White-Label AI Agents: 8 Platforms for Agencies in 2026

The pitch never changes. Put your logo on an AI agent, sell it to a client as your own product, charge a monthly retainer, keep the difference. Every page ranking for this search will happily tell you what the client pays. Almost none of them tells you what lands on your own card at the end of the month.

That missing half is the entire business. A retainer is revenue. Margin is what survives the platform fee, the model usage and the hours you spend keeping twelve clients' agents alive.

I build on the other side of this trade. Gravity is an AI agent platform where independent builders publish agents and get paid every time one runs, so the cost of a run and what is left over is the number I look at most weeks.

So this post does two jobs. It maps eight platforms agencies actually use to ship agents under their own brand, grouped by what you are really reselling. Then it builds the table the rest of this category skips: what your own bill looks like at 5, 10 and 25 clients, and which line item quietly eats the profit.

One note on prices before you scroll. I quote a dollar figure for exactly one product here, my own, because I can point you at the page it comes from. Plan pages in this category move often enough that a number printed in October 2026 is a liability by the time you read it. Every section links the vendor's plan page instead, and the margin model runs on whatever number you find there.

How I compared them

Five questions, asked of each platform. They decide your margin more than any feature grid will.

• Who does the work after the sale? You, a contractor on your payroll, or somebody who already built the agent and keeps it running.
• What actually carries your brand? There is a long distance between hiding a vendor logo on a chat widget and running the whole dashboard on your domain, with your name on the login screen and on the emails it sends.
• What is the billing unit? Flat agency plan, per client sub-account, per seat, or metered usage. That one line explains most of the margin surprises in this category.
• Who picks up the phone when a client's agent breaks on a Monday? On most of this list, you do.
• Can you leave? Prompts, flows and client history rarely export cleanly, and a platform switch with twelve live clients will cost you a quarter.

What this comparison is built on: each vendor's own public positioning and documentation for how the product is structured and how it bills. I have not run a bake-off between them, and I have not used all eight with live clients, so you will find no performance claims here. The comparison is structural, because structure is the part that survives a pricing change.

Quick comparison

I read these vendors' own pricing pages on 15 September 2026. Where a page publishes a self-serve rate I have put it in the billing column; where it does not, the column gives the billing shape instead, because that is the part the margin model actually needs. Voiceflow and Synthflow publish plan structures rather than one agency rate, so I have not invented a starting number for either. Open the plan page linked in each section and put your own figure into the margin model below.

1. Gravity: best when you would rather earn per run than carry a platform bill

This is my product, so weigh what follows accordingly. It sits first because it inverts the deal every other platform on this page offers you.

The standard white-label arrangement puts you in the middle of the sandwich. You pay the platform, you bill the client, and you absorb everything in between: the setup, the model spend, the breakages, the renewal conversation, the month a client's systems change and nothing works. Your margin is whatever survives all of that.

Gravity runs the other way round. A builder publishes an agent, Gravity carries the infrastructure, the distribution and the billing, and the builder earns 21.27% of every run that agent does, rising to 25% at the top tier. No per client platform fee exists, because the people running your agent are Gravity's customers rather than yours.

What you give up is the invoice. You do not set the end price, you do not own the billing relationship, and your name is not on the contract. What you get is a cost sheet with no platform line on it and no Monday morning support queue. The builder onboarding guide walks through publishing, and the complete marketplace guide covers the model itself.

Why the marketplace model changes your margin

Reselling pays you once a month per client and charges you once a month per client, so your income and your workload grow at the same rate. Publishing pays you on every run, for everyone who runs it, and charges you nothing per head. The second one compounds with usage rather than with your headcount.

Best for

Builders and agencies who would rather own an asset that earns per run than a retainer they have to service every month.

Pricing

First agent free, no card. Then Autopilot at $20 a month worldwide, ₹1,999 a month in India, with a lot of usage included. India also has Minipilot at ₹399 a month with a smaller allowance. Buy more usage if you run out. As of September 2026.

Builder share

21.27% of every run, up to 25% at the top tier.

Verdict

The only option here where your cost per client is zero, and the only one where somebody else answers the support ticket.

2. GoHighLevel: best if your agency already runs on one dashboard

GoHighLevel was built for agencies long before the AI wave, and the shape of the product shows it. Client work happens inside sub-accounts. Snapshots clone an entire setup into a new client in minutes. The AI features arrived on top of an agency structure that was already load bearing.

Its reseller tier is the part that matters for this list. On the higher plan you run the platform on your own domain with your branding and sell it to clients as your software at your price, and the AI features ride along inside that wrapper.

The cost is scope. You are adopting an entire agency operating system, so the CRM, the funnels, the scheduler and the pipelines arrive whether you asked for them or not. Agencies already living in it get the AI for very little extra tooling. Agencies who are not are buying a great deal of software in order to white label one agent.

The sub-account is the unit you resell

Everything is priced and organised around the client sub-account, which makes per client margin unusually easy to forecast: one account, one number, multiply by your client count. Read the current tiers on the GoHighLevel pricing page and note which tier unlocks reselling before you model anything.

Best for an established agency with ten or more clients already in the platform. If you are not running GoHighLevel today, price the whole suite rather than the AI features before you compare it with anything else on this page.

3. Stammer.ai: best when the reseller relationship is the product

Stammer is one of the few platforms here designed from day one to be somebody else's product. The pitch is direct: build AI agents, put them on your domain under your logo, set your own prices, sell them to clients as your platform.

For an agency that means the packaging work is already done. You spend no time styling a widget so it looks less like a vendor's. The surface a client touches, the login, the dashboard, the agent itself, is meant to read as yours.

The trade shows up in what you can build. A platform tuned for resale optimises for a repeatable agent you spin up per client, which is exactly right for a productised offer and constraining the first time a client wants something genuinely bespoke.

So what is left for you to build?

Mostly the offer. Which client problem the agent solves, what onboarding looks like, what you charge, who answers when it misbehaves. That is real work, and it is the work that separates one reseller from the twenty others using the same platform.

Best for

Agencies selling a productised AI offer to many similar clients, where the same agent shape fits client after client.

How it bills

Plans sized by the number of agents and client accounts you run. Current tiers are on stammer.ai.

What carries your brand

Your domain, your logo, your pricing to the client.

Verdict

The shortest distance between deciding to resell AI agents and having a client-facing product with your name on it.

4. Botpress: best when your clients need real engineering underneath

Botpress is a builder's platform. Visual flows, yes, but with code nodes, an SDK, version control habits and the sort of integration depth that survives contact with a client's actual stack.

Botpress sells no white-label tier. White labelling here falls out of how you ship: you embed the agent inside your client's product or your own wrapper, and Botpress stays out of sight underneath. Agencies with a developer on staff tend to prefer that, because nothing about the deliverable is constrained by a reseller dashboard.

Billing is usage shaped, which is the honest model and the harder one to quote against. A chatty month costs more than a quiet one. If you sell a fixed monthly retainer on top of a variable cost base, you are carrying that variance yourself, so price for the bad month rather than the average.

Where the engineering bill shows up

Not in the platform invoice. It arrives as developer hours on the first integration for every new client, and that is the line deciding whether client six is profitable or merely busy. Check the current usage rates on the Botpress pricing page and model them against your busiest client.

Best for

Agencies with a developer, selling to clients whose systems are messy enough that a reseller platform would have to say no.

How it bills

Usage shaped, tied to conversations and model calls, with a free tier to prototype on.

What carries your brand

Everything the client sees, because you built the surface it sits in.

Verdict

The most capable option on this page and the one with the largest hidden labour cost.

5. Voiceflow: best when the client wants to see the flow before it ships

Voiceflow grew up in conversation design, and its centre of gravity is still the canvas where a team maps what an agent says and does. For agency work the useful property is that the canvas is legible to a non-technical client.

That matters more than it sounds. A large share of agency friction is approval: the client cannot picture what they bought until it is live, and then they want it changed. A design surface they can read converts that into a review meeting instead of a rebuild.

What ships to the client's users carries the client's brand. What you build in is a workspace, priced by seats and usage, and that sits on your side of the ledger. Seats have a way of multiplying as the client list grows, so count the seats you will need at fifteen clients rather than at three.

Clients approve what they can see

Put the canvas in the room during scoping and one round of revisions becomes one conversation. Across a year of client work that is a real saving, and it lands in the hours column, which is where your margin actually lives.

Current seat and usage tiers are on the Voiceflow pricing page. Model it at your target client count before you sign the annual plan.

6. Pickaxe: best for selling one narrow AI tool on your own domain

Pickaxe is for the small, sharp thing. A single-purpose AI tool with a form, a prompt behind it, a paywall if you want one, and your branding around it. You assemble it without code and embed it on your site or your client's.

Agencies use it for lead magnets and micro products rather than for agent teams. A property firm's rental yield calculator. A clinic's pre-visit questionnaire that writes the summary for the doctor. Something a client understands in ten seconds and can show their board.

Branding sits behind a paid tier

Removing vendor branding and running on your own domain are tier-gated on most tools in this bracket, Pickaxe included, so work out which tier you actually need before you quote a client a price. The plan page lists what each tier unlocks.

It suits a productised micro offer and it will disappoint a client who wants an agent running real operations. As a first sale it is hard to beat: something small, branded and live this week is often what earns you the larger engagement three months later.

7. Chatbase: fastest first deliverable on this list

Point Chatbase at a client's site, docs and help centre, and there is a support agent answering questions the same afternoon. Nothing else here gets from signed contract to something the client can click that quickly.

The white labelling is modest and adequate. Vendor branding comes off on paid plans, the widget takes the client's colours, and it lives on their domain as an embed. Nobody will mistake it for custom software, and for a support deflection deliverable nobody needs to.

Its ceiling is the same thing as its appeal. It answers questions well and it does not run operations, so the retainer it supports is smaller than one attached to an agent that files, books or chases things on the client's behalf.

What deflection has to beat

A support agent earns its retainer by removing tickets a human would otherwise answer. Ask the client what a ticket costs them today and how many arrive in a month. If they cannot tell you, that is your first billable piece of work, and it is worth more to them than the widget.

8. Synthflow: best when the client's front door is a phone number

A lot of local businesses lose more money to unanswered calls than to anything happening on their website. Clinics, garages, trades, restaurants, letting agents. Synthflow builds voice agents that answer, qualify, book and route, and it courts agencies deliberately with white label arrangements.

Voice carries a cost line the rest of this page does not have. Telephony minutes are metered, and the meter runs while the caller talks, so a busy month arrives with a bill attached. Price the retainer on call volume rather than on a flat guess, and check the current per minute rates on the Synthflow pricing page.

Voice fails in public

A chat agent that stumbles loses a lead quietly. A voice agent that stumbles does it to a person mid sentence, and the client hears about it from their own customer the same day. Budget more supervision hours here than anywhere else on this list, especially in month one.

Best for

Clients whose first customer contact is a phone call, in categories where a missed call is a lost job.

How it bills

A plan fee plus metered voice minutes, so your cost moves with your client's call volume.

What carries your brand

White label options aimed at agencies; confirm what the tier you are buying actually covers.

Verdict

The highest perceived value per client on this page, and the highest supervision load to go with it.

The margin math nobody publishes

Here is the hole in every article ranking for this term. They will tell you an agency can charge a monthly retainer for an AI agent. They will not show you the other side of the ledger, so you cannot work out what is left. The numbers below are inputs rather than findings. I picked round ones so you can swap in your own and have an answer in five minutes.

The three cost shapes

Every platform on this page bills in one of three shapes, and the shape decides how your costs behave as you add clients.

Example inputs, not vendor prices. Replace the second column with the number on your platform's plan page and the rest is arithmetic. Gravity's 21.27% builder share is from the builders page, September 2026.

Read the last column first. A flat agency plan gets cheaper per client every time you sign one, which is why platforms billing that way are the easiest to scale on. Per account and metered shapes stay flat or drift upward, so your twenty-fifth client costs roughly what your first one did, and growth buys you no relief at all.

The line that actually eats it

Now take one client on a $500 monthly retainer and follow them through three different months.

Example inputs, costing your time at $50 an hour. The bad month assumes the client changed a system, the agent broke twice and somebody rebuilt an integration.

The platform bill is the smallest number in every column. Your hours are the largest, and they are the only line that moves by a factor of six between a good month and a bad one. The entire sales conversation in this category is about the line that does not decide the outcome.

Then scale it. At twenty-five clients a bad month is rarely one client; it is the four or five who all changed something in the same fortnight, and they do not queue politely. Agencies do not stall here because the platform got expensive. They stall because client eighteen signed while three earlier clients were mid crisis.

So the number to track is margin per hour of your attention. Margin per client flatters you right up until the month it stops. Marketplace splits compared runs the same question across platforms that pay a share instead of charging a fee.

Set the retainer after you know the floor

Work out your bad month cost first, then price so a bad month still clears your floor. If that number is higher than the client will pay, narrow the agent until it fits. A smaller agent that never breaks is worth more to both of you than a broad one you subsidise with unpaid hours.

Which one should you choose?

Start from what you are actually selling. That decides the platform far more reliably than a feature grid does.

If your client work already lives in GoHighLevel, the AI answer is almost certainly GoHighLevel. Adding a second platform to save a subscription is how agencies end up with two systems and a reconciliation problem.

When the offer is productised and repeats across similar clients, Stammer.ai is the shortest path. It was built for exactly that shape, so your first month goes into selling rather than into fighting the packaging.

With a developer on the team and clients whose systems are a mess, take Botpress. You will do more work, and you will be able to say yes to requests the reseller platforms have to decline.

Voiceflow earns its place when approval cycles are the bottleneck rather than build time. Showing a client the flow in week one is cheaper than rebuilding it in week six.

For a first small paid deliverable, Pickaxe or Chatbase. One sells a tool, the other deflects tickets, and either can be live inside a week.

Clients who live on the phone are a Synthflow conversation, with more supervision budgeted than you think you need. Voice is the one place on this list where a bad week reaches the client's customers directly.

My own bias, stated plainly. If the agent you built solves a problem that is not unique to one client, reselling it twelve times is the slow version of the idea. Publish it once, let everyone who needs it run it, and take 21.27% of every run with no platform bill and no support queue. That is Gravity, and how to monetize AI agents lays out the wider set of options if a marketplace is not where you want to end up.

Agencies with a specialism have a shortcut. AI agents for SEO agencies and AI agents for marketing agencies list the deliverables worth turning into a product before you go platform shopping.
