Best Stammer.ai Alternative for Agencies & Builders
Stammer sells you the agent — you still have to stitch together the CRM, website, and calendar for each client. SeldonFrame is the whole whitelabel front office in one $29/mo platform.

Most people looking for a Stammer.ai alternative hit the same wall: the agent is only one piece of what you need to deliver. The $197/mo agency tier covers whitelabel chat and voice agents, but there's no CRM, no website builder, and no booking calendar behind them. So every client still means connecting Stammer to a separate stack yourself. Usage fees (roughly $0.11–$0.17/min for voice, plus per-message chat) stack on top of the subscription, and regulated industries are out — there's no HIPAA option.
That said, Stammer is impressive. It took agency reselling seriously before almost anyone else: unlimited client resale, agencies keep their full markup, and a real white-label dashboard at a price small agencies can afford. If agents are your whole offer, it works well. But agencies win local clients by delivering results — answered calls, booked jobs, a working site — not just a chatbot subscription.
- Stammer.ai pricing: $49–$497/mo tiers + usage (~$0.11–$0.17/min voice; per-message chat)
- SeldonFrame pricing: $29/mo flat, unlimited workspaces, first workspace free forever
- Pick Stammer.ai if: Agents-as-a-product is your entire offer
- Pick SeldonFrame if: You'd rather sell the whole front office ($300–800/mo retail) than a chatbot subscription

Why agencies & builders switch from Stammer.ai
Sell the front office, not just a chatbot
With SeldonFrame, each client gets a branded website, CRM, booking calendar, intake, and the agent — one deliverable worth $300–800/mo retail, from one platform.
No usage fees eating your margin
Stammer bills per message and per minute on top of the subscription. SeldonFrame runs on your own keys at raw provider cost, so you control your own margin.
The agent books real jobs
SeldonFrame's receptionist writes straight to the client's own calendar and CRM — no separate integration project between the agent and the rest of the business.
$29 flat vs $197 plus usage
The whole whitelabel platform — unlimited client workspaces included — costs less than a sixth of the comparable Stammer tier, before usage fees.

How to switch from Stammer.ai to SeldonFrame
- 1
Build the replacement free (3 minutes)
Paste the business's website into seldonframe.com. SeldonFrame pulls out services, FAQs, and business facts and builds the workspace: site, CRM, booking calendar, intake, and the AI agent. No account needed until you claim it.
- 2
Bring what matters over
Recreate each client agent from its prompt and FAQ (SeldonFrame builds most of it from the client's website), and re-point any embedded chat widgets to the new embed snippet.
- 3
Connect your keys and number
Add your AI key (Claude, ChatGPT, or Gemini — about 30 seconds) and, for phone, connect your Twilio number so calls and missed-call text-back run at carrier cost.
- 4
Test the agent, then go live
Every agent ships with automatic tests. Talk to it, watch it book into the calendar, then publish. Point your domain over when the site's ready.
- 5
Run both in parallel for a week
Keep the old tool running while SeldonFrame answers the phones. Cancel it once the CRM shows the bookings landing — cancel-anytime on both sides means zero risk.
Frequently asked questions
Does SeldonFrame let me resell like Stammer does?
Yes. Deploy agents (and whole front offices) to unlimited client workspaces under your own brand, charge what you like, and keep it — there's no cut taken on client work you sell yourself.
Can I deploy one agent to many clients?
Yes. Templates deploy per client in one click, and each one can have its own greeting, voice, script, and business info without touching the original template.
How can SeldonFrame be $29/mo flat when competitors charge per minute or per credit?
Because you use your own keys. Your agents run on your own AI key (Claude, ChatGPT or Gemini) and, for phone, your own Twilio account. You pay the providers at raw cost. SeldonFrame never marks up tokens or minutes. You pay for the platform, not a meter.
Do you take a cut of what I charge my clients?
SeldonFrame works like Shopify: $29/mo flat, plus 2% on sales made through SeldonFrame checkout, plus 5% when you sell agents on the SeldonFrame marketplace. Client retainers you bill outside SeldonFrame cost nothing extra.
How fast can I see it working?
Paste in a business's website (or just describe it in a sentence). SeldonFrame builds the whole workspace — site, CRM, booking, intake, and the AI agent — in about 3 minutes. It's free, and you don't need to sign up first.
