What is Retell AI?

Retell AI is a developer-focused platform for building and deploying AI-powered phone agents—capable of both inbound and outbound calls—at scale. Designed to support complex workflows and high-concurrency scenarios, Retell AI is best suited for companies with engineering resources who want granular control over call flows, voice selection, LLM integration, and compliance options.

The platform stands out for its real-time voice streaming (sub-second latency), “bring your own carrier” flexibility, advanced interruption handling, and compatibility with leading LLMs like GPT-4o and Claude. Retell’s modular setup and API-first design make it a strong fit for tech-forward teams or those running high-volume, programmatic call campaigns.

Retell AI Pricing Structure

Retell AI adopts a pay-as-you-go pricing model, allowing businesses to tailor costs based on their chosen voice engines, language models, call volumes, and additional features.

Core Pay-As-You-Go Pricing:

Free Trial:

• $10 in free credits (about 60 minutes of calls)
• 20 concurrent calls
• 10 free Knowledge Bases
• Discord and Email support

Enterprise Plan:

• Discounted pricing at higher volumes (as low as $0.05/min for voice)
• Managed agent setup and scaling by Retell’s team
• Dedicated support (private Slack)
• Higher concurrency and Knowledge Base limits
• Early access to beta features

Cost in Practice: The true per-minute rate typically falls between $0.13 and $0.31, depending on the voice engine, LLM, telephony, and knowledge base usage. The more advanced the setup (better voices, more powerful LLMs), the higher your effective cost.

Example: If you run 2,000 minutes per month using ElevenLabs voice ($0.07), Claude 3.5 LLM ($0.06), and Retell’s telephony ($0.01), your total would be about $0.14/min, or $280/month. This can scale down with volume discounts or up with more expensive LLMs or added features.

Retell AI vs. the Competition: Prices, Features, and Reviews Compared

Retell AI’s pricing is modular and transparent, but requires users to track multiple cost layers (voice, model, telephony, features). This is flexible for engineering-driven teams but may create budgeting complexity for non-technical buyers or those seeking a turnkey solution.

Retell AI: Key Strengths

• Granular control: Choose your voice, model, carrier, and integrations
• Low latency: ~800ms, with barge-in/interruption handling
• Compliance: SOC 2, HIPAA, GDPR (but not ISO 27001 or RBAC)
• Integrations: Twilio, Telnyx, SIP, custom APIs
• Developer focus: Build via API, SDK, or CLI

Potential Limitations

• No drag-and-drop builder: All prompt logic and flows are managed via code/API
• No voice cloning: Unlike some rivals, custom voice is not included
• Higher setup complexity: Non-technical teams may struggle without engineering support
• No live sandbox or visual flow testing

User reviews praise the voice quality and flexibility, but note the need for technical skills to leverage Retell’s full power. Support is generally responsive for enterprise customers, but changelogs and live ticketing are limited for standard users.

Exploring Alternatives to Retell AI

Retell AI is best for companies that want full control and have the engineering resources to build and iterate on conversational flows. For teams seeking a plug-and-play solution, a no-code environment, or predictable billing, several alternatives may offer better fit:

• Synthflow: All-in-one pricing, no-code builder, and bundled features
• Goodcall: Subscription-based, unlimited minutes, per-user pricing
• Vapi: Developer-first, modular stack, but technical setup required
• Thoughtly: No-code, SMB-oriented, affordable entry but less mature

Best Competitor – Pod AI

Pod AI (the team behind this blog) is purpose-built for companies who want to deploy phone AI agents with no technical setup required, flat monthly pricing, and full access to every feature out of the box. Pod AI’s bundled model means you get:

• Unlimited access to premium voices, transcription, and analytics
• Full CRM integrations (HubSpot, Salesforce, Zapier, etc.)
• Built-in compliance features (call recording, transcript storage, opt-out management)
• All essential automations (appointment scheduling, lead capture, post-call follow-ups)
• Simple, transparent billing (no hidden or variable fees)

Why choose Pod AI over Retell AI? While Retell AI gives engineering teams maximum flexibility, Pod AI is designed for immediate deployment—no coding, no per-feature fees, and no surprises at the end of the month. For most teams focused on scaling support, sales, or outbound calling, Pod AI’s all-inclusive approach means fewer headaches and more value.

Conclusion

Retell AI’s pricing offers impressive flexibility and control for companies able to manage their own integrations, call flows, and feature stack. However, the modular, per-minute structure requires careful monitoring to avoid cost surprises—especially as call volumes and feature needs grow.

For teams looking for simplicity, ease of use, and reliable monthly costs, all-in-one platforms like Pod AI or Synthflow are a strong alternative. They bundle every feature (voices, minutes, analytics, integrations) for one predictable fee, helping companies focus on customer engagement, not invoice management.
