## The short version

- **Synthflow AI pricing:** Usage-based from ~**$0.08–$0.09/min** + LLM & telephony **add-on**s; whitelabel listed at **$2,000/mo** or enterprise contracts from ~**$30k/yr**
- **SeldonFrame pricing:** **$29/mo** **flat**, **unlimited workspaces**, first workspace **free forever**

## SeldonFrame vs Synthflow AI: what you need to know

Synthflow AI and SeldonFrame usually end up on the same shortlist for different reasons. Synthflow AI is a no-code voice-agent builder for phone receptionists and appointment booking. 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 Synthflow if you want a mature template library for pure phone agents and your clients already have their CRM and calendar sorted out. 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 Synthflow AI genuinely wins, not just where it doesn't.

## Full feature & pricing comparison

| Feature | SeldonFrame | Synthflow AI |
|---|---|---|
| Best for | Agencies & builders running AI front offices for clients | Non-technical teams launching phone agents from templates |
| Pricing model | From **$29/mo** **flat** — **unlimited workspaces** (agency whitelabel from **$99/mo**) | Usage-based from ~**$0.08–$0.09/min** + LLM & telephony **add-on**s; whitelabel listed at **$2,000/mo** or enterprise contracts from ~**$30k/yr** |
| AI receptionist (calls, SMS, chat) | Native — AI receptionist answers, qualifies & books across voice, SMS & web chat | Yes — no-code voice agents with booking flows |
| Website, CRM & booking behind the agent | Included — multi-page website, CRM, booking calendar, intake forms, review requests in every workspace | None — voice agent only; CRM, website and calendar live elsewhere |
| Whitelabel & client workspaces | Included — whitelabel client portal, per-client workspaces, custom domains, one-click multi-client deploy | Yes, but as a **$2,000/mo** **add-on** or enterprise bundle |
| AI usage costs | BYOK — bring your own AI (and Twilio) keys and pay providers at raw cost, zero markup | Per-minute, with engine/LLM/telephony pieces stacking |
| Sell / resell what you build | Built in — publish agents to the marketplace or rent them via MCP (**5%** marketplace fee) | Yes — via the (paid) whitelabel program |

## Where Synthflow AI wins

- Genuinely no-code, with useful templates for specific industries
- A real agency setup: sub-accounts, client pricing controls
- Bundled per-minute pricing is simpler than raw component math
- Managed or bring-your-own-Twilio telephony

The honest take: Choose Synthflow if you want a mature template library for pure phone agents and your clients already have their CRM and calendar sorted out.

## Where SeldonFrame wins

- **Whitelabel at $29, not $2,000** — SeldonFrame's agency layer — client workspaces, branded portal, one-click multi-client deploy — is part of the flat $29/mo plan. It's not a four-figure add-on.
- **Costs you can actually predict** — Per-minute pricing that shifts with model and telephony choice makes quoting clients a guessing game. Bring your own key and your AI and Twilio costs are raw provider rates you can see and cap.
- **The agent comes with its business system** — Synthflow books appointments into someone else's calendar stack. SeldonFrame's receptionist books into the client's own workspace — calendar, CRM, website, and intake all included.
- **One conversation replaces flow-building** — Describe the business and SeldonFrame builds the agent AND the workspace around it in about 3 minutes — no drag-and-drop flow building for each client.

## 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:** Build it free before you sign up — paste a URL, get a working workspace in about 3 minutes
- **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)

### Synthflow AI

- **Pro:** Genuinely no-code, with useful templates for specific industries
- **Pro:** A real agency setup: sub-accounts, client pricing controls
- **Pro:** Bundled per-minute pricing is simpler than raw component math
- **Pro:** Managed or bring-your-own-Twilio telephony
- **Con:** Whitelabel is listed at $2,000/mo (or ~$30k/yr enterprise contracts)
- **Con:** Per-minute costs stack (engine + LLM + telephony) — hard to quote for busy clients
- **Con:** Cost is the #1 complaint in public reviews
- **Con:** Voice-only — the CRM, site, and calendar live elsewhere

## How to switch from Synthflow 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 your Synthflow flows as plain-language skills (most receptionist flows come down to: greet, qualify, check availability, book, take message) and re-point your Twilio number.
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 have vertical templates like Synthflow?**

Yes. An agent library covers the common local-business jobs — receptionist, speed-to-lead, review requests, and more. Each one deploys per client, and you can change the greeting, voice, and script for each.

**What do voice minutes cost on SeldonFrame?**

You connect your own Twilio number and AI key, so calls cost whatever the providers charge. SeldonFrame doesn't meter or mark up minutes on the $29/mo plan.

**Is SeldonFrame a good Synthflow 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 Synthflow AI's stacked pricing. See the full switching guide: /alternative-to-synthflow.

**How much does Synthflow AI cost compared to SeldonFrame?**

Synthflow AI: Usage-based from ~$0.08–$0.09/min + LLM & telephony add-ons; whitelabel listed at $2,000/mo or enterprise contracts from ~$30k/yr. 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.
