Bento packs slide editor and live collab into single HTML file

Bento is an open-source presentation tool that packages slide editing, viewing, animations, and real-time collaboration inside a single, self-contained HTML file (~560 KB) without requiring cloud accounts or installation. It features end-to-end encrypted multi-user editing via a blind relay, offline-first operation, and support for converting presentation files using LLM coding harnesses like Claude Code or ChatGPT.

// ANALYSIS

Bento delivers an exceptionally slick, privacy-conscious alternative to Google Slides and PowerPoint by embedding the entire authoring environment into a standalone web document.

* Retains the convenience of modern real-time collaboration without requiring cloud vendor lock-in or user accounts.

* Built on reveal.js and standard web tech, making slide decks easy to parse, modify, and generate using AI coding assistants.

* Offline-first architecture with a modest file footprint (~560 KB) guarantees long-term durability and instant load times.
