Omnom

Omnom is a self-hosted content preservation and web bookmarking platform that lets individuals and communities save and archive web content in a way that reflects exactly what they saw in their browser at the moment of capture. Unlike simple bookmark lists, Omnom makes full page snapshots — including dynamic content — so that saved pages remain viewable even if the original goes offline or changes later. It was built with a multi-user web interface and includes support for federated social protocols like ActivityPub, allowing integration with decentralized networks and community tools. The application lets users categorize, tag, and search saved content, aggregate RSS/Atom feeds, and review changes between captured snapshots with diff views. A browser extension for Chrome and Firefox makes it easy to add new bookmarks and initiate snapshots directly from your browsing session.
