2. Stability and User Experience: While Bland AI may offer more features, it frequently experiences issues, with things breaking and an inconsistent UI that can confuse users. Retell, on the other hand, prioritizes stability and a seamless user experience above all else.

3. Flexibility and Multilingual Support: Retell has native multilingual capabilities, enabling users to switch between languages like Spanish and English within the same call. It supports 19 languages, including English, Spanish, French, German, Chinese, Hindi, Portuguese, Italian, Russian, Dutch, and more. In contrast, Bland AI only supports English. Retell also allows customers to use their own telephony providers—not limited to Twilio or Vonage—giving you the flexibility to choose any VOIP provider you prefer.

4. Reliability and Scalability: Bland AI boasts a 99.94% uptime, but Retell consistently maintains a higher uptime of 99.99%, making it more reliable. Retell also supports millions of phone calls and has numerous enterprise customers in production, ensuring it scales efficiently for any business need.
