Bento

What is Bento?

Bento is a privacy-friendly, open-source office suite that ships as a single self-contained HTML file. It bundles a slide editor, a word processor, and a spreadsheet tool into one app that runs entirely in the browser, with no server, no account, and no tracking.

Slides without the bloat

Bento's slide editor is the headline feature: a clean, modern deck builder inspired by tools like Pitch and Notion, with smooth animations, easy layout, and inline media. It is designed to feel lightweight while covering the everyday needs of pitch decks, internal presentations, and slide-based storytelling.

A whole office in one file

Beyond slides, Bento includes:

• A document editor for long-form writing
• A spreadsheet tool for quick data work
• A local-first data model: everything you create lives in your browser's storage or in a .bento file you can save, share, and open anywhere

Why choose Bento over PowerPoint?

• Truly open source under MIT, with no premium tier gating features
• No cloud lock-in — your files are just HTML, so they are portable and future-proof
• Privacy by default — nothing leaves your device unless you choose to share it
• Single file — share a deck by sending the file itself; no signups, no installs for viewers
• Modern UX — built with contemporary web tech instead of decades of accumulated PowerPoint features

How it compares to PowerPoint

Bento is not aiming to be a 1:1 PowerPoint replacement. It skips the heavy feature surface (deep animation timelines, VBA macros, complex master slides) in favor of speed, simplicity, and a single portable file. For everyday presentations, internal decks, and privacy-conscious teams, that tradeoff is the whole point.
