients in industries like hospitality, local services, or personal branding—sectors that value visual design and quick delivery.

Best for: Agencies focused on rapid development, visual appeal, and streamlined collaboration with clients.

3. WordPress with Managed Hosting (e.g., WP Engine)

WordPress powers over 40% of the internet, and with good reason. When paired with managed hosting services like WP Engine or Kinsta, it becomes a stable, fast, and scalable environment for high-end website delivery.

• Unlimited customization: Use themes, custom post types, and thousands of plugins.
• Multi-site capabilities: Run entire networks of sites from a single WordPress installation.
• Client permissions: Role-based access control tailored to each client’s needs.
• White-labeled client portals: Using third-party plugins, offer agency-branded dashboards.

Though WordPress has a steeper learning curve, it excels in SEO, performance tuning, and integrations, especially for enterprise-level sites or when handling special functionality, like booking systems or eCommerce.

Best for: Agencies with technical experience looking for fully customizable solutions for diverse clients.

4. Duda – Built Exclusively for Agencies

Duda is a website builder designed specifically for agencies and SaaS platforms aiming to produce large quantities of client websites with consistent structure and branding.

• Multi-site management: Easily switch between hundreds of client websites.
• Team collaboration tools: Built-in workflows and permissions.
• Template libraries: Reusable layouts speed up production cycles.
• Client feedback tool: Clients can comment directly on the design during reviews.

Duda incorporates a white-label agency dashboard, making it simple for agencies to manage internal staff and external clients from a single frontend. It also offers automation and API access for scaling operations.

Best for: Agencies operating at scale who need efficiency, templating, and client-facing tools.

5. Squarespace – Simplicity Meets Style

While not as agency-oriented out of the box, Squarespace still earns a spot for its unbeatable aesthetic templates and recent expansion into more pro features like Squarespace Circle for developers and agencies.

• Beautiful templates: Ideal for clients in creative industries.
• Commerce and booking tools: Built-in tools for product and service-based businesses.
• Simple client management: Easy to train end-users and transfer sites upon completion.
• Developer mode: Limited ability to inject code or use custom frameworks.

If your focus is on branding-focused, visually stunning sites updated infrequently, Squarespace fits well. Its limitations in scalability and collaboration tools, however, may slow teams managing dozens of sites.

Best for: Boutique agencies working with design-focused clients.

Key Features to Evaluate When Choosing a Website Builder

Before committing to a platform, agencies should evaluate the following functionalities:

• Integrated analytics: Look for native or easily connected analytics tools for client reporting.
• Security: Ensure SSL, DDoS protection, and data backups are part of the package.
• Client billing options: Some platforms allow billing clients directly through your agency account.
• Speed and performance optimization: Especially crucial for SEO and UX.

Conclusion

For marketing agencies, the ability to efficiently manage multiple websites determines client satisfaction and internal productivity. Whether you’re delivering 3 or 300 websites a year, the platform you use must match your needs in terms of scalability, customization, and support.

Webflow and Wix Studio lead the way in collaboration and customization, while WordPress with managed hosting offers the most flexibility. Duda provides unmatched workflow optimization for agencies focused on high output, and Squarespace brings visual excellence to the table for creative industries.

Ultimately, the right website builder empowers your team, impresses your clients, and gives your agency a professional edge in an increasingly competitive digital marketplace.
