Comparison
Vapi Retell AI
Side-by-side: pricing, features, integrations. Pick the one that fits.
Short version: Consider Retell if you want more of the phone-agent stack managed in one place. Its published pay-as-you-go range is $0.07–$0.31 per minute, depending on configuration. Vapi charges $0.05 per minute for hosting, with model, transcription, voice and telephony costs added separately. Choose between them by building the same agent and pricing the same calls, not by comparing those two starting numbers.

Bottom line
Budget for the whole call. At 1,000 minutes, Vapi's hosting fee is $50 before provider costs. Retell's published range gives $70–$310 at the selected rate; check its calculator for what your voice, model, telephony and add-ons include. This is arithmetic from listed prices, not a measured bill.
Pick Retell if its managed setup covers your booking, support or lead-qualification workflow. Pick Vapi if choosing providers and writing custom integrations matter more. Neither is guaranteed to be cheaper, faster to launch or lower-latency for your setup.
Run a small trial with the same call script, phone region and model. Compare completed calls, delays and the actual invoice before committing.
