What Shower is

Shower is a free, open-source HTML presentation engine built with HTML, CSS, and vanilla JavaScript. Its core package handles slide management, navigation, a progress bar, and a timer. Themes remain separate from the engine, with Ribbon and Material included. Shower describes the presentations as fully keyboard accessible and supports the latest stable Chrome, Edge, Firefox, and Safari versions. Presentations can be printed to PDF. The command-line interface can create, serve, bundle, archive, convert, and publish presentations, including publication through GitHub Pages. Bundling creates a self-contained folder for static hosting, and the template can be edited by opening index.html in a text editor. CLI use requires Node.js; documentation lists Node v8.0.0 as the default minimum, while the CLI requirement is Node.js 22.0.0 or later. PDF conversion needs a browser implementing the Chrome Debugging Protocol. Shower uses the MIT license, but its GitHub repository is archived and read-only as of March 12, 2026.
