Bento

The dominant product discussed in HackerNews comments is 'Bento' — an HTML-based presentation tool that bundles slide data (plain JSON) and the application itself (base64-compressed blob with DecompressionStream) into a single self-contained HTML file. The creator actively participated in the thread, explaining the architecture and acknowledging bugs. USER SENTIMENT IS OVERWHELMINGLY POSITIVE about the concept: users describe it as 'amazing,' something that 'blew my socks off,' and draw favorable comparisons to TiddlyWikis for its self-contained philosophy. Key technical praise: the single-file output is easily shareable, grep-able, and manually editable — something users note Reveal.js cannot do. The original compressed size was ~1.3MB. However, CONCRETE BUGS WERE REPORTED: (1) During live collaborative editing on the guestbook demo, focus was lost on every incoming update, making it difficult for two users to work simultaneously; (2) The slideshow state was too aggressively persistent — reloading and navigating caused it to resume at the wrong slide rather than respecting the user's current selection; (3) Swiping past the first slide dropped users back into the editor unexpectedly. A significant FUNCTIONAL LIMITATION noted by a Reveal.js user: Bento uses a predefined schema and cannot embed arbitrary HTML libraries (e.g., Mermaid.js), trading raw power for portability. The creator acknowledged the collab focus-loss issue and committed to fixing it the same night. A secondary, UNRELATED 'Bento' project (a DIY cyberdeck computer using Steam Deck OLED internals under an Apple Magic Keyboard with XR glasses) appeared in the same comment set — this is a completely different open-source hardware project, not the presentation tool. Multiple users discussed XR glasses (Viture Pro) limitations: blurry edges, IPD issues, insufficient sharpness at 1080p for replacing a desktop monitor, though praised for gaming and movies.
