Agencies are in a gold rush right now. Every SMB client, from dentists to law firms, wants an AI agent on their website to capture leads and book appointments.

But for agencies, the problem isn’t building the bot. It is managing it.

Most AI platforms are built for single users. When you try to run 20, 50, or 100 client bots on them, you get hit with hidden taxes. You end up paying extra fees for custom domains, getting stuck with mandatory "Powered By" branding, or dealing with login nightmares.

If you are an agency owner looking to resell AI, here is the breakdown of the top 5 white label platforms in 2025.

1. Kuga (Best Overall for Agencies)

The "Agency Native" Platform

Most tools on this list started as B2C products and added an "Agency" plan later. Kuga was built for agencies from day one.

Instead of a messy list of bots, Kuga gives you a multi-tenant dashboard. You can manage 50 different clients from one screen. Each client gets their own isolated data, knowledge base, and branding.

Kuga also doesn’t charge you to unlock white labeling. Features like custom colors, unbranded emails, and agency branded dashboards come standard.

• Best Feature: Website Sync. You can turn a client’s entire website into a structured knowledge base in one click. It automatically separates Pricing, Services, and FAQs so the agent doesn't hallucinate.

• The Agency Edge: It integrates with Cal.com natively. This means your agents can actually book revenue for your clients, not just answer questions.

• Pricing: Starts at £19/mo per agent (approx. $24). No hidden fees for custom branding.

• Verdict: If you want to spin up and sell agents in under 15 minutes without eating into your margins, this is the one.

2. Stammer.ai (Best for Enterprise Volume)

The Premium Powerhouse

Stammer has made a name for itself as a heavy hitter in the white label space. It is a powerful tool with a strong focus on sub-accounts. This allows you to give your clients their own login credentials to manage their bots.

The platform is robust and offers detailed customization. However, it comes with a high barrier to entry. It is designed for agencies that already have a dozen paying clients ready to go, rather than those just starting out.

• Best Feature: Sub-account management. You can resell the software itself and effectively act as a SaaS distributor.

• The Agency Edge: Great for agencies who want their clients to log in and edit the bots themselves.

• Pricing: The Agency plan starts at $197/mo (includes 20 agents).

• Verdict: Excellent technology, but the $197 monthly starting price makes it a risky upfront cost for smaller agencies.

3. Chatbase (Best for Single, High-End Bots)

The Famous One

Chatbase is the big name in the room. It has incredible recognition and a very smooth UI. For a single business owner building one bot for themselves, it is arguably the best tool on the market.

However, the pricing model is painful for resellers. While the base subscription looks affordable, the extra fees add up fast. You often have to pay extra per month just to remove the "Powered by Chatbase" badge. You pay significantly more to connect a custom domain.

• Best Feature: The UI. It is incredibly polished and easy to use.

• The Agency Edge: High brand recognition means clients may have heard of it. This can actually be a downside if you are trying to white label.

• Pricing: Plans start around $19/mo, but adding a custom domain can cost an extra $59/mo per bot. Removing branding is another $39/mo.

• Verdict: Great tech, but the math often breaks for resellers. Paying roughly $100/mo per client for domains and branding leaves very little margin for the agency.

4. Dante AI (Best for Lead Forms & Personalities)

The Personality Specialist

Dante AI shines when you need highly customized personas. If your client wants a bot that speaks like a pirate or a specific brand mascot, Dante’s prompt engineering tools are top tier.

They also have strong features for lead generation forms embedded directly into the chat. However, the interface can get complex when managing dozens of distinct clients. Their credit based pricing system can also be unpredictable if a client goes viral.

• Best Feature: GPT-4 Vision support. Users can upload images for the bot to analyze. This is great for tech support.

• The Agency Edge: Strong lead form builder inside the chat.

• Pricing: Uses a complex credit system. Plans start around $29/mo, but high traffic agents will require expensive upgrades.

• Verdict: A strong contender if you need image analysis or specific personalities, but watch out for credit overages.

5. Voiceflow (Best for Developers)

The Logic Builder

Voiceflow is not really a chatbot builder. It is a visual coding platform. It allows you to build incredibly complex, branching logic trees. If your client needs a bot that connects to a weather API, updates a Salesforce record, and then sends a WhatsApp message, Voiceflow is the only choice.

But for 90% of SMB clients who just want to answer FAQs and book calls, Voiceflow is overkill. The learning curve is steep and maintenance is time consuming.

• Best Feature: The Canvas. You can visualize the entire conversation flow like a flowchart.

• The Agency Edge: You can build anything if you have the technical skills.

• Pricing: Free to start, but Pro features for client handoff quickly jump to $50/mo+ per editor.

• Verdict: Perfect for dev shops building complex products. Too slow and complex for marketing agencies.

Summary: Which one should you pick?

• If you are a Developer building complex apps: Voiceflow.

• If you have 50+ clients and a big budget: Stammer.ai.

• If you are an Agency who wants to sell Lead Capture Agents to SMBs with high margins and zero friction: Kuga.
