Synthflow Pricing 2025: Decoding the Costs and Comparing Alternatives
A complete breakdown of Synthflow’s pricing in 2025, including its tiers, hidden costs, and how it stacks up against Pod AI — the best alternative for businesses seeking predictable, scalable, and enterprise-ready AI phone agents.
What is Synthflow?
Synthflow is a no-code voice AI platform that enables businesses to create automated agents for inbound and outbound calls. The system integrates with CRMs, supports custom workflows, and offers modular APIs for building more advanced call flows.
While it promises scalability and quick deployment, Synthflow’s pricing is structured in tiers with additional per-minute charges beyond the included allotments. This makes it important for businesses to understand the real cost at different usage levels — especially if call volumes fluctuate.
Synthflow Pricing Structure
Synthflow uses a subscription-based pricing model with five tiers: Starter, Pro, Growth, Agency, and Enterprise. Each tier includes bundled minutes, concurrent calls, and workflow limits, with overage charges applied per minute when businesses exceed the included call time.
| Plan | Price/Month | Minutes Included | Overage Rate | Concurrent Calls | Workflows / Subaccounts | Key Features |
|---|---|---|---|---|---|---|
| **Starter** | $29 | 50 mins | N/A | 5 | Unlimited | Voice API, real-time booking, human transfer, community support |
| **Pro** | $375 | 2,000 mins | $0.13/min | 25 | 8,000 | Workflow builder, team access, support via ticketing |
| **Growth** | $750 | 4,000 mins | $0.12/min | 50 | 42,000 + 25 subaccounts | Rebilling, access to new features |
| **Agency** | $1,250 | 6,000 mins | $0.12/min | 80 | 100,000 + unlimited subs | White-label platform, onboarding, Slack support |
| **Enterprise** | Custom | Volume-based | As low as $0.08/min | 200+ | Custom | SIP trunking, custom integrations, guaranteed SLA, compliance (SOC2, HIPAA, GDPR) |
Example Monthly Costs
- Pro Plan (2,000 mins): $375 base + $130 for 1,000 extra minutes ($0.13/min) = $505 total.
- Growth Plan (4,000 mins): $750 base + $240 for 2,000 extra minutes ($0.12/min) = $990 total.
- Agency Plan (6,000 mins): $1,250 base + $480 for 4,000 extra minutes ($0.12/min) = $1,730 total.
For businesses scaling past included minutes, Synthflow’s pricing grows quickly — often making it unpredictable for budgeting.

Strengths of Synthflow
- No-code interface: Quick deployment without engineering.
- Workflow flexibility: Thousands of workflows supported at higher tiers.
- Scalability: Enterprise plan can handle 200+ concurrent calls.

Customer Sentiment
Reviews of Synthflow are mixed. Users praise its ease of setup and workflow builder, but some note challenges with call quality and unpredictable billing when scaling.
Exploring Alternatives to Synthflow
While Synthflow is strong for teams experimenting with no-code AI voice agents, its unpredictable costs and technical limitations make it less ideal for businesses looking for enterprise-ready reliability.
Alternatives worth exploring include:
- PolyAI: Enterprise-focused, but requires long deployment timelines and $150K+ budgets.
- Retell AI: Strong modular system, but costs can climb above $1,000/month for moderate call volumes.
- Goodcall: Subscription-based but tied to “unique customer” limits, creating hidden fees.
Among these, Pod AI stands out as the best alternative.
Best Competitor – Pod AI
Pod AI is a 24/7 AI phone agent platform designed to replace or augment customer support, sales, and scheduling calls. Unlike Synthflow’s unpredictable overage model, Pod provides transparent, stable pricing with all features included.
Why Pod is Better than Synthflow
- Predictable Pricing – Pod’s plans bundle features and minutes together without hidden overages.
- Faster Deployment – Pod can launch AI agents in days, not weeks, thanks to its optimized setup.
- Superior Voice Quality – Leveraging advanced voice models, Pod delivers sub-500ms latency and natural-sounding voices.
- Compliance Ready – SOC2, HIPAA, and GDPR compliance baked in for enterprise use.
- Integrated Analytics – Pod provides post-call summaries, sentiment tracking, and CRM sync by default.
Example Comparison
| Feature | Synthflow | Pod AI |
|---|---|---|
| Price Structure | $375–$1,250/mo + per-minute overages | Transparent fixed monthly pricing |
| Deployment Speed | 3–6 weeks | Days |
| Voice Latency | ~600–800ms | <500ms |
| CRM Integration | Zapier & limited APIs | Native integrations (Salesforce, HubSpot, etc.) |
| Compliance | Enterprise only | All plans |
| Best For | SMBs testing AI agents | Companies of all sizes scaling real customer conversations |
Conclusion
Synthflow offers a flexible no-code option with workflow customization and scaling potential. However, its per-minute overages and gated enterprise features make it risky for businesses seeking predictable budgets.
By contrast, Pod AI delivers the same scalability and richer features at transparent, stable pricing — with enterprise compliance, faster deployment, and superior customer experience.
For teams looking to adopt voice AI in 2025, Pod stands out as the best alternative to Synthflow.
