## 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.

## Who should use Stammer.ai vs SeldonFrame

Choose Stammer.ai if:
1. Agents-as-a-product is your entire offer
2. Your clients' CRM/site/calendar stack is settled and staying
3. You want a mature whitelabel chat-agent dashboard today

Choose SeldonFrame if:
1. You'd rather sell the whole front office ($300–800/mo retail) than a chatbot subscription
2. You want the agent writing to a CRM and calendar the client owns
3. You want BYOK margins instead of platform usage rates
4. $29 flat vs $197 + usage changes your per-client math

To be fair: Choose Stammer if your offer is strictly agents-as-a-product and your clients' CRM, site and calendar stack is already settled and staying.

## 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.

## FAQ

**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.
