This is amazing. I also think this will become more common. I feel there is a lot of software that can just be served locally via html/typescript/react etc and even have local state. There's just not been an economic incentive till now.

I am personally using kimi k3 to create a mobile friendly set of games, starting from math like linear algebra to quantum physics - neurodivergent friendly, completely local state, served from github pages - to get someone interested in the field. This needs an economic incentive to exist without LLMs, because of so much different expertise needed, and time.

if anyone's interested in the games let me know - i plan to play it myself, improve it, remove bugs etc before publishing on HN.

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…

I would call this a slide show not powerpoint mostly because making it work with the satanic office formats is a path to hell.

Hopefully simpler formats like this will become the norm and the old ones can die.

Very cool project! It looks nice and the technical aspect of how sharing/CRDT is implemented is a really great idea! I would definitely be interested in the ability to change the relay; ideally to something self-hosted.

Thanks! That's a really good point. I used Cloudflare DO as it was elegant and convenient, but no reason why we can't run a small daemon to handle the same. I'll work on this later in the week.

> Go to https://bento.page/guestbook/ to try out the live guestbook to experience share editing / collab.

My M1 Mac froze in the end (had to hard-reboot), but that was so much fun! I guess there’s a reason Figma uses WASM and a custom renderer, though I guess your implementation should work fine for most cases (i.e. not when all of HN are trying to edit everything simultaneously :^)

Two notes:

1. It would be nice if another person changing something unrelated to what I’m doing didn’t reset the focus for me.

2. WAY too llm-y copy both on the landing page and the example deck. Your HN submission text is way easier and more pleasant to read.

And huge kudos for releasing this as FOSS!

Thanks! I had to reset the guestbook because it's being spammed. It's on epoch 4 now, hopefully people will be better behaved moving forward!

1. Yes, that's a good point that somebody else raised also. It went pass testing as I was only testing with 1 or 2 other people at once. Will fix this tonight.

2. Yeah, agreed and fair point. But I don't write well and I don't have time between day job and being a dad. Will try to fix this gradually.

I recently did something similar with just asking claude to create me a presentation with GSAP animations. With a some nice features to embed apps, switch the language while presenting, etc. - it works like a charm: https://eos-lci.gitlab.io/eos-lci-presentations/klimabuendni... (all open source)
