Tool Open source
Bento is an open-source PowerPoint alternative and office suite distributed as a single HTML file. Each deck contains its own viewer, presenter, editor, fonts, images, charts, animations, and readable JSON document data, so it can be opened, edited, presented, and shared in a modern browser without an account, installer, or network connection.
The editor rewrites the deck's data block when saving, using the File System Access API with a download fallback. It supports morph presentations in which elements sharing an ID animate between slides, built-in bar, line, pie, and scatter charts, speaker view, comments, layouts, interactive states, motion paths, PDF export, and multiple interface languages. Optional collaboration uses end-to-end encryption with AES-GCM, a CRDT for merging offline edits including character-level text changes, and a relay that stores ciphertext rather than document contents; Offline mode blocks synchronization and collaboration.
