Try KallyAI for $1Why Users Are Leaving Synthflow
Synthflow made a significant pricing change that displaced many of their SMB customers:
- Starter plan removed — The $29/mo plan that attracted small businesses is gone. The cheapest option is now the Pro plan at $450/mo
- 15x price increase — Going from $29/mo to $450/mo is a 15x jump with no affordable middle ground
- Enterprise-only positioning — Synthflow now targets mid-market and enterprise customers with plans at $450/mo (Pro), $900/mo (Growth), and $1,400/mo (Agency)
- Trustpilot complaints — Users report feeling caught in a "bait-and-switch" after building on the affordable tier
- No migration path — Small businesses who built workflows on Synthflow have no affordable way to stay
If you were on Synthflow's Starter plan or considering their platform, you need an alternative that won't price you out.

What KallyAI Offers Synthflow Users
Affordable from day one
KallyAI's Starter plan is $19/mo — not $450. You can try it for $1 with a money-back guarantee. No enterprise sales calls, no annual commitments, no minimum spend.
No flow builder required
Synthflow requires building voice agent workflows with their visual builder. KallyAI works differently: describe what you need in plain language, and the AI handles the rest. "Call my dentist and book a cleaning for next week" — done.
More than just voice agents
Synthflow focuses on voice agents for customer service workflows. KallyAI handles the full admin workflow: phone calls, follow-up emails, vendor research, and multi-step coordination. One task can span multiple channels.
Built for individuals and small businesses
Synthflow moved upmarket to serve agencies and enterprises. KallyAI is built for the users they left behind: solopreneurs, freelancers, small business owners, and individuals who need AI to handle calls and admin tasks.
Plan approval before action
Before making any call, KallyAI shows you the plan and waits for approval. You see who will be called, what will be said, and what information will be gathered. Synthflow agents run automatically once configured.
What Synthflow Does Better
Synthflow is a strong product for its intended audience. Here is where it excels over KallyAI:
- High-volume concurrent calls — 25-200+ concurrent calls for contact centers and agencies handling large call volumes
- No-code visual builder — Drag-and-drop workflow builder for complex, repeatable voice agent flows
- CRM and tool integrations — 12+ integrations including HubSpot, Salesforce, GoHighLevel, and Zapier
- Multilingual voice agents — Support for multiple languages in a single agent configuration
- White-label options — Agency plan includes white-labeling capabilities for resellers
If you need enterprise-scale voice automation with CRM integrations and high concurrency, Synthflow may still be the right choice — at the new price point. But if you are a small business or individual who needs affordable AI calling, KallyAI is the better fit.
Other Synthflow Alternatives
If you are evaluating all your options after Synthflow's pricing change, here are other platforms to consider:
| Platform | Best For | Starting Price | Key Limitation |
|---|---|---|---|
| KallyAI | Personal use, SMBs, solopreneurs | $1 trial / $19/mo | US-focused (expanding) |
| Bland.ai | Developers building custom voice agents | Pay-per-minute ($0.07-0.14/min) | Requires coding, no end-user product |
| Lindy.ai | Workflow automation with phone features | Free (400 credits) / $49.99/mo | Phone calls expensive (20 credits/min + $0.19/min) |
| Air.ai | Outbound sales teams | Contact sales | Sales-focused, not for personal or inbound use |
| VAPI | Developers building voice AI products | Pay-per-minute | API-only, requires development resources |
For SMBs and solopreneurs displaced by Synthflow's pricing change, KallyAI is the most accessible option — no coding, no enterprise pricing, no complex setup.
