Manage all components of Litmus in one place

Backstage is an open platform for building developer portals and is one of the most popular CNCF projects. It allows developers to manage cloud-native applications' numerous services and codes from a single point. Chaos engineering can verify an application's resilience. It gives you the opportunity to identify various vulnerabilities in your application. Therefore, having information about Litmus chaos experiments alongside other application elements, such as application code, and CI/CD pipeline information, is highly beneficial to developers.
