Duda vs Simvoly: which white-label builder suits your agency?

The short answer

Choose Duda if your agency builds and runs sites for clients, cares most about design quality and control over what clients can touch, and expects to grow into hundreds of sites. It is also the safer bet if you need an API.

Choose Simvoly if you want the lowest white-label entry price, your clients sell through funnels with upsells, or you want clients to sign up, pick a template and pay you a subscription without you setting up each account.

Neither has a deep sales CRM. If you want AI to draft every client site, plus a CRM and funnels under your brand, there is a third option near the end. We make it, so read that section with that in mind.

Duda and Simvoly at a glance

The main differences, on annual billing in US dollars:

What it costs at 10 and 25 client sites

The two price lists work differently, so the base fee alone tells you little.

• Duda charges per account. The White Label plan includes 4 sites, and each extra site costs $168 a year (about $14 a month) or $17 month to month. A store is an add-on per site: Standard is $7 a month for up to 100 products, Advanced $20 for 1,000. Annual plans are charged up front.
• Simvoly charges a white-label base fee, then a monthly fee per client project. That fee depends on the project level and your white-label tier. On WL Basic a simple Starter-level site costs $8 and a Premium-level project, which on Simvoly's plan list includes funnels and unlimited store products, costs $25. On WL Advanced those fall to $7 and $22, and on WL Ultimate to $5 and $15.

A rough monthly bill on annual billing, where each store has under 100 products:

For 10 sites, Duda is $149, plus 6 extra sites at $14, plus 3 Standard stores at $7. Simvoly is $59, plus 7 Starter projects at $8, plus 3 Premium projects at $25. We have not subtracted Simvoly's included projects, because its pricing page and white-label page describe them differently, so treat its figures as a ceiling.

What stands out:

• Simvoly is cheaper for brochure sites, mainly because of its lower base fee.
• For store clients the gap closes. With Duda's Standard store, each store site costs about $21, slightly less than on Simvoly's Basic and Advanced tiers. Above 100 products, Duda's Advanced store pushes that to about $34, while Simvoly's Premium level lists unlimited products.
• Simvoly's WL Ultimate only pays off at scale. Against WL Basic it saves $3 per simple site and $10 per store or funnel site, so you need roughly 37 store projects, or more than 120 simple ones, to cover the extra $370 a month.

Duda's Agency plan ($52 a month, 4 sites) has the same per-site pricing, but Duda keeps full white-labelling for its White Label and Custom plans. Our guide to Duda pricing for agencies goes deeper. Simvoly offers a free trial without a card and a 14-day money-back guarantee on annual plans, so it is cheaper to test.

Client editing and the white-label experience

This is where the two feel most different, because they assume different ways of working with clients.

Duda is built for done-for-you agencies. You decide, per client and per site, what they can change. A content-only permission lets a client edit text and images without adding or removing sections, so they cannot break your layout. You can also grant full editing, open the content library, or lock specific data collections. On the White Label plan the editor carries your logo, colours and domain. Clients get a branded support portal and branded emails with their site stats, and they can pay you one-off or recurring charges inside the platform.

Simvoly is built for a do-it-yourself, SaaS-style model. You add your logo, domain and custom CSS or JavaScript, and platform skins restyle the builder itself. Its best feature here is self-serve sign-up: a customer registers on your branded platform, picks one of your templates, customises it and subscribes to one of your plans through your payment processor, without your help. WL Advanced and Ultimate add an unbranded video academy for client training and an affiliate programme.

If clients mostly ask you to make changes, Duda gives you more control. If you want to sell a branded website product to people who build their own sites, Simvoly's sign-up flow fits better.

AI site building and templates

Duda has moved faster here. In July 2026 it announced improved AI site generation: you describe the site in a conversation, can upload a client brief or sales call transcript, and the AI builds from scratch or from a template. Its AI tools also write pages, sections and blog posts, generate SEO titles, meta descriptions and image alt text, and build custom widgets inside the editor. The announcement does not say which plans include each feature, so check before buying. Duda's professionally designed templates have long been one of its strengths.

Simvoly's white-label pages mention one AI feature: a text assistant in the editor for writing copy. You can build your own templates for websites, funnels, pages, popups and emails, which matters in the self-serve model because your templates are where customers start. If AI drafting would save you hours per site, Duda is clearly ahead.

Ecommerce for client stores

Duda sells its store as an add-on per site. Standard ($7 a month on annual billing) covers 100 products, Advanced ($20) covers 1,000 and Elite ($45) covers 20,000. Duda takes no transaction fee, though your payment provider still charges its own. Automated tax (through Avalara) and shipping labels (through Easyship) are built in, with monthly usage limits. Bookings come with the store plans, and charging for appointments needs Advanced or Elite.

Simvoly handles most product types and weekly, monthly or yearly subscriptions. It also covers variants with their own price, SKU and stock, shipping rules and regional tax rules, and you can connect one or more payment processors. Some older user reviews say it suits smaller catalogues better than large ones.

For a big catalogue, automated tax or a lot of shipping, Duda's store is more complete. For coaches, course sellers and subscription offers sold through funnels, Simvoly fits better. If the store is the whole business, a dedicated platform such as Shopify (from $29 a month) may suit that client better than either.

Funnels

This is a clear win for Simvoly. Its funnel builder handles multi-step sales funnels with upsells, downsells, order bumps and one-click upsells, plus A/B testing to compare two versions of a page. WL Basic includes a funnel allowance (its pricing page lists 10), and the higher tiers list unlimited funnels. Quizzes, appointment booking and online communities sit in the same platform, which suits coaches and course sellers.

Duda has no dedicated funnel builder. You can build landing pages and forms like any other page, but a checkout funnel with upsells usually means paying for a separate tool. If funnels are central to what you sell, our roundup of white-label funnel builders covers the wider field.

CRM and marketing depth

Duda does not include a CRM. Form submissions go to email, or to HubSpot, Salesforce, Zoho CRM and others through Zapier and similar integrations. That is fine if clients already use a CRM, but it is one more tool to set up and support.

Simvoly includes a CRM with unlimited contacts, activity history, custom properties, tags and stored form submissions. It also has an email builder, segments, automation flows, and SMS, WhatsApp and voice messages. Marketing subscribers are capped per plan, with more available as a paid add-on. Its CRM page does not describe deal pipelines, tasks, lead scoring or invoicing, and review sites call the CRM basic. It is good for building and emailing a list, but weaker for tracking sales.

If clients need a real sales pipeline, you will need more than either tool offers. GoHighLevel (from $97 a month) is the usual pick for deep CRM and automation, at a higher price and with a steeper learning curve.

API access and scale

If you run a platform, such as a hosting company or a SaaS product, and want to create sites for your users automatically, Duda is the proven choice. It has a REST API with single sign-on, and its pricing table puts API access on the Custom plan, which is priced on request and includes unlimited API calls.

Simvoly's white-label pages focus on the branded platform and self-serve sign-up, and they do not advertise a partner API. If you need one, ask Simvoly before committing.

A third option: WebNewBiz

Agencies often compare Duda and Simvoly because they want fast site building, funnels and a CRM in one branded login. Duda is strongest on the first. Simvoly covers the second and part of the third. WebNewBiz tries to cover all three, with AI doing the first draft.

• AI drafting: describe the client's business in plain language and the AI drafts the whole site (pages, layout and copy). Changes are made by chatting with the AI Copilot.
• AI CRM and funnels: the CRM reads and scores leads and handles deals, tasks, bookings and invoices that chase themselves. The funnel builder drafts a landing page, opt-in and thank-you page from a description of the offer, or starts from one of 26 templates, and opt-ins land in the CRM.
• White-label: your name, logo and colours on a dashboard at your own domain (such as app.youragency.com), with a branded login page, emails and invoice PDFs. You create client accounts with plan limits, and you can log in as a client to do the work or let them self-serve.
• Your prices: sell your own packages from your own storefront page, paid into your own Stripe or PayPal account. Platforms can use a partner REST API with single sign-on and webhooks.

The honest limits: WebNewBiz is younger and smaller than Duda, with a much smaller app ecosystem. Agency pricing is not published, so you have to talk to us. Our funnel builder focuses on landing, opt-in and thank-you pages, so Simvoly is stronger for checkout funnels that rely on upsells. The AI draft still needs each client's own photos and facts.

How to choose: a short checklist

1. Count your sites. List how many client sites you have now and expect to have in a year, and how many need a store. Then run both price lists.
2. Decide who edits. If you make most changes, Duda's permissions protect your work. If clients build their own sites, Simvoly's self-serve sign-up is made for that.
3. Check what clients sell. Funnels with upsells point to Simvoly. Large catalogues and automated tax point to Duda.
4. Decide where leads go. With Duda you add a CRM, and Simvoly's CRM is basic. Include the cost of any extra tool in the comparison.
5. Check whether you need an API. If you do, talk to Duda about its Custom plan first.
6. Test with one real client. Build an actual client site on a trial, including a client login, before moving everyone.
7. Plan the exit. Ask how content and domains move if you leave. Switching builders usually means rebuilding layouts.

Quick answers

Is Duda or Simvoly cheaper for agencies?

Simvoly is usually cheaper. Its white-label plans start at $59 a month on annual billing, against $149 for Duda's White Label plan. At 25 client sites with 8 small stores we estimate about $395 a month on Simvoly WL Basic and about $499 on Duda, although Duda can be slightly cheaper per store site.

Which has better funnels, Duda or Simvoly?

Simvoly. It has a dedicated funnel builder with upsells, downsells, order bumps and A/B testing. Duda has no dedicated funnel builder, so checkout funnels usually need a separate tool.

Does Duda have a built-in CRM?

No. Duda sends form submissions to email or to outside CRMs such as HubSpot, Salesforce or Zoho through integrations. Simvoly includes a basic contact CRM with email automation.

Which is better if clients edit their own sites?

Duda gives you detailed permissions for each site, such as content-only editing, so clients cannot break your layouts. Simvoly is better if you want clients to sign up, build and pay on their own through your branded platform.

Do Duda and Simvoly offer an API?

Duda offers a REST API with single sign-on on its Custom plan, priced on request. Simvoly does not advertise a partner API on its white-label pages, so ask them directly.

Is there a white-label builder with AI drafting, a CRM and funnels together?

WebNewBiz drafts each client site with AI and includes an AI CRM and funnel builder under your brand, on your own domain and at your own prices. It is younger and smaller than Duda, and agency pricing is not published, so you need to contact the team.
