Spark

Spark is an open-source social media platform built on the AT Protocol. It addresses the loss of user trust in conventional social networks by placing control of timelines and data directly with users rather than a single company.

The platform allows anyone to create, host, code, and control their own custom feeds. Users can browse feeds made by others and add them to their home screen, freeing creators from catering to one algorithm and users from relying on a one-size-fits-all solution. Spark provides full transparency through its source code, which is publicly available on GitHub under the MIT license. The project accepts community contributions such as issue reports, feature requests, and pull requests, and its permissive license permits anyone to fork and modify the code.

Built on the AT Protocol, Spark supports portable accounts that let users switch providers without losing follows, posts, or identity. A single account works across compatible AT Protocol applications, and anyone can build independently on the platform. Its feature set includes search for profiles and videos, the ability to see which friends liked or reposted content, built-in direct messaging that supports sending posts privately, optional algorithms for personalized recommendations alongside chronological feeds, a photo and video editor for adding text, stickers, filters and more, and Stories that disappear after 24 hours.

Spark is free to use and fully open source. It is delivered as a downloadable application, with additional resources provided through its blog, support pages, and GitHub repository.
