WSO2 API Platform Reviews & Product Details

WSO2 API Platform is an open source, unified control plane for managing APIs, AI, and event-driven traffic across cloud, hybrid, and on-prem environments. It enables organizations to design, secure, govern, and productize APIs while scaling agentic and LLM-based workloads with built-in governance and security controls. Teams use WSO2 to prepare APIs for AI agents with auto-generated MCP servers, centrally manage outbound LLM traffic, and gain full visibility into API and AI usage, performance, and cost. The platform supports bi-directional AI governance, covering both inbound agent-to-tool traffic via MCP and outbound app-to-LLM traffic from one control plane. Unlike traditional API management tools, WSO2 API Platform supports both human and agentic consumers from a single platform. It manages APIs across WSO2 and third-party gateways, including Kong, AWS, Azure, Envoy, and Apigee, with federated policy enforcement from a single control plane. Built-in monetization (powered by Moesif) lets teams meter, bill, and productize API calls and LLM token usage through connectors for Stripe, Zuora, Chargebee, and more. Key capabilities include: ➡️ Full lifecycle API management with MCP Gateway (auto-generates MCP servers from ➡️ OpenAPI specs) and LLM Gateway (routing, semantic caching, guardrails, PII masking, and token cost control). ➡️ Deep analytics for API and AI usage powered by Moesif. ➡️ Compliance support for HIPAA, PCI-DSS, FedRAMP, GDPR, DORA, SOX, ITAR, and EU AI Act, with integration for Azure Content Safety and AWS Bedrock Guardrails. ➡️ Flexible deployment: SaaS, Kubernetes, hybrid, and self-hosted. ➡️ 100% open source with zero vendor lock-in. WSO2 API Platform helps enterprises modernize their API programs, adopt AI responsibly, and turn APIs and AI services into secure, scalable digital products.

"The Best API Management Product"

5/5

What do you like best about WSO2 API Platform?

WSO2 API Manager provides a rich set of features to manage the entire API lifecycle, and compared to other vendors, it stands out with flexible deployment options across on-premise, hybrid, and cloud environments. As a user, I now also really like the AI-driven enhancements – especially the AI Gateway that lets me govern and manage AI APIs with guardrails, dynamic routing across multiple AI models, real-time analytics, and fine-grained controls for AI usage. I can expose my APIs as MCP servers for AI agents to discover and interact with, and I get smarter automation across design, testing, documentation, discovery, and governance with AI-assisted spec generation, natural-language testing, and AI-powered developer portal support. All of this makes API design, deployment, and lifecycle automation much more efficient and future-ready for AI-centric architectures. Review collected by and hosted on G2.com.

What do you dislike about WSO2 API Platform?

One area where WSO2 API Manager can improve is the upgrade process, which could be smoother and more streamlined. While upgrades are well documented, they can still feel complex and time-consuming in real environments, especially when dealing with multiple components and configurations. A more automated and simplified upgrade experience would make it easier to adopt new versions and features with minimal disruption. Review collected by and hosted on G2.com.

Recommendations to others considering WSO2 API Platform:

If you are looking for a flexible vendor-neutral API Management Product, then go for WSO2 API Manager. You will have the platform advantage coming from WSO2 which includes complete integration and identity management suit. Review collected by and hosted on G2.com.

What problems is WSO2 API Platform solving and how is that benefiting you?

API Manager is used as a central gateway to manage the APIs traffic in the organization. With the growing number of APIs and adoption of microservices architecture, it's required to have a central place to discover and manage the APIs. WSO2 API Manager provides a rich developer portal to discover the APIs. OpenAPI specification support in API Manager makes it easy to create and manage API definitions. With OAuth support, WSO2 API Manager acts as the centralized authentication and authorization layer for the internal APIs. Review collected by and hosted on G2.com.

What do you like best about WSO2 API Platform?

WSO2 API Manager has been significantly enhanced the product capabilities with industry standards. The latest release of WSO2 API Manager v4.5 has come up with API powered capabilities like- Create an API with design assistant, API chat to test the API, AI powered multi-model routing for different AI APIs definitely helps in optimal resource utilization. BYOG i.e. bring your own gateway support with WSO2 API manager is like a magic bullet to integrate existing gateways like AWS API Gateway or any custom one. We have tested out the feature and it work seamlessly.

I have also found the improvements in existing capabilities like role-based access control, improved logging and observability, auditing and API documentation. So now your API creator and publisher can see the key parameters missing while creating and publishing an API and that's a big move towards standardization of APIs.

GraphQL APIs creation has been simplified with the latest release.

The latest tutorials on their LMS portal (lms.wso2.com) is updated, so developers can quickly engage with the training and start using the features. Review collected by and hosted on G2.com.

What do you dislike about WSO2 API Platform?

Migration process can be improved. For API mocking capabilities are still lagging which is available in other platforms. Version 4.x is completely revamped, and I observed the backward compatibility is challenging. Devportal customization can be simplified. Review collected by and hosted on G2.com.

Recommendations to others considering WSO2 API Platform:

If you are planning for any API Management & Integration solution, WSO2 is the right choice which you can try at Zero cost.

"Review after 9 years usage."

4.5/5

What do you like best about WSO2 API Platform?

I have been using WSO2's API Manager product for over 9 years now, and I have followed its evolution since version 2.0.0. I have used version 2.0.0, then 3.2.0, 4.1.0, and currently version 4.5.0.

The product is a real asset and accelerator for managing our API catalog. We rely on its capabilities to provide both external public and internal private service catalogs. Beyond its numerous technical capabilities, the product supports us in managing and governing our API assets in the broadest sense.

Installation and getting started in standard mode is very easy and facilitated by extensive documentation available on the product website.

The implementation could be more tricky if you have special uses cases.

I recommend this product with a rating of 9/10, given that it is an open-source product, there is always room for improvement and evolution. WSO2 is a powerful and renowned publisher, and their teams are always available and do not hesitate to propose product updates if a client need makes sense to them.

I also recommend this product for its reliability in critical production environments, with an availability rate of approximately 99.97% to date. Review collected by and hosted on G2.com.

What do you dislike about WSO2 API Platform?

I don't necessarily have any drawbacks to address regarding the product. The only drawback I can find is the weakness of the documentation around version migrations. Review collected by and hosted on G2.com.

"A Powerful Enterprise API Platform Delivering Best Practice Solutions for Our Customers"

4.5/5

What do you like best about WSO2 API Platform?

The latest advancements with AI-powered agents for API creation help reduce workload and minimize human errors, making the development process smoother and more efficient. This adds another layer of value on top of the core strengths we already rely on, and it complements the platform’s ease of use. From real-world customer use cases, I’ve observed WSO2 API Manager handling high traffic loads seamlessly and reliably, which demonstrates its enterprise-grade scalability and stability. Review collected by and hosted on G2.com.

What do you dislike about WSO2 API Platform?

While WSO2 API Manager is a strong platform, there are areas where improvements could make the developer experience smoother. For example, policy management can be time-consuming since adjustments often require multiple edits or manual steps, and having a more streamlined policy editing console would be very beneficial. Additionally, when working with SOAP services, the platform does not expose the WSDL endpoint externally and instead attempts to handle all services as REST APIs. This makes it challenging to directly access or integrate with the underlying SOAP definition. Addressing these types of usability gaps with incremental enhancements and clearer tooling would greatly improve overall efficiency. Review collected by and hosted on G2.com.
