Create,
Communicate, and
Collaborate

Composer is the truly open platform for content creation and collaboration.

Leveraging the open DXOS decentralized framework, Composer replaces the traditional monolithic application model with a flexible and modular approach, enabling users to seamlessly integrate and edit components from different software providers within a single document.

Composer promotes interoperability and component reusability, allowing for the embedding and manipulation of various types of media and data. With its innovative concept, Composer aims to set a new standard for document creation, offering a powerful alternative to existing closed-source SaaS applications.
