Contentful has released improved tools to sync content across development environments, replacing its deprecated Space-sync tool. The new tools, `contentful-import` and `contentful-export`, are designed from the ground-up to meet customers' needs and offer more flexibility. They have been refined to be more reliable, performant, and robust, with features such as better error management, support for rate limits, and improved handling of unexpected server errors. The tools also include a feature to manage existing entries in the destination space, allowing for seamless syncing between spaces. The modules are open-sourced on Contentful's Github page, enabling users to contribute and provide feedback.
