Best Stammer.ai Alternative for Agencies & Builders
Stammer sells the agent layer — you still stitch the CRM, website and calendar per client. SeldonFrame is the whole whitelabel front office in one $29/mo platform.
Stammer.ai vs SeldonFrame: what you need to know
Most people looking for a Stammer.ai alternative hit the same wall: the agent is only one piece of the deliverable. 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 engagement still means stitching Stammer to a separate stack. Usage fees (roughly $0.11–$0.17/min voice, per-message chat) stack on top of the subscription, and regulated verticals are out — there's no HIPAA path.
That's not to say Stammer isn't impressive — it took the agency resale motion seriously before almost anyone: unlimited client resale, agencies keep their full markup, and a real white-label dashboard at a price small agencies can pay. If agents-as-a-product is your whole offer, it works. But agencies win local clients by delivering the outcome — answered calls, booked jobs, a working site — not a chatbot subscription.

Why agencies & builders switch from Stammer.ai
Sell the front office, not 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 meter eating your margin
Stammer bills per message and per minute on top of the subscription. SeldonFrame is BYOK — your keys, raw provider cost, margins you control.
The agent books real jobs
SeldonFrame's receptionist writes to the client's own calendar and CRM natively — no per-client integration between the agent platform and the business stack.
$29 flat vs $197 + usage
The whole whitelabel platform — unlimited client workspaces included — costs less than a sixth of the comparable Stammer tier before usage.

How to switch from Stammer.ai to SeldonFrame
- 1
Build the replacement free (3 minutes)
Paste the business's website into seldonframe.com — SeldonFrame extracts services, FAQs and business facts and generates 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 + FAQ (SeldonFrame generates 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 — ~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 auto-evals; talk to it, watch it book into the calendar, then publish. Point your domain when the site's ready.
- 5
Run both in parallel for a week
Keep the old tool alive while SeldonFrame answers the phones. Cancel when 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 brand, charge what you like, and keep it: there's no revenue share on client work you sell yourself.
Can I deploy one agent to many clients?
Yes — templates deploy per client in one click, and each deployment customizes greeting, voice, script and business info without forking the template.
How can SeldonFrame be $29/mo flat when competitors charge per minute or per credit?
Because you bring your own keys. Your agents run on your own AI provider key (Claude, ChatGPT or Gemini) and, for phone, your own Twilio account — so you pay providers at raw cost and SeldonFrame never resells tokens or minutes with a markup. The subscription is the platform, not a meter.
Do you take a cut of what I charge my clients?
SeldonFrame follows the same principle as Shopify: the platform is $29/mo flat, plus 2% on sales processed through SeldonFrame checkout, and 5% when you sell agents through the SeldonFrame marketplace. Client retainers you invoice outside SeldonFrame carry no fee at all.
How fast can I see it working?
Paste a business's website (or describe it in a sentence) and SeldonFrame builds the whole workspace — site, CRM, booking, intake and the AI agent — in about 3 minutes, free, before you ever sign up.
