What Evolution API is

Evolution API is an open source REST API for WhatsApp and other messaging channels. Each connected number becomes an instance, and your system sends messages, receives replies and queries contacts with simple HTTP requests, with no paid middleman.

There are two connection modes. Baileys is free, uses the WhatsApp Web protocol and connects by scanning a QR Code, as on your phone. Meta's official Cloud API requires a business manager account and may charge per message.

The app includes a management panel with a list of instances and the status of each number. It is also where you find the integrations with n8n, Chatwoot, Typebot, OpenAI, Dify, Flowise, Bot Evolution and EvoAI, plus Webhook and WebSocket events.

What Evolution API is used for in practice

Customer support with Chatwoot

Connect the company number to Chatwoot and answer on WhatsApp with multiple agents, conversation history and labels.

Automations with n8n

A new order, an invoice close to its due date or a lead from your website can become an automatic message. With n8n on the same VPS, the whole flow runs on your own server.

Chatbots and AI

Typebot, OpenAI, Dify or Flowise answer customers and hand the conversation to a person when needed.

Notifications from your system

An ERP, online store or course platform sends confirmations and reminders by calling the API with the number and the text.

Several numbers on one server

Sales, support and billing stay in separate instances, each with its own key and QR Code.

Monitoring alerts

Uptime Kuma can send notifications through Evolution API, so a website going down becomes a message on your WhatsApp.

Webhooks and WebSocket

Every incoming message generates an event sent to your system instantly.

Integrations in the panel

Plan	Best for
Basic 2 vCore · 2 GB	Recommended: runs Evolution API with PostgreSQL well, for those who connect a few WhatsApp numbers and have a moderate message volume.
Plus 2 vCore · 4 GB	For those who connect more numbers or have message peaks and want extra memory and disk space.
Pro 4 vCore · 6 GB	Suited to operations with many connected numbers, high message volume and other services running on the same VPS.
Turbo 4 vCore · 12 GB	For heavy use, with many simultaneous numbers, a large message history and a need for plenty of memory and storage.

Frequently asked questions

Evolution API hosting: frequently asked questions

How much does Evolution API hosting cost?

Evolution API is free, so you only pay for the VPS, from per month on the Start plan. With the Baileys connection there is no per-message charge.

Is Evolution API the official WhatsApp API?

No, it is an independent project. It connects through Baileys, which uses the WhatsApp Web protocol, or through Meta's official Cloud API. The type is set when you create each instance.

Can my WhatsApp number get banned?

Yes, if WhatsApp treats the usage as spam. Only message people who expect to hear from you, and for high-volume sending, prefer the official Cloud API.

How many WhatsApp numbers can I connect?

Evolution API sets no limit. The limit is the memory of the VPS, since each connected instance uses some. The larger the plan, the more numbers fit.

How much RAM does a VPS with Evolution API need?

The app requires at least 1024 MB of free memory. In our measurements, it uses about 380 MB when idle, including the database. For real use, Basic is the recommended plan.

Can I use it with n8n and Chatwoot?

Yes, both integrations are in the Evolution panel. n8n and Chatwoot can be installed on the same VPS, each with its own address, as long as there is free memory.

Who updates a self-hosted Evolution API?

The delivered version is 2.3.7 and stays fixed, so an update does not break your connections without warning. You update whenever you want, over SSH with root access, preferably after testing.

How do I start over or get help?

From the VPS panel in the client area you can reinstall the server, which erases the data and requires connecting your numbers again. 24/7 support in Portuguese covers the server side, and using the app follows the project's documentation.
