Big is a presentation system that emphasizes simplicity and speed for developers and creative professionals making focused talks.
The tool solves presentation procrastination by removing configuration overhead and design decisions. Rather than spending time tweaking fonts and layouts, Big uses a configuration-free approach with CSS Grid-based slide layouts that automatically size text to fit the screen. Presentations are written as HTML divs, allowing any text styling or additional elements to be added directly. Speaker notes are placed in a notes element and appear in the browser's developer console, which can be displayed on a separate screen during delivery. Navigation works through arrow keys, clicking, or swiping on touch devices.
Big suits developers and designers who want to create presentations quickly without fiddling with presentation software. It works well for Takahashi-style talks that rely on large text and minimal content per slide. The entire system is lightweight at around sixteen kilobytes. The tool can be used by opening an HTML file locally or deployed via GitHub Pages or any web hosting service. Themes are customizable through CSS, and the system supports multiple viewing modes: talk mode shows one slide at a time, print mode displays two slides per page with speaker notes, and jump mode shows many slides per page for quick navigation.
Development activity shows consistent maintenance with regular commits addressing bug fixes and feature refinements. The project maintains a focused scope, resisting feature creep while responding to user-reported issues. Documentation is thorough and includes practical examples for common use cases like code display and custom backgrounds. The maintainer actively engages with community contributions and keeps dependencies minimal to preserve the tool's lightweight nature.
