What is Ibis?
Ibis is a federated encyclopedia built on the ActivityPub protocol for decentralized wiki hosting. Users can create, browse, and edit articles with full edit history, discussion pages with nested comments, and conflict handling for concurrent edits. The software supports markdown with extensions such as LaTeX, table of contents, footnotes, and spoilers. It features a snappy editor with live preview, dark mode, an explore page for discovering articles, and a notification system. Ibis can be self-hosted via a standalone executable or container image with a PostgreSQL database. Federation keeps articles mirrored across instances so they stay readable even when the origin goes offline. The project is licensed under AGPL-3.0.
