SeldonFrame vs Kartra: Which Should You Choose? (2026)
500 contacts on the entry tier isn't a real local-business CRM. SeldonFrame gives every client an AI receptionist, website, CRM, and booking system for $29/mo flat, with no contact caps.
Kartra and SeldonFrame usually end up on the same shortlist for different reasons. Kartra is an all-in-one platform for creators and coaches selling courses, memberships, and video content, with contact-capped tiers. 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 Kartra if you're a creator or coach selling courses, memberships, or video content and want built-in affiliate management and a helpdesk alongside checkout. 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 comparison with that in mind — but we've tried to be specific about where Kartra genuinely wins below, not just where it doesn't.

How to switch from Kartra 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
Export your Kartra contacts to CSV and import them. SeldonFrame's booking calendar replaces any client-scheduling workflows you'd built around Kartra's checkout pages.
- 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 sell courses or memberships like Kartra?
No. SeldonFrame is built for local service businesses: an AI receptionist plus the website, CRM, and booking calendar behind it. It doesn't include course-hosting or membership-site tools.
Will I hit a contact cap on SeldonFrame like Kartra's tiers?
No. $29/mo is flat with no contact cap, at any tier.
Is SeldonFrame a good Kartra 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 Kartra's stacked pricing. See the full switching guide: /alternative-to-kartra.
How much does Kartra cost compared to SeldonFrame?
Kartra: Essentials $59/mo (500 contacts) / Starter $119 / Growth $229 / Pro $549 — contact caps every tier. 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.
See it built for YOUR business

No card. No call. Your data exports as JSON if you leave.
See it side by side before you decide
Paste a business's website and SeldonFrame builds the site, CRM, booking calendar and AI receptionist in about 3 minutes — free, before you sign up. Then it's $29/mo flat for unlimited workspaces.
