An open-source hybrid integration platform for connecting applications, data, and systems with enterprise-grade features.
WSO2 Enterprise Integrator is an open-source hybrid integration platform that enables developers to connect applications, data, and systems across on-premise, legacy, and cloud environments. It provides a comprehensive set of integration capabilities including service mediation, message brokering, business process orchestration, and analytics. The platform helps organizations achieve digital agility by transforming messages between formats, protocols, and standards.
Enterprise integration developers, middleware architects, and DevOps teams building sophisticated integration solutions for digital transformation. It's particularly valuable for organizations needing to interconnect heterogeneous systems across government, healthcare, banking, education, and communication sectors.
Developers choose WSO2 Enterprise Integrator because it offers a mature, production-proven open-source alternative to commercial integration platforms with full enterprise capabilities. Its unique value lies in the comprehensive multi-profile architecture that combines traditional ESB functionality with modern cloud-native approaches through the Micro Integrator, all while being actively maintained with commercial support available.
An open source, a high-performance hybrid integration platform that allows developers quick integration with any application, data, or system.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports all enterprise integration patterns, 185+ connectors, and multiple protocols like HTTP and JMS, making it versatile for complex integrations across heterogeneous systems.
Actively maintained since 2005 with commercial support from WSO2 Inc., proven in production by Fortune 500 companies in sectors like healthcare and banking.
Includes ESB, Message Broker, Business Process, and Analytics profiles in one platform, providing a complete middleware solution for diverse integration needs without separate tools.
Offers WSO2 Micro Integrator as a cloud-native option for microservices environments, enabling modern composite microservices development alongside traditional integration flows.
Building from source involves a hierarchical structure of 15+ dependent repositories, as shown in the README, making initial setup and customization daunting for new users.
The full distribution includes all profiles, making it heavyweight and potentially overkill for basic API proxying or simple message routing, with higher memory and CPU requirements.
While open-source, it relies on WSO2-specific tools like the WSO2 Store for connectors and management consoles, which may limit interoperability and flexibility compared to framework-agnostic solutions.
