Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness.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.

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.

There is no cloud involved, only an encrypted blind relay to allow for shared editing.
