What Is Known

Known is an open-source social publishing engine built around the idea that individuals and groups should own their content rather than renting space on a closed social network. A single Known installation can serve as a personal blog or as a shared site for a whole community, with unlimited collaborators able to post to the same domain.

The project was co-founded by Ben Werdmuller and Erin Jo Richey and formally launched in 2014 after being incubated at the Matter Ventures media-startup program in San Francisco. Werdmuller's earlier work on the open-source platform Elgg fed directly into Known's design philosophy of decentralized, user-owned publishing.

Known follows the IndieWeb principle of publishing on your own site first and syndicating copies elsewhere (POSSE), rather than posting natively into a third-party platform's feed and losing control over that content.

Key Features

A single post in Known can be a blog article, a short status update, a photo, a bookmark, or another supported content type, all managed from one interface. A browser bookmarklet lets users quickly save or comment on pages they find elsewhere on the web.

Sites support custom domains, custom CSS and JavaScript, hashtag-based content organization, and both raw HTML and WYSIWYG editing. Output feeds are available in RSS, XML, JSON and KML so other tools and services can consume a site's content programmatically.

Because it is self-hosted, Known gives operators full control over privacy: a site can be fully public, a private single-author journal, or a closed group space for a defined set of collaborators.

Pricing

Known is distributed as free, open-source software that a user downloads and installs on their own PHP hosting, so there is no vendor subscription fee for the software itself -- the only ongoing cost is whatever web hosting the operator chooses.

There is no current tiered commercial hosted plan comparable to WordPress.com; anyone who wants a managed Known site is generally expected to install it on standard shared or cloud PHP hosting themselves or work with a developer to do so.
