WSO2 Choreo

Digital transformation is reshaping business operations and society, delivering benefits such as reduced costs, greater agility, and improved customer insight, while also introducing new pressures: rapidly changing technology landscapes, a shortage of skilled IT professionals, and expanding security and compliance risks. As organizations increasingly behave like software companies, they must build and ship digital products faster than competitors and maintain extensive data-exchange channels with partners, contractors, and sometimes governments. This commonly converges on designing and productizing APIs, which have become the dominant integration method across platforms, applications, cloud services, and devices. Yet modern API development is no longer “easy REST”; it demands full-lifecycle management, multiple tools, and specialized skills, driving interest in managed services and citizen development via low-code/no-code approaches.

WSO2 positions itself as a long-standing open-source enterprise vendor (founded in 2005) that is expanding from complex hybrid enterprise projects toward pre-built cloud-native tools. Two key building blocks of this strategy are Asgardeo (Identity-as-a-Service) and Choreo, a cloud-native PaaS for rapid delivery of digital services. WSO2 Choreo is presented as a fully managed platform that spans API design, development, publishing, monitoring, and productization, emphasizing APIs and API proxies for integrations, microservices, and workflows.

Choreo’s core differentiator is its use of Ballerina, a WSO2-created language centered on sequence diagrams, enabling reversible visual-to-code development in a browser-based VS Code environment. The platform offers 500+ connectors, an integrated CI/CD pipeline with Kubernetes deployments, a marketplace for reusable components, and strong observability with analytics, alerting, and even early-stage performance prediction. Key limitations include youth (GA March 30, 2022), constrained customization, GitHub-only Git integration, US-only hosting with data residency planned via private data planes, and monetization not yet available.

• WSO2 was founded in 2005.
• WSO2 is headquartered in California, USA.
• WSO2 was founded in Sri Lanka and later grew into an international company with offices across multiple regions.
• WSO2’s open-source products include WSO2 Identity Server and WSO2 API Manager.
• WSO2 provides purpose-built accelerators for banking and healthcare industries.
• WSO2 Choreo’s first generally available release date was March 30, 2022.
• Choreo includes a browser-based developer environment built around Visual Studio Code.
• Ballerina has built-in support for XML and JSON.

• Choreo is currently hosted in the US, with non-US data residency planned via “private data planes.”

• “APIs are ubiquitous, serving as the main integration medium between heterogeneous technology platforms, distributed applications, cloud services, mobile and smart devices.”
• “Nowadays, everything is API-enabled.”
• “In a world where information is the ‘crown jewel’ of many businesses, APIs are now powering the logistics of delivering digital products to partners and customers.”
• “Modern API development, management, and security is a complicated endeavor that must cover the whole lifecycle of an API product and incorporate multiple tools, services and required skills.”
• “A comprehensive digital innovation platform - well-integrated yet extensible, enterprise-ready yet accessible to citizen developers, cloud-native yet supporting hybrid use cases – is what modern businesses need to keep up with the pace of digital transformation.”
• “Choreo focuses on developing APIs and API proxies as the single most popular method of creating integrations, microservices, and workflows in the modern digital, cloud-native world.”
• “Ballerina is entirely based on sequence diagrams: every piece of source code can be represented graphically as a flow diagram that outlines the program’s logic.”
• “This process is not only fully automated, but also completely reversible, meaning that any program can be created as a sequence diagram first, without the need to learn a new programming language.”
• “A major component of the platform is the Marketplace - the interface where developers can publish their new APIs for later reuse or even turn them into digital products.”
• “Choreo can already be recommended for almost any customer, regardless of their size or industry, at least for evaluation.”
