What each one is
impress.js
impress.js is a JavaScript framework for building presentations that run in a web browser. It uses CSS3 3D transforms and transitions to move between slides placed in a large canvas, inspired by the zoomable style of prezi.com. You write the presentation as HTML and CSS, and the library handles the movement between slides.
remark
remark is a JavaScript library that renders a slideshow in a web browser from Markdown text placed inside an HTML file. You write slides separated by dividers, open the page, and it displays them. It is aimed at people who already know some HTML and CSS, since styling is done with ordinary CSS.
Best for
impress.js
- Web developers who want a custom, browser-based slide deck
- Designers who want spatial, animated slide layouts
- People presenting from their own laptop in a modern Firefox or Chrome browser

remark
- People comfortable with HTML and CSS who want slides written in Markdown
- Developers or teachers who want a presentation they can version-control as plain text
- Presenters who want a speaker-notes view with a cloned display
Strengths
impress.js
- Based on standard CSS3 transforms and transitions, with no jQuery or other JavaScript libraries required
- Core is a single JavaScript file that does not depend on Node or npm at runtime, according to the README
- Has a documented API reference, a Getting Started guide, and an official demo with commented source
remark
- Simple model: one HTML file with Markdown slides inside
- Presenter mode with speaker notes and a cloned view
- Works on touch devices with swipe navigation
Not ideal for
impress.js
- People who need a point-and-click editor, since the README describes the separate Impressionist project for visual editing and does not describe a built-in editor
- Anyone who needs reliable display for many visitors on older browsers, since the README says some visitors may not see presentations correctly
- People who want a no-code tool, since the work is done in HTML, CSS and JavaScript
remark
- Non-technical users who want a visual slide editor, since the README describes editing HTML and Markdown by hand
- People who need an offline presentation without building remark first, since the README notes the local boilerplate requires a build step
- Users who need built-in PDF export, since the README says PDF output relies mainly on Chrome's Print to PDF and styling is not exact
Trade-offs
impress.js
- Browser support is limited to modern browsers, and the README says it is mainly aimed at presenting from your own laptop
- The README says it may not help if you have nothing interesting to say, and it offers no visual editor in the core project
remark
- Targeted at people who know HTML and CSS, so it is not a point-and-click tool
- PDF export styling is not guaranteed to match the browser view
- The README's boilerplate loads resources from remote URLs, so an internet connection is typically needed unless you build locally
