What is Voximplant?

Voximplant is a serverless cloud communications platform that gives developers APIs and SDKs to add voice, video, messaging and SIP trunking to web and mobile applications, with SDKs for iOS, Android, React Native, Flutter, Unity and the web. Its VoxEngine scripting environment lets teams build call scenarios in JavaScript, and the platform integrates with AI providers including OpenAI, Google Gemini, Dialogflow and xAI's Grok for real-time speech-to-speech voice agents, plus speech recognition, text-to-speech and call transcription.

Pricing is pay-as-you-go rather than tiered subscriptions: outbound voice calls start from $0.017 per minute, inbound calls at $0.005 per minute, SMS at $0.016 per message, and phone numbers from $1.50 per month. Video conferencing includes a free tier of 15,000 minutes per month, and new developers can create a free account to explore the platform before charges apply. Voximplant Kit adds a no-code contact center and IVR builder on the same platform.
