Retell.ai vs Bland AI Comparison (2025)

Retell.ai
Starting at $0.07 – 0.08 /min
Retell AI offers fast, scalable voice agents with response times under a second and impressive developer flexibility. You can bring your own LLM, customize behavior deeply, and monitor everything through real-time dashboards. It’s well-suited for teams with in-house engineering that want control and scale. But the learning curve is real—getting up and running takes work, integrations often require custom scripts, and pricing isn’t transparent. While it performs well under the hood, Retell isn’t the most approachable platform for teams seeking simplicity or industry-ready templates out of the box.

Bland AI
Bland AI charges $0.09 per minute plus a monthly fee, offering basic phone automation with a minimalist interface. But it only supports English by default, only integrates with Twilio, and charges extra for features like voice cloning or concurrency. While it’s pitched as developer-friendly, much of the work—like setting up context management or error handling—falls on you. The voice often sounds flat or overly scripted, and the system can struggle to handle complex flows without dropping threads. It’s an entry-level solution that quickly shows its limitations.
