Our verdict: Retell AI

Best quality-to-performance ratio for SMBs with a developer or integrator. Free credit eases evaluation. Avoid if usage is very light; additional costs weigh on small volumes.

Our verdict: Vapi

Ideal for startups and tech teams wanting full control over their voice agent. Avoid without an in-house developer: the learning curve is steep and hidden costs pile up quickly.
