The blog post from Ambassador announces two new features in Blackbird that enhance integration with GitHub to help manage API development and combat API sprawl. The first feature, already available, is an API discovery tool that automatically detects and imports OpenAPI specifications from GitHub repositories, ensuring they remain up-to-date and consistent across the API ecosystem, which aids in onboarding and reduces sprawl. The second feature, to be released soon, will generate OpenAPI specs directly from code, facilitating documentation of legacy and existing APIs and simplifying onboarding and discovery processes. Both features are designed to streamline the API lifecycle by maintaining Git as the central source of truth and providing a centralized, collaborative platform for API management.
