Voiceflow vs Vapi

Voiceflow is a leading conversational AI platform designed to empower product teams in building, deploying, and scaling impactful AI agents across a wide range of use cases. Founded in 2019, Voiceflow emerged from a need to simplify the complex process of building AI agents, which had previously been limited by either overly simplistic tools or rigid legacy platforms.

Our mission is to provide a flexible, collaborative, and extensible platform that enables teams to build AI agents that are as powerful and intuitive as websites or mobile apps. Voiceflow’s mission is to empower ambitious teams to build the world’s best AI agents.

Vapi.ai offers a cutting‑edge voice-driven UI/UX and SDK for devs. Integration with platforms like iOS shortcuts or React via NPM has been attempted by some developers. Build, test, and deploy advanced voice AI agents in minutes with Vapi. The platform for developers creating conversational voice AI. 

It combines speech-to-text, large language models (LLMs), and text‑to‑speech, giving you full control over each component—such as choosing providers like OpenAI, Anthropic, Deepgram, ElevenLabs, and others. Vapi CEO Jordan Dearsley shares how Vapi grew to $8M over the past 5 years. Vapi has raised $20.1M and hit a $13.5M valuation in 2025.
