Ask HN: Are vibe-coded self-contained HTML apps the future of personal tools?

I came across this post today - https://news.ycombinator.com/item?id=44937991 and also myself created https://htmlsync.io and wonder if there are other people who now choose to use vibe-coded self-contained HTML apps to replace other personal tools they were using.

Do you think these self-contained HTML apps in one form or another are going to replace most personal tools?

If not, what do you think is the big limiter?
