A component management platform includes a component library that stores software components to be incorporated into applications, such as components that have been optimized for efficient performance, reliability, and/or other aspects. The platform also provides a workspace that is accessed to create an application that includes component(s) stored in the component library. In some instances, a developer modifies component when incorporating the component into their application. The platform enables the developer to upload the modified version of the component, which is stored in the component library and published, through the platform, to enable others to incorporate the modified version of the component into their application projects. In some implementations, the modified version is tested for backward compatibility with previous versions of the component, and to verify that the modified version does not include any bugs.
