White-Label Isn’t a Logo Swap — It’s an Operating Model
A real white-label chatbot platform should let you control the client-facing brand across the widget, domain, emails, and admin surfaces, while also keeping each client isolated. If a vendor only lets you change colors and a logo, that is not enough for most agencies.
What to Verify Across These 7 Surfaces
Stammer AI — Best Overall for Agencies
Stammer AI is the best all-around option when you want a documented agency model, clear capacity limits, and BYOK support. It is the strongest starting point on documentation for agency structure plus model-provider control via BYOK.
Published Plan Structure

| Plan | Price | AI Agents | Sub-Accounts | Characters | BYOK |
|---|---|---|---|---|---|
| Agency | $197/mo | 20 | 20 | 20,000,000 | Yes |
| Full SaaS Mode | $497/mo | 100 | Included | 100,000,000 | Yes |
| Enterprise | From $2,500/mo | 1,000 | Included | 1,000,000,000 | Yes |
Why BYOK Matters
BYOK means Bring Your Own Key — in this case, your own OpenAI API key. That helps in three ways:
- Cost control — you can align spend with client accounts
- Vendor flexibility — you are less locked in
- Procurement comfort — some clients prefer their own key path
What Still Needs Trial Validation
Even with strong docs, verify in a trial: whether the widget is fully branded; whether emails show any vendor name; whether the admin UI leaks branding; whether custom domain handling is clean; whether error states expose the vendor; whether sub-accounts truly isolate data.
Kuga — Best for Per-Client Reseller Economics
If your business model is built around per-client agent pricing, Kuga is worth a close look. Its pricing page is explicit, and that alone makes it easier to model resale margins than many “contact sales” tools.
Kuga pricing, accessed 2026-06-12 — verify at kuga.ai/pricing
- \u00a319 to \u00a399/month per client agent
- Agencies typically retail agents for \u00a399 to \u00a3299/month
- Claims 100% white-label
- Mentions SMTP on pricing page
NIVA — Best for Fixed Messaging Limits
NIVA is interesting if you want a simpler commercial model with message caps and no usage-based billing language. It can be a good fit for small client deployments, pilot programs, or agencies that want a simple retail package.
NIVA homepage, accessed 2026-06-12 — verify at getniva.ai
- Freemium: $0/mo — 100 messages/month
- Basic: $39/mo billed $468/yr — 3,000 messages/month
- Claims No usage-based billing
Omni — Best If Channel Breadth Matters
Omni is the platform to look at when you care about broad deployment claims and channel coverage, but you should treat the vendor’s scale numbers and SLA language as vendor marketing until you validate them yourself.
Omni marketing page, accessed 2026-06-12 — vendor-stated claims, not independently verified
- 99.9% uptime SLA (vendor claim — verify SLA methodology, exclusions, service-credit terms)
- 12K+ active bots (vendor claim — not independently verified)
- 180+ countries (vendor claim — not independently verified)
- Channels mentioned: Slack, WhatsApp, Telegram, REST API routes

Frequently Asked Questions
What is the best white label AI chatbot platform in 2026?
Among platforms with clearly documented agency tiers, sub-accounts, and BYOK on-page, Stammer AI is the strongest all-around pick on a documented-plan basis. Its published plan structure shows Agency Plan at $197/mo with 20 AI Agents and 20 Client Sub-Accounts, Full SaaS Mode at $497/mo with 100 AI Agents, and Enterprise starting at $2,500/mo. That is unusually concrete for an agency buyer.
What does BYOK mean for a white label chatbot platform?
BYOK means Bring Your Own Key — specifically, Bring Your Own OpenAI API Key. This means you can use your own OpenAI API key rather than relying only on the platform’s shared usage model. It helps in three ways: cost control (you can align spend with client accounts), vendor flexibility (you are less locked in), and procurement comfort (some clients prefer their own key path). For agencies building a white-label business, BYOK can be the difference between a clean reseller model and a margin headache.
What surfaces should be verified for true white-label branding?
A real white-label platform should let you control the client-facing brand across: the branded chat widget on your own domain; email templates and sender identity; admin portal branding; error states and fallback pages; script/embed behavior and any vendor fingerprints; analytics/export naming; and client separation through sub-accounts or workspaces. A platform can look white-labeled on the front end and still be messy under the hood.
How does Kuga’s per-client agent pricing work for resellers?
Kuga’s pricing page states £19 to £99 per month per client agent. Agencies typically retail agents for £99 to £299/month according to Kuga’s pricing page. It claims 100% white-label and mentions SMTP. The per-client agent model is easy to explain to customers and the pricing ladder is simple enough to forecast. However, ‘100% white-label’ is a vendor claim until you verify it through a trial for widget, email, admin panel, and error-state leakage.
What is NIVA’s pricing model for white-label chatbots?
NIVA’s homepage shows a Freemium plan at $0/mo with 100 messages/month, and a Basic plan at $39/mo billed $468/yr with 3,000 messages/month. The page also says ‘No usage-based billing.’ No usage-based billing does not mean unlimited usage — NIVA still uses message limits, so your cost stays fixed but your volume is capped. White-label mechanics were not verified from cited sources in this review run.
How should I choose a white-label AI chatbot platform for my agency?
Choose based on the operational problem you are solving, not just the marketing headline. The best white label AI chatbot platform is the one that fits your client count, billing model, channel mix, and compliance needs. Use this shortcut: choose Stammer AI if you want the strongest documented agency structure and BYOK; choose Kuga if your business model is built around per-client agent pricing; choose NIVA if you want simple fixed-cost messaging plans; choose Omni if broad channel coverage matters most.
