What is Evolution Api?
Evolution API (by Evolution Foundation) is an open-source messaging platform and set of tools designed to integrate and automate customer engagement across WhatsApp and other messaging channels. It provides a REST API, high-performance server implementations, SDKs and cloud SaaS offerings to help teams send and receive messages, manage sessions, and build automation flows. Key features include a Node.js/TypeScript REST API, a high-performance Go implementation (Evolution Go), DevOps-friendly Docker images and orchestration, omnichannel support in the cloud product, and extensive developer documentation and examples. The project targets startups, SMBs, and developer teams who need a self-hosted or cloud-ready alternative for WhatsApp Business automation, as well as integrators and agencies building conversational automation and growth tooling.
Evolution Api pricing
Pricing model: Freemium
The website and documentation describe a dual model: an open-source self-hosted core available free to use, and a managed EvolutionAPI Cloud (omnichannel SaaS) with paid plans for hosted convenience and additional features. The free tier consists of the project code and Docker images that organizations can run themselves at no license cost. Paid plans for the cloud product include hosted infrastructure, omnichannel connectors, and operational convenience, with higher tiers expected to include increased usage limits, SLAs, and enterprise features; exact plan names and prices are provided through the cloud product pages rather than as fixed public table pricing on the documentation site.

Frequently asked questions about Evolution Api
What is Evolution API and who should use it?
Evolution API is an open-source messaging integration platform and REST API designed for automating and managing messaging channels (originally focused on WhatsApp); it suits developers, startups, SMBs, agencies, and teams that need flexible self-hosting or a managed omnichannel SaaS option to build growth and engagement workflows.
Is Evolution API free to use?
The core Evolution API is open-source and free to self-host under the repository licensing, allowing teams to run the software at no licensing cost; a managed EvolutionAPI Cloud offering is paid and provides hosted infrastructure, connectors and operational support.
What languages and implementations are available?
Official implementations include the main Node.js/TypeScript REST API and a high-performance Evolution Go implementation, plus client SDKs and Docker images to support deployment and integration.
Does Evolution API support channels other than WhatsApp?
While the project began focused on WhatsApp, the ecosystem and cloud product are described as omnichannel, with connectors and architecture intended to support other messaging platforms through integrations.
How do I deploy Evolution API to production?
The project provides Docker images and documentation for deployment; production deployment requires standard operational practices such as container orchestration, secure key/session management, monitoring, and scaling according to message volumes.
What does Evolution Go provide compared to the Node.js version?
Evolution Go is a high-performance reimplementation aimed at lower latency and resource efficiency for large-scale messaging workloads, providing an alternative for teams that prioritize performance and Go-based infrastructure.
Where can I find documentation and examples?
Extensive documentation, getting-started guides and code examples are published on the Evolution Foundation docs site and in the open-source repositories, covering API endpoints, deployment patterns, and example integrations.
Can I use Evolution API with existing WhatsApp Business numbers?
Yes; the platform is designed to integrate with WhatsApp-related session and phone management workflows, but users must follow WhatsApp's terms and manage sessions/phone limits and any provider requirements when connecting real numbers.
Does the project offer official support or SLAs?
Official enterprise SLAs and managed support are implied to be part of the paid cloud/managed offering; self-hosted users rely on community support and their own operational processes unless they contract managed services.
