Show HN: Bento – An Entire PowerPoint In One HTML File (Edit+view+data+collab)

Bento is a new web-based tool that enables users to create, edit, view, and collaborate on an entire PowerPoint presentation within a single HTML file. Developed over the past few months, it aims to simplify slide deck management by eliminating the need for separate files or external software, supporting real-time collaboration directly in the browser.

The developers behind Bento have built a system that embeds all presentation data, slide content, and interactive features into one self-contained HTML document. This approach allows users to open, modify, and share complex presentations without relying on traditional presentation software like PowerPoint or Google Slides. The tool supports editing features, data integration, and collaborative editing, all within a single file. According to the project’s documentation, Bento leverages modern web technologies such as HTML, CSS, and JavaScript, and is designed to be lightweight and portable, making it easy to distribute and use across different devices and platforms.

While the project is still in development, early demonstrations show that users can perform basic slide edits, add data-driven elements, and collaborate in real time. The team reported that their goal is to address common pain points associated with traditional slide software, such as file versioning, external dependencies, and limited collaboration features. The approach also aims to facilitate embedding presentations into websites or internal tools, streamlining workflows for teams that rely heavily on slide decks.

Implications for Presentation Creation and Collaboration

Bento’s approach could significantly impact how teams create and share presentations by reducing reliance on proprietary software and simplifying the collaboration process. Since all presentation data resides in a single HTML file, sharing and version control become more straightforward, especially in remote or distributed teams. This innovation could also influence the development of web-native presentation tools, encouraging a shift toward more lightweight, portable, and integrated solutions that work directly within browsers.

Web Technologies Transforming Presentation Tools

In recent months, there has been increased interest in using web frontend technologies to build more flexible and accessible presentation tools. Projects like Claude Code have demonstrated the potential for coding harnesses to enhance slide decks. However, a common challenge has been enabling easy editing and collaboration without complex setups or multiple files. Bento addresses this gap by encapsulating all presentation components into a single, portable HTML file, aligning with broader trends toward web-native document management.

This development follows a pattern of lightweight, browser-based solutions gaining popularity as organizations seek more flexible and integrated workflows. The project’s emphasis on collaboration and data integration reflects ongoing efforts to make presentations more interactive and adaptable in a remote work environment.

“Our goal was to create a seamless, portable presentation experience that eliminates the need for multiple files and external software.”
