Beaker Browser uses the Dat protocol to provide a fully decentralized platform for publishing and accessing websites. Under the hood, Beaker uses Chromium (the open source component of Google Chrome) so it works with the majority of websites that work in Chrome. However, in addition to supporting the usual http and https protocols for accessing websites, Beaker can also access websites that were published as Dat datasets. Websites published in this way do not live in any central server. Instead, visitors all have a copy that they share among each other, with each visitor providing additional redundancy and bandwidth for the site. Beaker also includes a website editor and a one-click publishing system for creating new Dat-based websites. The take a tour link at the bottom of the home page contains a detailed tutorial on creating, publishing, and updating a decentralized website. Beaker is available for Windows, macOS, and Linux. Beaker is free software, distributed under the MIT license, with source code available on Github.
