About

ActivityPub is a decentralized and open-source social networking protocol, officially recommended by the W3C Social Web Working Group, which also oversees its development. Founded as a W3C standard, it is based on the ActivityStreams 2.0 data format and serves as a foundational element for the Fediverse, enabling true social communication and federation. It offers features such as suggesting and voting on features, and is available for deployment on Self-Hosted and Wordpress platforms. Positioned as a critical open alternative, ActivityPub actively counters the trend of proprietary, non-interoperable 'walled bubbles' in social networking. While specific revenue and employee counts are not applicable to a protocol, its open-source nature and W3C backing highlight its unique market position. Development is transparently managed via GitHub, and updates are shared on Twitter. A user review praises its decentralized and open nature as a vital choice against proprietary systems.
