12 Best White-Label Chatbot Platforms for Agencies in 2026: Compared

What "white-label" actually means

Reselling an AI chatbot only works if the client never sees the vendor. A real white-label product clears four hard requirements, and a lot of platforms on the usual "best white-label chatbot" lists clear none of them:

• Full brand removal, not just a "Powered by" badge on the widget, but the dashboard, the login screen, and transactional emails.
• Your own domain, the client logs into app.youragency.com, not the vendor's URL.
• Client sub-accounts, a multi-tenant console where each client is their own workspace that you manage as your product.
• Your own pricing, you set plans and bill clients directly, keeping the markup.

By that bar, three big names on this list, Tidio, Landbot and Botpress, are widget-only and not true reseller products. We kept them in, clearly labelled, because they show up everywhere and you should know why they don't qualify.

The reviews

Ordered for this blog's audience, EU agencies that need GDPR-compliant hosting. If that's not you, the "Which should you pick?" section below routes you to the right alternative.

1. WebChatAgent: GDPR-first, German-hosted Editor's pick for EU agencies

Full disclosure: this is our platform, so weigh this accordingly, we kept the numbers verifiable. WebChatAgent is hosted in Germany on every tier, ships a ready-to-sign DPA (AV-Vertrag), and trains no models on customer data. Branding is invisible down to the login screen and transactional emails, the custom domain points via DNS, and white-label starts at just €29/mo (Solo, one client bot), scaling to €99 Starter, €199 Growth and €399 Scale as you add client bots and message volume. Here's the part no other entry on this list can match: it pairs that white-label reselling with a genuinely full feature set, multi-LLM choice (Gemini, OpenAI, Grok, Mistral), MCP tool-calling, WhatsApp, a WordPress plugin, RAG over your own documents, lead capture and WCAG 2.2 AA accessibility. The full-featured incumbents (Intercom, Zendesk) don't white-label at all, and the dedicated white-label tools here are far thinner on features. Where it loses: the message quota is an org-wide pool shared across all client bots, so one high-traffic client can burn it; the custom-domain setup is a manual DNS A-record rather than a polished managed CNAME flow; direct Stripe client-billing is a €499 one-time add-on; and it's a smaller brand than the US incumbents. But for an EU agency whose clients ask where the data lives, German hosting plus a DPA on every tier answers that better than any US-built platform here, and at €29 it's also the cheapest genuine white-label entry on this list.

Best for: EU/German agencies and web studios reselling to healthcare, legal or finance clients.

2. Stammer AI: the most complete reseller engine

Built ground-up as a reseller SaaS. Custom domain, full debrand and per-client usage wallets are core features, not an upsell, and they start at the $197/mo Agency tier, which also covers both chat and voice agents. Higher tiers (Full SaaS $497/mo, Enterprise from ~$2,500/mo) add scale. The catch for European agencies: Stammer is US-built, and the EU data-residency claim floating around aggregators isn't confirmed on Stammer's own pages, so don't promise it to regulated clients. Pricing has also moved repeatedly, confirm current numbers.

Best for: US-market agencies reselling chat + voice as their own SaaS.

3. Robofy: the cheapest multi-license entry

A real reseller admin with client sub-accounts, zero revenue share, and a low multi-license entry: $97/mo for the Accelerator tier (10 client licenses), up to $149/mo Enterprise for unlimited licenses, with 33% off annually. Robofy's page states EU (Ireland) data residency and offers a self-hosted .NET option, unusual at this price. Watch two things: the lower tiers give you a Robofy-hosted sub-domain, not your own custom domain (that's gated to Enterprise), and answer quality leans hard on how well you structure the knowledge base.

Best for: Budget-conscious web/WordPress agencies that want lots of client licenses cheaply.

4. BotPenguin: full rebrand, strong WhatsApp, opaque pricing

A genuine agency product: rebrand the platform, the bots and the help docs so clients never see BotPenguin, with unlimited client sub-accounts, 100% revenue retention and local-currency billing. Multichannel is a strength (WhatsApp BSP, Telegram, Messenger, web). The friction is commercial, not technical: only the entry "Baby" tier shows a public number, and it conflicts between BotPenguin's own pages (~$1,200 vs ~$1,500/year), while the top three tiers are contact-sales, and entry billing is annual-only. EU server region appears to be a paid add-on, not standard.

Best for: Agencies wanting low-cost, fast-to-launch multichannel resale and fine with annual billing.

5. FastBots: true white-label with a 5-brand ceiling

A branded client-login platform with custom domain at $333/mo on annual billing ($399 monthly), multichannel deployment (web, WhatsApp, Telegram, Instagram, Slack) and 15+ models you can mix. Two real limits: a hard cap of 5 client brands before you must jump to Enterprise, and US-centric infrastructure (AWS, Supabase, Fly.io) with no confirmed EU residency. The white-label is a re-skinned FastBots rather than a multi-tenant codebase you control.

Best for: Small-to-mid agencies reselling a no-code RAG bot to a handful of clients.

6. ConvoCore: branded voice + chat, messy pricing

One of the few here that leads with voice alongside chat: full debrand, custom domain, unlimited sub-accounts and a selectable EU (Frankfurt) region, sold as a white-label add-on from roughly $200/mo on top of a base plan, with usage metered on top. The honest caveat: the base fee is cited inconsistently across ConvoCore's pages ($200 vs $220), and per-seat surcharges plus usage make total cost harder to model than a flat agency tier.

Best for: Agencies wanting a branded voice + chat agent and comfortable with usage-based math.

7. CustomGPT.ai: compliance-grade RAG, priced for it

The strongest compliance posture in the field, SOC 2 Type II, GDPR, DPA, genuine per-client data isolation, and excellent RAG over a client's documents. The trade-off is cost and gating: self-serve branding removal starts at a steep $449/mo (Premium, annual), and real white-label with a custom domain effectively needs Enterprise or the Solutions Partner program, neither of which publishes agency pricing. Premium is also capped at 5 agents, which is tight for an agency managing many clients.

Best for: Compliance-sensitive, document-heavy support bots where accuracy and certifications matter most.

8. Botsify: broad channels, thin transparency

Genuine reseller rights (debrand, custom domain, your own pricing) and the widest channel spread here, web, WhatsApp, Messenger, Instagram, Telegram, SMS, Slack, plus a bring-your-own-key option to control LLM cost. Two weak spots: the agency-tier price is demo-gated (the live page exposes only a $149/mo plan, and the ~$199 agency figure comes from search snippets, not a confirmed price string), and the GDPR posture is thin, sub-processors are named but there's no stated EU residency or DPA.

Best for: Agencies that need a multichannel WhatsApp/Messenger/Instagram backend and will negotiate terms.

9. Voiceflow: great builder, white-label gated to Enterprise

A mature, well-liked visual agent builder with an explicit multi-client agency offering and branding removal on Business-tier seats. But full product-wide white-label is Enterprise-only, the public pricing page is now quote-gated, and custom-domain hosting of the builder isn't confirmed. Layered pricing (base + per-editor seats + usage credits) makes client margins hard to predict.

Best for: Conversation-design teams that want a polished builder and will talk to sales.

10. Botpress: powerful builder, not a reseller product

Worth being blunt: Botpress is a superb developer-grade builder, but its "white-label" is widget-only (badge and colours). There's no rebranded dashboard, no custom platform domain, and no client sub-account model under your brand; the partner track is co-sell/referral, not reselling. Widget debranding starts at $89/mo (Plus). Build client bots with it, don't expect to resell it as your own SaaS.

Best for: Technical teams delivering custom bots as a service, not a productised resale.

11. Landbot: genuine EU hosting, no reseller tier

Best-in-class visual/WhatsApp builder with real EU data residency (Google Cloud, Belgium) and a downloadable DPA, but no white-label dashboard, no custom app domain, and no agency tier. Each client needs their own paid account, so reselling doesn't scale economically; the only partner option is a 20% affiliate commission. Branding removal on the widget starts at €100/mo (Pro).

Best for: Single brands wanting a polished WhatsApp/web bot under their own widget.

12. Tidio: polished, but referral not resale

A mature live chat plus the Lyro AI agent, strong on Shopify/e-commerce. For agencies, though, it's the weakest "white-label" here: you can strip the widget badge (a +$16.67/mo Growth add-on, or bundled into Plus at $749/mo), but there's no rebranded dashboard, no custom domain, and no client console. The agency program is a referral/revenue-share deal (up to 25%), not a rebrandable platform.

Best for: SMB/Shopify stores wanting one polished brand, or agencies happy to earn a referral cut.

Which should you pick?

There's no single winner, only a best fit per situation. Match the platform to your clients and your channel mix:

• EU or German agency, regulated clients (healthcare, legal, finance) → WebChatAgent. German hosting and a ready DPA on every tier answer the "where does the data live?" question that kills US-built platforms in these deals.
• US agency wanting the most complete reseller engine → Stammer AI. Chat + voice, full debrand from $197/mo, if EU residency isn't a requirement.
• Tightest budget, just getting started → WebChatAgent at €29/mo (EU-hosted white-label, one client bot), or Robofy at $97/mo for 10 client licenses.
• WhatsApp-first, many small clients → BotPenguin for multichannel breadth and 100% revenue retention.
• Voice agents under your brand → ConvoCore.
• Compliance and RAG accuracy above all → CustomGPT.ai (budget for Enterprise).

The agency margin math: what you actually keep

White-label only pays if the platform fee is a flat cost you mark up. Most genuine resellers here (Robofy, BotPenguin, ConvoCore, Stammer) take zero revenue share, so 100% of the markup is yours. Here is the real number, using one scenario: 10 client bots, each billed at €59/mo, is €590/mo of recurring revenue. What each platform leaves in your pocket after its fee:

USD fees converted at roughly $1 = €0.92, so verify live prices. The number that quietly eats margin is the usage model: shared message pools (WebChatAgent, FastBots, ConvoCore) and per-credit metering (Botsify, Robofy) erode profit when a high-traffic client burns the quota. Cap usage per sub-account, or build that risk into your client plans.

GDPR and EU data residency: the deal-breaker most lists ignore

If your clients are European, and especially if they're in regulated sectors, hosting location is not a nice-to-have, it's the first question procurement asks. The honest landscape: WebChatAgent hosts in Germany on every tier with a ready DPA and no LLM training on customer data, the clearest EU-residency story here. Robofy (EU/Ireland) and ConvoCore (selectable EU/Frankfurt) state EU regions as vendor self-statements, confirm the DPA directly. Landbot genuinely hosts in the EU (Belgium) but isn't a reseller product. Most US-built platforms (Stammer, FastBots, Botsify, CustomGPT) will sign a DPA but do not guarantee EU-only residency by default. Verify before you pitch a regulated client.

Frequently asked questions

What counts as a real white-label chatbot platform?

Four hard requirements: vendor branding removed everywhere (not just the widget badge, but the dashboard, login screen and transactional emails), your own custom domain, client sub-accounts you manage as your own product, and the ability to set your own prices and bill clients. Platforms that only hide a "Powered by" badge on the widget fail this test, by that bar, Tidio, Landbot and Botpress are widget-only, not true reseller products, even though they appear on many "white-label" lists.

What's the cheapest way for a new agency to start reselling?

WebChatAgent is the cheapest genuine white-label entry at €29/mo (Solo, one client bot, EU-hosted), scaling to €99 Starter for multiple bots. Robofy is the cheapest multi-license option at $97/mo (10 client licenses, zero revenue share). Watch the fine print elsewhere: Stammer lists a $49 Starter but real reseller features begin at its $197 Agency tier, and BotPenguin's entry looks cheap (~$1,200–1,500/yr) but is annual-only and conflicts across its own pages.

How do agencies actually make money reselling these?

You pay a fixed platform fee and charge clients a markup, keeping the difference. Most platforms here (Robofy, BotPenguin, ConvoCore, Stammer) advertise zero revenue share, so 100% of the markup is yours. Watch the usage model: shared message pools and per-credit metering can erode margin if a high-traffic client burns the quota, so cap or price usage per sub-account.

Is there a GDPR-compliant, EU-hosted white-label option?

WebChatAgent hosts in Germany on every tier with a ready-to-sign DPA and no LLM training on customer data, the clearest EU-residency story in this list. Robofy states an EU (Ireland) region and ConvoCore offers a selectable EU (Frankfurt) region; both are vendor self-statements, so confirm the DPA directly. Most US-built platforms sign a DPA but don't guarantee EU-only residency by default.

Can I white-label ChatGPT or another LLM directly?

No. You white-label the platform wrapped around the model, not the model itself. These tools run RAG over your client's website and documents on top of GPT, Claude or Gemini and put your brand on the interface. Several (Stammer's higher tiers, Botsify, FastBots) let you bring your own OpenAI key so you pay model cost directly instead of the vendor's usage markup.

White-label vs a reseller program: what's the difference?

A white-label platform lets you rebrand the product and resell it as your own under your domain and pricing. A reseller or affiliate program (Tidio, Landbot, Botpress) just pays you a commission for referring clients to the vendor's branded product, your client still sees the vendor. Only the former lets you own the relationship and the margin.

Bottom line

There's no universal best, there's a best for your clients. Stammer is the most complete reseller engine if EU data residency isn't a hard requirement. Robofy is the cheapest credible entry. The widget-only names (Tidio, Landbot, Botpress) are fine products but not reseller platforms, don't pick them for white-label work. And if you sell to European clients who will ask where their data lives, WebChatAgent answers that with German hosting and a DPA on every tier, from €29/mo on your own domain. Start free and put it on your own brand.
