- Inbound Calls : Vapi powers over 400,000 calls daily. Quang Tran shared, “ A technical requirement was the ability to bring our own stack - Vapi developer friendly API - first approach made this possible.”
- Outbound Calls : Vapi manages overflow calls seamlessly. James Morrow noted, “We are now seeing better payouts on our Vapi agents calls for healthcare customers than we do it on the equivalent web from which was a big breakthrough moment for us.”
- Tool Integration : Easily connect your voice agents to APIs, databases, and existing systems for smooth, end-to-end integration.
Cons :
- Time-Intensive and Iterative Process: Achieving a reliabile and accurate voice bot on Vapi often requires enduring a prolonged development process and continuous refinement. The bot has to be manually tested again and again after each change by talking to it.
- Need for Deep Prompt Engineering Experience: Building on Vapi requires deep expertise in prompt engineering with voice bots. Users struggle to create natural interactions, leading to sub-par user experience.
- Technical Learning Curve : Vapi’s advanced features add complexity, often requiring coding, API knowledge, or design skills challenging for non-technical users or small teams.
- Layered Pricing : Though Vapi promotes low rates ($0.05/min), real costs often rise to $0.25–$0.33/min due to separate charges for LLMs, STT, TTS, and telephony making cost control a challenge.
- Limited Out-of-Box Templates & Channels : Vapi is heavily focused on phone automation, offering limited support for chat, SMS, email, or web embedding, and fewer prebuilt workflows than competitors.
- Security Gaps : Lacks ISO 27001 certification, role-based access control (RBAC), and default access logging.
- UI Limitations : The GUI does not support real-time prompt previews or fallback mapping functionality.
- Inconsistent Voice Quality : Voice output quality can vary based on the selected model configuration.
- Support & Documentation Issues : Some users report inconsistent support and difficulty with documentation, particularly during major updates or fast development cycles.
- Not ideal for Non-Technical Teams : Vapi offers a no-code builder, its full potential is unlocked by teams with strong technical resources making it less suited for users seeking all-in-one simplicity or prebuilt automations.

Vapi AI App Review
Vapi is a powerful tool for voice automation designed for developers and enterprises. It offers low latency sub 600ms, supports complex workflows and integration. Without engineering support from team will face delays in deployment and updating the agent.
Vapi lacks robust debugging and testing tools, making it harder to assess and optimize voice agent performance effectively. This can slow iteration for developers.
These guys are top-tier. They're improving rapidly as the tech grows and continue to impress with their customer service and responsiveness.
Terrible customer service bot!! no support for UK to buy numbers so if from UK you will pay twice to make one call, they use lots of misleading terminology like import the number when really your just setting it up to work in VAPI. terrible service - GIVE UK NUMBERS
