# SeldonFrame vs Stammer.ai: Which Should You Choose? (2026)

> 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.

Last updated: July 2026. HTML version: https://www.seldonframe.com/compare/seldonframe-vs-stammer-ai

## The short version

- **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

## SeldonFrame vs Stammer.ai: what you need to know

Stammer.ai and SeldonFrame usually end up on the same shortlist for different reasons. Stammer.ai is a white-label AI chat and voice agent platform. Agencies use it to resell agents under their own brand. SeldonFrame comes at the same problem from the other direction: one flat $29/mo workspace where the AI receptionist, website, CRM, booking calendar and intake forms arrive pre-wired — generated from a single conversation in about 3 minutes.

Choose Stammer if your offer is strictly agents-as-a-product and your clients' CRM, site, and calendar are already settled and staying put. SeldonFrame's case is the opposite one: when the outcome you're buying is answered calls, qualified leads and jobs booked into a CRM you own, that whole front office ships on day one and the economics stay flat as you grow. The rest of this page walks the differences row by row — pricing model, the AI receptionist, the business system behind it, whitelabel, and what switching actually takes.

We make SeldonFrame, so read this with that in mind — but we've tried to be specific about where Stammer.ai genuinely wins, not just where it doesn't.

## Where Stammer.ai wins

- Purpose-built for agency resale: unlimited client resale, agencies keep the markup
- Both chat AND voice agents, built in
- A real white-label dashboard at a price small agencies can afford ($197/mo)
- No cut taken on what agencies charge

The honest take: Choose Stammer if your offer is strictly agents-as-a-product and your clients' CRM, site, and calendar are already settled and staying put.

## Where SeldonFrame wins

- **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.

## Pros & cons, side by side

### SeldonFrame

- **Pro:** An AI receptionist that answers calls, SMS, and web chat — and books real jobs into a real calendar and CRM
- **Pro:** The whole front office included: multi-page website, CRM, booking, intake forms, review automation
- **Pro:** $29/mo flat with unlimited workspaces — bring your own key and AI and phone service run at raw provider cost
- **Pro:** Whitelabel built in: branded client portal, per-client workspaces, custom domains, one-click multi-client deploy

- **Pro:** Open core and portable — your agents are plain, editable skill files, and your data lives in your workspace
- **Con:** No funnel-builder or email-campaign suite — it's a front office, not a marketing automation platform
- **Con:** You bring your own key (Claude, ChatGPT, or Gemini, plus optional Twilio) — setup takes a few minutes
- **Con:** Newer platform — a smaller template library and community than decade-old incumbents
- **Con:** No native mobile app yet (the dashboard works fine on a phone browser)

### Stammer.ai

- **Pro:** A real white-label dashboard at a price small agencies can afford ($197/mo)
- **Pro:** No cut taken on what agencies charge

- **Con:** Usage fees (~$0.11–$0.17/min voice; per-message chat) stack on top of the subscription
- **Con:** No HIPAA option — regulated industries are out
- **Con:** A closed platform; some reports of struggling with complex queries

## 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.

## FAQ

**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.

**Is SeldonFrame a good Stammer.ai alternative?**

For most agencies and builders, yes — SeldonFrame replaces the AI-front-office job (answering, qualifying, booking, tracking in a CRM) at $29/mo flat instead of Stammer.ai's stacked pricing. See the full switching guide: /alternative-to-stammer-ai.

**How much does Stammer.ai cost compared to SeldonFrame?**

Stammer.ai: $49–$497/mo tiers + usage (~$0.11–$0.17/min voice; per-message chat). SeldonFrame: $29/mo flat, unlimited workspaces, first workspace free forever, with AI and telephony on your own keys at raw provider cost — no per-minute or per-credit meter.

**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.
