Feature Deep Dive

Language Support

Analysis: Edesy's 87+ language support is native and optimized. With Vapi, language support depends on which ASR/TTS providers you integrate, requiring more configuration.

LLM/AI Integration

Analysis: Edesy includes optimized LLMs for voice conversations. Vapi requires you to bring your own (OpenAI, Anthropic, etc.), giving more flexibility but requiring more setup.

Telephony

Conversation Management

Analysis: Edesy provides pre-built conversation flows for common use cases (support, scheduling, etc.). Vapi requires building everything from scratch, offering flexibility but requiring more development time.

Developer Experience

Edesy Development

// Edesy - Quick setup
const edesy = require('@edesy/voice-ai');

edesy.configure({
  phoneNumber: '+15551234567',
  greeting: 'Hi! How can I help you today?'
});

// Use pre-built intent handlers
edesy.onIntent('order_status', async (context) => {
  const order = await getOrder(context.customer.id);
  return `Your order ${order.id} is ${order.status}.`;
});

// Built-in Salesforce sync
edesy.integrations.salesforce.sync();

Edesy approach: Configure and extend. Pre-built components handle common cases.

Vapi Development

// Vapi - Build from scratch
const vapi = require('@vapi/sdk');

const assistant = vapi.createAssistant({
  model: {
    provider: 'openai',
    model: 'gpt-4',
    systemPrompt: `You are a customer service agent...`
  },
  voice: {
    provider: 'elevenlabs',
    voiceId: 'your-voice-id'
  },
  transcriber: {
    provider: 'deepgram',
    model: 'nova-2'
  }
});

// Handle all logic in prompts or functions
assistant.addFunction('getOrderStatus', async ({ orderId }) => {
  // Your implementation
});

Vapi approach: Full control. You configure each component and write all logic.
