MDX Deck review
A developer-focused deck builder for React-based presentations in the browser.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MDX Deck is an open-source presentation tool for developers and technical presenters who want to define slides with Markdown and MDX. Presentations run in a web browser through a command-line development server, while React component imports allow interactive or reusable elements inside decks. Custom themes, slide layouts, speaker notes, overview mode, and grid mode support structured technical presentations. It is aimed at users comfortable with JavaScript, React, and developer-oriented workflows rather than nontechnical slide-authoring teams.
Its strongest distinction is the connection between presentation authoring and the React ecosystem. Developers can bring React components into presentations, then shape the visual system with custom themes and components. Custom layouts add control over slide structure, while the zero-config command-line interface keeps the authoring model focused on project files and code. Presenter mode adds a practical delivery layer with next-slide preview, a timer, and speaker notes. This combination suits technical talks, product demonstrations, and engineering documentation that benefit from reusable components and code-defined slides.
The trade-off is a narrower workflow than general-purpose presentation software. The product is web-based and developer-oriented, so teams seeking a visual editor, collaborative authoring, mainstream presentation imports or exports, or broad third-party integrations should choose a tool designed around those needs instead. MDX Deck is a better fit for an individual React developer or technical presenter who values code-based control and an open-source MIT-licensed project. It is less suitable for nontechnical teams that need shared editing, conventional office-document workflows, or a presentation system independent of JavaScript and the command line.
