To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it.
Open it in a browser and then you can edit, present, print and save. Share it via email or via Airdrop and all they need is a browser to edit, present and also do live collab on the slides. Drop it in to Claude or ChatGPT to transform existing pptx files into Bento slides. There is no cloud involved, only an encrypted blind relay to allow for shared editing. The relay doesn't see any of the data.
Check it out at https://bento.page/slides/ which takes you straight to the editor.
Go to https://bento.page/guestbook/ to try out the live guestbook to experience share editing / collab.
There is also a gallery with some sample decks on the website - https://bento.page/
All the code is MIT licensed and you can find it here - https://github.com/nyblnet/bento . I used reveal.js with several other libraries (including some homegrown ones), and Claude Code.
One note: The home page says "Nothing phones home," but the Bento files I've examined include a cloudflareinsights.com beacon.
Agreed that the homepage should not indicate otherwise, but on the plus side with a tool like Bento you can edit the HTML file locally, remove the script tag at the bottom that does that, and never worry about that tracking again!
Will keep chipping away at this and update as I learn more.
Because while cool this is clearly heavily vibe coded.
Bento works with a predefined schema, so you cant use any HTML library (Such as Mermaid.js) if you need it in your presentation.
But then again, often you dont need it.
Just created a presentation with Bento... I do think Reveal.js gives you more raw power. But I like bentos single html page design, and you can easily edit it manually. You cant do that with Reveal.js
Great work! I hope to see more and more apps like this in the spirit of "Toss it all into context"
