Retell AI alternatives
The 8 closest alternatives to Retell AI, which starts at $0.07/mo. Each one below does roughly the same job from a different angle.
Why people move off Retell AI
- Less flexibility than Vapi: you can bring your own LLM but voice processing is Retell's own
- $0.07/min standard rate is higher than Vapi's $0.05/min before component costs
- Premium tier at $0.25/min adds up fast at serious call volume
- Younger company than some alternatives, so enterprise procurement processes can be slower
Worth weighing against what it does well: sub-800ms latency is fast enough that most callers don't notice the processing pause
