Website builder for an agency that builds sites for many clients

If you’re building and managing websites for many clients, I’d start with Duda. It’s built around agency workflows: centralized client-site management, controlled client access, feedback tools, and optional white-labeling. (duda.co)

Also consider:

• Wix Studio — a good fit if you want a broad design-and-business platform, with multi-site management, team collaboration, and client handoff tools. (wix.com)
• Webflow — a strong option when design flexibility and custom interactions matter most; it supports handing site-plan billing to clients. (help.webflow.com)

Quick pick: Duda for streamlined agency operations; Wix Studio for an all-around platform; Webflow for more design control. Before choosing, check how each handles per-site hosting fees, client editing access, and ownership transfer—those details can matter a lot once you have many sites.

The best pick depends on whether you want to resell under your own brand, how many sites you run, and whether clients need to own their sites outright. Here's how the main options compare based on current sources, which are mostly vendor-published or affiliate-style reviews, so confirm prices before committing.

Top picks by use case

• Duda (most established for agencies): Its strengths are a centralized dashboard to oversee all client sites, tiered user roles, and project tags, plus direct client access with custom permissions. It's the usual choice when you need full white-label delivery. The catch is cost: one listing puts the White Label plan at $199 a month, or $149 billed yearly, with 4 published sites, and each extra site at $17 a month. Also, the websites are not portable WordPress assets, so clients stay inside Duda.

• Wix Studio (best for design-flexible sites and client self-editing): It offers a centralized workspace with a 360-degree view of client projects, including billing, subscriptions, support tickets and reports. It suits agencies building visually flexible websites for small and midsize businesses that want to manage routine updates themselves.

• Webflow (best for design-led sites): Its agency workspace adds client payments, unlimited staging sites, three free client seats per site, and site-level roles and publishing permissions. Best for polished marketing sites, less so for high-volume cheap sites.

• 10Web or Appy Pie (lowest cost per site): 10Web's Agency Starter is $42.50 a month for 10 sites and Core is $80 a month for 20 sites, with yearly billing at 50% off. Appy Pie advertises paid plans starting at $18/month including full white-label branding, unlimited sites, client billing, and a reseller dashboard. Verify those limits before relying on them.

• We.Inc (flat-rate, AI-native, resale-focused): Its pricing is Lite $99/mo (25 client sites), Launch $499/mo (250), Scale $999/mo (1,000), with Stripe Connect billing. The vendor publishes this comparison, so weigh it accordingly.

• WordPress-based option (for ownership and portability): One guide argues that you can hand over real WordPress sites without locking every client into a proprietary website platform. That's the better choice if clients may leave or you need custom functionality, though it means more maintenance work for you.

How to choose

1. Resell or hand off? If you bill clients monthly for hosting and maintenance, a white-label platform with client billing fits. If you hand over sites once, a WordPress or Webflow workflow may work better.
2. Model cost at your real site count. Per-site pricing grows steadily; flat-rate tiers can be cheaper at scale. One comparison shows Duda at $301/mo at 10 sites, $981/mo at 50 sites and $2,681/mo at 150 sites on monthly billing, which is a useful sanity check against other options.
3. Check client-facing features. Look for client editing permissions, approval workflows, your own domain on the login portal, and whether billing runs through your own Stripe account.

If you tell me your rough site count, whether you resell monthly or hand off sites, and whether you need WordPress, I can narrow this to one or two recommendations.

For an agency managing multiple client sites, the "best" builder depends on your technical expertise, the complexity of your client needs, and your desired business model (e.g., whether you want to provide hosting as a managed service).

Here is a breakdown of the top platforms for 2026, categorized by how they serve agency needs.

1. The "Agency Standard" (Best for Creative Control)

• Webflow: Widely considered the standard for design-focused agencies.
  • Why it works: It offers a visual canvas that outputs clean, production-ready code. It includes robust collaboration tools like Shared Libraries (for design systems), roles and permissions, and staging sites.
  • Best for: Agencies that prioritize pixel-perfect designs, advanced animations, and high-quality, performant code without needing to write everything from scratch.
  • Trade-off: Steeper learning curve; higher per-site cost compared to entry-level builders.

2. The "All-in-One" Workspace (Best for Efficiency & Scale)

• Wix Studio: Built specifically as an agency workspace to solve the pain of juggling multiple logins.
  • Why it works: It features a centralized dashboard for managing all client sites, custom role-based permissions (for team members and clients), and standardized design systems. It also has strong AI-assisted tools for speeding up production.
  • Best for: Agencies that need to manage a large volume of sites efficiently and want a "one-stop shop" for design, hosting, and client management.

3. The Flexible/Reseller Option (Best for Recurring Revenue)

• Duda: Frequently cited as a top choice for agencies focusing on "client work" at scale.
  • Why it works: It was built with agencies in mind. It offers excellent white-labeling capabilities, allowing you to provide a branded editor experience to your clients. It is highly optimized for performance and is often used by agencies that bundle websites into larger marketing or SEO retainers.
  • Best for: Agencies looking to resell sites under their own brand, or those that want a reliable platform that handles the infrastructure so they can focus on client fulfillment.

4. The Power User’s Choice (Best for Maximum Freedom)

• WordPress: Still powers over 40% of the web.
  • Why it works: It offers total ownership of your data and site code. Through plugins like MainWP or hosting-specific dashboards (like those from managed WordPress hosts), you can manage updates, backups, and security for dozens of sites from one location.
  • Best for: SEO-heavy projects, complex B2B sites, or agencies that need custom functionality that proprietary builders cannot handle.
  • Trade-off: Higher maintenance (updates, security, plugin compatibility) and more responsibility for the agency.

Comparison Summary

Strategic Advice for Agencies

• Don't just pick one: Many successful agencies use a "tiered" approach. Use Webflow for high-end, bespoke creative projects that command premium pricing, and Wix Studio or Duda for local businesses or clients who need standardized, high-performing, easy-to-manage sites.
• Consider the "Exit" Question: Before committing to a proprietary platform (Webflow, Wix, Duda), ensure you are comfortable with the fact that these sites are generally not easily "migrated" away from their infrastructure. If a client eventually wants to move to a self-hosted custom solution, your only option may be a full rebuild.
• Focus on the Business Model: If you want to build a recurring revenue stream, prioritize platforms with strong white-labeling capabilities so that the client sees your brand, not the website builder's brand, in the editor.

If you’re looking for a website builder for an agency that builds sites for many clients, Duda is a strong fit—especially if you want to manage client access and offer a branded client experience. It has a central dashboard, granular client permissions, and optional white-label branding. Its Agency plan is listed at $52/month when billed annually, with four sites included; additional sites cost extra. Full white-label features are on higher-tier plans. ¹²³

Webflow is another good choice if you want more design flexibility and a clear client handoff. Its Agency Workspace is listed at $35/month billed yearly and includes unlimited staging sites, shared libraries, and client seats. Clients can also pay site-plan costs while a site remains in your workspace, and you can transfer sites to a client’s workspace later. ⁷⁹¹⁰

Quick recommendation: Choose Duda for streamlined client management and white-labeling; choose Webflow for custom design workflows and client-owned handoff. Prices and plan features can change, so check the providers’ pricing pages before committing. ²¹⁰
