The new app will come with several features such as the ability to post threads, direct messaging, voice capabilities, code repositories, and automated workflows. The platform has been designed to be model agnostic, decentralised, self-sovereign, and open-source. Buzz’s open-source nature means that developers can customise their own instances based on their preferences and specific workflows. They can easily build a new feature and deploy it on their own since the developers will have full access to the underlying source code of the platform.
