Valuable Features

WSO2 API Manager offers valuable features like flexible architecture, open-source nature, easy adoption, API lifecycle management, user-friendly interface, and scalability. Users highlight its containerized solution, micro-gateway, seamless orchestration, comprehensive security features, integration capabilities, and extensive documentation. It accommodates custom solutions, supports multiple databases, provides real-time monitoring, and enables efficient API publication and management. Its robust analytics and strong internal API security further enhance its usability and efficiency.
  • "The capability to define processes and seamless integration with APIs enhances our operations."
  • "The most beneficial feature of WSO2 API Manager is its capability to use Swagger to define and then populate the API."
  • "WSO2 API Manager provides strong internal API security, including token-based authentication and HTTPS support for various formats like REST. However, the newer API security features that are emerging are not available yet. They might be in development, but for now, internal API security is well-covered."

Room for Improvement

WSO2 API Manager has a complex interface that users find outdated and difficult to navigate. Users desire a more modern, user-friendly interface with streamlined role-specific access. Customization and documentation require improvement to aid non-technical users. The pricing and licensing are considered expensive. Users report integration issues, limited flexibility, and challenges with support and security compliance. Improving speed, latency, and monitoring capabilities would enhance the overall experience.
  • "We have encountered some concerns with concurrency. Our integrations do not handle high-volume transactions, and when benchmarking, some issues arose with concurrent testing."
  • "Dashboards for application monitoring of the APIs would be beneficial, allowing us to check for faulty APIs."
  • "WSO2 API Manager could improve by adding external API security features, which is one area where there is room for enhancement. Internally, API security is strong, and all other necessary features are already available. It has a solid marketplace, supports both Docker and standalone setups, and offers great enterprise integration. The developer portal has greatly improved the user experience, making it simple and user-friendly wherever we’ve implemented it. Overall, it’s not as complicated as other API gateways."

ROI

WSO2 API Manager offers a comprehensive feature set in its open source version, providing flexibility and extensibility. Users saw high ROI due to lower licensing fees compared to competitors and robust functionality. The manager enhances operational efficiency by reducing code duplication and cutting costs. Valuable support, including real-time assistance, contributed positively to user experiences. However, some users reported they did not feel a significant return on investment. Overall, WSO2 API Manager is effective in saving time and improving value.

Pricing

WSO2 API Manager offers both a free open-source version and a subscription-based model for enterprise support. Many find the open-source version cost-effective and appreciate the comprehensive features available in the paid subscription. While some regard the solution as affordable, others find the enterprise pricing high compared to competitors. Costs can vary significantly, often influenced by the desired features and deployment needs. The subscription includes several benefits, such as development machines and pre-production environments, without extra licensing fees.
  • "The challenge is the increasing pricing, which has led some customers to consider alternatives, like using Spring Boot solutions instead. The rising costs, especially as cores and usage increase, have been a concern, prompting some to migrate to other products."
  • "As far as I'm aware, the costs are not minimal but satisfactory."
  • "WSO2 API Manager is an open-source solution."

Popular Use Cases

Organizations use WSO2 API Manager for API management, digital integration, and security management. They leverage it to publish APIs, support microservices, convert SOAP to REST services, and serve as an integration hub. It's used for external API exposure, enabling digital service innovation, and supporting multi-region deployments. Companies also value its identity and access capabilities, API monetization potential, and orchestration functions across cloud environments, exemplifying flexible API lifecycle management and business process integration.

Service and Support

Customer service and support of WSO2 API Manager have mixed perceptions. Many find the support helpful, with quick and effective assistance available for those with enterprise-level subscriptions. Open-source users rely on community resources and documentation, which are often praised as helpful. Others mention challenges such as slow response times and unclear support models. Satisfaction levels vary, with some having positive experiences, especially when directly engaging with the product team.

Deployment

For many, WSO2 API Manager's initial setup is straightforward and simple for technical users, allowing installation within hours. However, some find complexity in coordinating components or during Kubernetes migration, which may extend setup time to weeks. Templates and defaults assist with ease, while those less familiar with the system may face challenges. Experience levels impact setup duration, which can range from a few minutes to several weeks depending on deployment type and intricacy.

Scalability

WSO2 API Manager is generally regarded as scalable, with some users noting ease of scaling through containers or Kubernetes. It handles different configurations and can manage high traffic without issues. However, some components may be challenging to scale, requiring manual provisioning. The flexibility to scale horizontally and vertically is appreciated, and its integration with existing and third-party infrastructures enhances usage. Users rate scalability positively but suggest improvements in certain areas like latency.

Stability

Feedback indicates WSO2 API Manager is mostly stable, but some users report memory issues affecting performance. Users rate its stability from five to nine out of ten, often depending on deployment practices. Complexity can introduce glitches but is generally manageable, especially with updates. Organizations find Tomcat integration reliable, though open-source versions may present version-specific bugs. Robust for low-concurrency use, though resource consumption might impact stability under certain conditions. Stability is often rated as good.

WSO2 API Manager Reviews Summary
Author infoRatingReview Summary
IT Engineer at Reliance Industries Ltd4.0I had a positive experience with WSO2 API Manager due to its ease of API deployment, CORS management, and robust analytics. However, it lacks flexibility compared to Apigee, which offers greater customization options. Human support provided excellent value.
Senior Principal Architect at 6d Technologies4.0We use WSO2 API Manager to integrate telecom products with third-party REST APIs by orchestrating service processes. Its API key-based security and process definition capabilities are valuable, though concurrency issues need addressing to handle high-volume transactions efficiently.
Head Of ITG Shared Applications Division at PSBank4.5We use WSO2 API Manager for our microservices and APIs both internally and externally. Its ability to use Swagger, robust security features, and cost-saving advantages by creating one API for multiple channels are invaluable, though monitoring capabilities could be improved.
Senior Solution Architect at Hewlett Packard Enterprise5.0I first used WSO2 API Manager with Wipro for banks, Telcos, and government clients in India to create an API marketplace. It excels in internal API security and ease of use, though lacking in external API security features.
Director at Java Riyadh4.0In the telecom sector, I find WSO2 API Manager valuable for its free access and features like the Publisher API and WSO2 Enterprise Service Bus. Continued open-source availability is crucial, especially in regions like the Gulf and Saudi Arabia.
Co-Founder and Chief Technology Officer at Asante Digital Group4.0I use WSO2 API Manager to expose and manage APIs securely, with features like version control and documentation. The tool offers high ROI due to cost-effective licensing, though pricing flexibility could improve. It's robust despite occasional forced integrations.
Senior Manager at Wavenet International Pvt Ltd4.0We use WSO2 API Manager for reselling and integration, finding features like blacklisting and whitelisting helpful. We integrate additional features ourselves and create custom dashboards. Pricing varies, posing challenges, but the solution saves us time.
Senior Principal Architect at 6d Technologies4.5We utilize WSO2 API Manager as an API gateway between the API and orchestration layers, appreciating its flexible mapping and real-time monitoring. However, we experienced latency issues with large scaling. It superseded our previous lightweight solutions, meeting our complex needs.
