Mbin

Mbin is a decentralized content aggregator, voting, discussion and microblogging platform that participates in the Fediverse via ActivityPub. It is a community-driven fork of kbin providing a web UI for submitting links, posts, comments and votes, and interoperates with other ActivityPub services.

Key Features

• Full ActivityPub support for federation with Mastodon, Lemmy, Pleroma, PeerTube and similar services
• Posting, link aggregation, threaded discussion, and up/down voting model for community moderation
• Web UI built with PHP and Symfony using Twig templates and JavaScript enhancements
• Docker and Docker Compose deployment options and documentation for bare-metal installations
• Multi-language support and community-driven translations via integrated localization workflow
• Code security practices with composer dependency management and regular audits

Use Cases

• Running a federated community forum or link aggregator that interoperates across the Fediverse
• Hosting a microblogging site with voting and threaded discussions similar to Reddit/Lemmy
• Integrating community-moderated content streams and magazines for niche interest groups

Limitations and Considerations

• Requires familiarity with PHP/Symfony and typical web hosting stacks for installation and maintenance
• Federation behavior can vary depending on ActivityPub implementations of other servers; interoperability nuances may require tuning
• Smaller project and ecosystem compared to some larger Fediverse implementations; administrative resources and third-party tooling are more limited

Mbin is suited for operators who want a community-focused, federated aggregator and discussion platform with active development and a focus on interoperability and usability.
