The Best Retell AI Alternative for Agencies
Wave Runner is a white-label voice AI platform for agencies at $999/mo + $0.10/min with no-code setup, unlimited agents, and a multi-client dashboard. Retell AI is a developer-first platform with component pricing starting at $0.055/min base, landing at $0.13–$0.31/min all-in. Retell has no white-label and no multi-client management.
Retell AI crossed $50M ARR in 2025. That's a real number and it reflects real demand. It also tells you something about who the platform was built for. Engineers who need to assemble voice infrastructure fast love it. Agencies trying to resell it hit a wall.
The advertised rate is not what you pay. Once you add speech-to-text, a language model, text-to-speech, and telephony, the real cost is $0.13 to $0.31 per minute. Then there's no white-label, no consolidated client dashboard, and support that lives on Discord.
Here's where Retell fits and where it doesn't.
What Is Retell AI?
Retell AI is developer-first voice AI infrastructure. The pricing is component-based — you assemble the stack yourself from separate vendors.
Pricing
The $0.055/min headline is the infrastructure layer only. Real all-in cost:
- ●Retell infrastructure: $0.055/min
- ●Speech-to-text (Deepgram): ~$0.01/min
- ●LLM (GPT-4o): ~$0.03–$0.05/min
- ●Text-to-speech (ElevenLabs): ~$0.03–$0.10/min
- ●Telephony (Twilio): ~$0.01–$0.05/min
Total: $0.13–$0.31/min
Strengths
- ●4.8/5 on G2 (1,414+ reviews), 4.9/5 on Trustpilot
- ●SOC 2 Type II, HIPAA (BAA available), GDPR, and PCI — included on all plans
- ●~620ms average latency
- ●Well-documented SDK, active developer community
What's missing for agencies
- ●No white-label on any plan
- ●No multi-client dashboard — each client is a separate account
- ●No no-code path — every change requires a developer
- ●No per-client reporting from a single login

Pricing: The Component Stack Problem
Retell's $0.055/min is the infrastructure fee only. Every other component is billed separately by a different vendor.
| Component | Provider | Cost/min |
|---|---|---|
| Infrastructure | Retell | $0.055 |
| Speech-to-text | Deepgram | ~$0.010 |
| Language model | GPT-4o | ~$0.030–$0.050 |
| Text-to-speech | ElevenLabs | ~$0.030–$0.100 |
| Telephony | Twilio | ~$0.010–$0.050 |
| Total | $0.135–$0.265 |
Monthly cost at 10,000 minutes:
| Platform | Monthly cost | Notes |
|---|---|---|
| Wave Runner | $1,999 | $999 platform + $1,000 usage |
| Retell AI | $1,350–$2,650 | Usage only, no developer cost |
| Retell AI (with dev) | $6,350–$12,650 | Add $5k–$10k/mo developer |
Wave Runner's number doesn't change as you add clients. Retell's effective cost grows with every client because each one adds operational overhead.
The white-label gap
Without white-label, agencies can't resell voice AI at a margin. Clients see Retell's branding. That eliminates the revenue model entirely for most agencies.
Wave Runner's white-label is included on every plan. No add-on. No enterprise gate.
No Multi-Client Management
Retell has no agency management layer. Ten clients means ten separate Retell accounts — ten separate logins, ten separate billing setups, ten separate dashboards to check.
Wave Runner's dashboard shows all clients in one view. Per-client reporting, call recordings, and agent performance in one place. New clients are added in under an hour without a developer.
Compliance Trade-off
Retell's compliance coverage is genuinely strong. SOC 2 Type II, HIPAA (BAA available), GDPR, and PCI — all included on every plan, no enterprise gate.
Wave Runner's compliance certifications are in progress. If your client's legal team requires specific documentation before signing, Retell has an edge here.
For most agencies, that's not the deciding factor. If it is for yours, verify before committing.
When Retell AI Might Fit
- ●You have a dedicated developer. The SDK is well-documented and engineers can build fast.
- ●You need compliance documentation now. SOC 2 II, HIPAA, GDPR, and PCI are included and ready to present.
- ●You're managing 1-3 technical clients. At low volume and client count, component economics can work before overhead becomes painful.
- ●You're building a custom product. If voice AI is a feature inside something you're building, Retell gives more architectural control.
But agencies reselling voice AI across 5+ clients hit the ceiling fast: no white-label, no consolidated dashboard, developer dependency for every change.
Where Wave Runner Wins
- ●Full custom branding included — no white-label add-on, no enterprise gate
- ●One invoice regardless of how many clients you run
- ●Deploy new clients in under an hour without a developer
- ●Single dashboard across all clients with per-client reporting
- ●Platform fee falls per client as you scale
- ●Private Slack channel and dedicated account manager, not a Discord server
- ●No developer required for any part of the workflow
FAQ
Is Wave Runner cheaper than Retell AI?
At low volume (under 5,000 min/mo), Retell's raw usage fees can be lower than Wave Runner's $999/mo platform fee. But once you add developer cost (which Retell requires), white-label tools, and the management overhead of multiple accounts, Wave Runner is consistently cheaper for agencies running 5+ clients.
Does Retell AI have a white-label option?
No. Retell AI has no white-label on any plan. Third-party tools like VoiceAIWrapper and Voicerr.ai offer white-label wrappers on top of Retell, but those add another vendor, another cost, and another potential point of failure.
Can I use Retell AI without a developer?
Not really. Retell is API-first. Agent configuration, integrations, and most changes require code. Some visual tooling exists in the dashboard, but any real customization or client-specific setup requires developer involvement.
How does latency compare?
Retell averages ~620ms, which is faster than Wave Runner's sub-800ms target. In practice, the difference is not perceptible to callers. Both are within the range where conversations feel natural. Premium LLMs on Retell can push response times to 1.5–2.5 seconds, which does affect call quality.
What if I'm already using Retell AI?
Migration is straightforward. Agent prompts, knowledge base content, and phone numbers all transfer. The main work is reconfiguring integrations. Wave Runner's onboarding team handles the setup. Most agencies are live with existing clients within a few days of switching.
The Bottom Line
Retell AI is solid infrastructure for developer teams building custom voice applications. The compliance coverage is real, the SDK is well-documented, and the community is active.
For agencies running multiple clients and reselling voice AI as a service, Retell creates problems that its per-minute rate doesn't solve. No white-label means no resale margin. No multi-client dashboard means manual operational overhead at every client. Developer dependency means every client change is a dev ticket.
Wave Runner is built for the agency model: white-label included, one flat invoice, no-code deployment, and a platform fee that gets more efficient with every client you add.
