bento

bento is an office suite that packs data, viewer, and editor into a single local-first HTML file.

Bento provides office documents as single HTML files containing data, viewer, and editor together. Users can build presentations with animation, video, live charts, and embedded fonts without creating an account or using the cloud. The platform supports AI agents such as Claude Code, Cursor, Aider, Ollama, Cowork, Codex, and Gemini to edit documents directly via JSON blocks or attached files. It offers end-to-end encrypted live collaboration and offline functionality. The software is open source under the MIT license with no telemetry or tracking.
