As businesses increasingly pivot call operations to AI voice agents to streamline customer interactions, choosing the right AI call platform becomes critical. While both Retell AI and Vapi AI offer AI phone agent solutions, they cater to drastically different user bases and subsequently business needs. Let's explore the key differences between the platforms to help you decide the best option for your business.
One of the biggest distinctions between Retell AI and Vapi AI is accessibility. Vapi, being API first, centers their platform on being massively customizable through the necessity of developing most aspects of your AI phone agent and its processes through code. Most features and APIs must be coded by a developer to be integrated or be connected through third party integrations. There are hardly any templates or frameworks to make and deploy agents quickly.
On the other hand, Retell has built its platform with the same customizability in mind, yet with a higher emphasis on ease of use, scalability, and deployment. Within the agent builder there exists template, feature, and integration options that allow for users to easily access the tools they need to make their highly personalized phone agents. Retell AI offers pre-built functions in the form of integrations, helping you build your voice agents that much faster.

While code is a must for any complex and specialized voice agents, removing the majority of the code bottleneck allows agents to be built in as fast as 5 minutes!
The key when navigating the choice between a code heavy solution like Vapi and a code optional solution like Retell is having a deep understanding and reflection on your business’ needs. If your business requires a hyper customized AI voice agent solution then a platform code heavy platform will be the tool to use, but if time and resources are limited, which it is for most, an all-in-one solution with large support for customization may be the right choice for you.
Overall:
AI voice agents should sound as human as possible right out of the box. Callers and recipients to calls want to hear a human not a robot, and furthermore they need the agent they are speaking with to understand their needs and act on them, just like human agents do. A platform that offers these key capabilities in their agents is imperative to maintaining and retaining trust, customer satisfaction, and efficient workflows in your outbound and inbound call operations.
Vapi AI, while being highly customizable, offers limited support for agent optimization, lacking key features like context retention between transfers and voice option upgrades hidden behind paywalls. These features leave Vapi AI phone agents sounding less human and less capable to assist and execute on complex functions.
Additionally, Vapi’s complex and overwhelming user interface is a significant pain point for beginners and developers alike. Vapi users often report feeling frustration from attempting to build their business’ voice agents due to the amount of confusing settings and functions. You shouldn’t need to translate hieroglyphics to build an AI phone agent, with a simpler and easier solution built to shatter your potential bottlenecks: Retell AI.
Retell AI provides advanced conversational AI with live context retention, ensuring that voice agents remember previous interactions within a call, making conversations feel more human and natural. Enhanced with key features such as webhooks, warm transfers, and IVR navigation, Retell’s agents are highly capable and more than equipped to handle simple and complex conversations and tasks. Additionally, Retell AI supports pre-trained AI voices optimized for conversation depth and sounding natural, so no matter how simple or complex the demands of your voice agents are, Retell’s agents will handle them with the sound of natural human speech.
Overall:
Cutting edge technology shouldn’t come at cutting edge prices. Vapi being reliant on APIs, charges an additional cost per minute, per API. That means you’ll be paying an additional cost for the model, transcriber, voice, and telephony on top of the $.05/min it already costs to use the platform. This ultimately makes the price unpredictable from the beginning and due to needing a developer to make functional AI phone agents, Vapi may become very cost inefficient overtime.
Retell AI, priding itself on providing a cutting edge all in one solution, recognizes that not all users need all the features, so the pricing model is modular. There are extra features and functionalities such as Branded ID Calling that businesses can choose to add to their plan. With a transparent and straightforward pricing model starting at $.07/minute, your business can have everything it needs and nothing it doesn’t at an accessible rate.
