EasyCoexistence vs Vonage

How the bill is built

Usage pricing and a flat fee behave differently as volume grows.

Vonage: Meta's fee per delivered message, plus a Vonage platform fee that starts at 0.0001 euros per message and adjusts by volume and region. Calls carry a further Vonage fee of $0.004 per minute.

EasyCoexistence: US$ 9 per connected number per month, falling to US$ 1 as you add numbers. Meta bills messages to your own WhatsApp Business Account and nothing is added per message by us.

Which numbers each one is built for

The number a small business already answers on is usually a WhatsApp Business app number.

Vonage: Its WhatsApp pricing page and its hosted Embedded Signup guide for partners do not address Coexistence, the Meta feature that keeps the app running on an API number.

EasyCoexistence: Coexistence numbers specifically. The WhatsApp Business app keeps its chats and keeps working on the phone, while the Cloud API runs on the same number at Meta's 20 messages per second Coexistence throughput.

What sits between you and Meta

Both are API products. What differs is whose API you call.

Vonage: The Vonage Messages API, a single interface over WhatsApp and their other channels. Your code calls Vonage, and Vonage calls Meta.

EasyCoexistence: Meta's documented Cloud API with credentials issued to your own account, and webhooks routed by Meta to your endpoint. Conversations are never stored on our side.

Which one to choose

A developer who wants one API across SMS, RCS, email and WhatsApp is buying multi-channel CPaaS, which is a different product from a WhatsApp connection.

A business or agency that needs WhatsApp Business app numbers on Meta's own API, without a fee on every message and without a new number, needs Coexistence. EasyCoexistence provides it self-serve in about two minutes, monitors each connection continuously, and exposes the number to Claude, ChatGPT or Cursor through an MCP server.
