Hi, I'm the creator of Bento. Just wanted to share a bit more about how I created it beyond what's in Github. The file contains more or less two sections. There is a plain block of JSON near the top of the file which is the slide data. You can read, grep, or point a harness at it. The app itself is in a base64 blob that loads through a small shim which deflates in the browser with DecompressionStream, which keeps the…

This was my biggest question. Thanks for preemptively answering (and being proud!).

When I was playing with this, I immediately thought of TiddlyWikis, which I've always been fond of, but they never took for me. However, an easily editable presentation -- that's a use case I can understand.

I couldn't see how there was a CDRT when I'm just working with a single file. I was trying to figure out where the server was. So -- this is just on for everyone? Are you concerned that your Cloudflare account will be hammered with this?

You can play around in the guestbook. I'm in it right now and you can see me editing things.

Cloudflare Durable Objects are pretty cheap and I'm using it like a very basic pub/sub with each deck having it's own DO. I did some calculations and it should be well within my spend limits.

Great job! How long did this project take total? How much percent is AI generated?

Thanks! I started on this last week in my spare time and I used Claude, all my commit history is on Github. I did most of the coding via Claude Code, no fancy system or exotic harness.

I would love to do more by hand, but I look after a tech team inside a renewables firm, so I don't have much time between job and my preschooler.

Are you kidding me? I gave it a spin, and it's solid. That's crazy, I'm impressed!
