1. Pricing: Vapi has a higher pricing structure, with separate platform and component fees. For example, using GPT 4omini on Vapi costs $0.056/min for the component fee, plus a platform fee of $0.05/min, and a telephony fee of around $0.01/min, totaling $0.116/min. In contrast, Retell simplifies pricing by adding only a small margin on top of the component fees. For 4omini + 11labs + telephony, the total is just $0.09/min—25% cheaper than Vapi. Additionally, while Vapi charges $5,000/month for a Slack group, we offer this service free for all our enterprise customers.
2. Reliability and Scalability: Vapi has an uptime of 99.94%, while Retell consistently delivers a higher uptime of 99.99%, making us the more reliable choice. Retell supports millions of calls and has numerous enterprise clients in production, ensuring we scale smoothly with your business as it grows.
3. User Experience: Retell offers a more intuitive agent builder experience. In comparison, Vapi’s agent builder is not as user-friendly and has a steeper learning curve, making Retell a better choice for ease of use.
