After 9 years of using integration technologies, such as ESB 5.0.0, EI 7.1.0, MI 4.1.0, MI 4.5.0 (as well as using Ballerina, which is not the subject of this review), I can therefore provide a fairly informed opinion.

WSO2 integration products are robust, powerful products that allow you to integrate virtually anything you want. By learning the syntax and with good logic, you can integrate everything.

Performing protocol transformations REST > SOAP > REST is child's play, and data mapping with internal components is also facilitated.

There have been many improvements in the product, particularly in the IDE part which was lacking until now. Integrator Studio was slow and didn't load Maven dependencies and modules, but this has been resolved since the arrival of plugins for Visual Studio Code.

We have operated on several approaches: the service bus approach with a good number of deployed integrations, ETL as well. Now we are using the micro integration approach, which facilitates the build and run of our applications.

I highly recommend this product, provided you are familiar with XML! Review collected by and hosted on G2.com.

I have few criticisms, except for weak documentation on complex cases.

Also regarding version upgrades where documentation may be lacking.

Debugging is also complex to implement.

There is also no documentation on the DevOps part for deployments from CI/CD.

(Given that WSO2 integration projects behave like Java Maven projects, CI/CD is rather simple) Review collected by and hosted on G2.com.

WSO2 Micro Integrator stands out for its lightweight footprint and cloud-native architecture, making it perfect for microservices and containerized environments. The built-in support for a wide range of integration protocols (HTTP, SOAP, JMS, etc.) and connectors (including Salesforce, SAP, etc.) makes it highly versatile. I especially appreciate its native support for CI/CD, containerization (Docker/Kubernetes), and observability (Prometheus, OpenTracing). The tooling with WSO2 Integration Studio makes it easy to design, deploy, and debug integrations visually, which accelerates developer productivity. Review collected by and hosted on G2.com.

The initial learning curve can be steep, especially for developers not familiar with the Synapse configuration language or the WSO2-specific deployment model. Although the documentation is comprehensive, some use cases lack detailed examples or community Q&A. Also, debugging complex mediation sequences can be challenging without deep knowledge of the runtime and logs. Finally, while the product is open-source, enterprise support and additional features are locked behind a subscription, which could be a limitation for small teams.

WSO2 Enterprise Integrator stands out for its comprehensive support for various integration patterns, including REST, SOAP, JMS, and Kafka, making it highly versatile. As an open-source platform, it offers strong flexibility and customization options, supported by a wide range of connectors. Its lightweight architecture, cloud-native readiness, and seamless integration with WSO2 API Manager further enhance its appeal for modern enterprise needs. The graphical Integration Studio also simplifies development and accelerates deployment. Review collected by and hosted on G2.com.

WSO2 Enterprise Integrator has a steep learning curve, particularly due to its XML-based configurations. While it offers extensive features, some users find the documentation lacking clarity for practical implementation. Additionally, community support is limited compared to commercial support, which may be necessary for critical enterprise deployments. Review collected by and hosted on G2.com.

From the demos at WSO2Con, it’s clear that WSO2 Integrator offers a powerful and flexible platform for enterprise integration. The low-code tooling for building integration flows, along with built-in support for APIs, events, and messaging, stood out. As someone from the hospitality sector, I see strong potential for using WSO2 Integrator to bridge systems like PMS, POS, ERP, and payment gateways. The ability to expose internal services as APIs, handle transformations, and orchestrate workflows in real time is critical for modern hospitality operations, especially with multi-property setups and third-party vendors.

Since my exposure was limited to the demos, it’s hard to evaluate real-world complexity. Review collected by and hosted on G2.com.
