I ask because the dev tool that our company creates occasionally (okay, very rarely) gets a question about offline mode, and when I prod, it's usually just out of curiosity, not because they actually need it in real life.
Browsers'history sucks. I don't know if this project does this, but I would absolutely love to be able to do SQL queries on my browsing history.
I have 'lost' many websites I remember visiting, but for which I didn't remember anything in the title.
Also, obviously, websites change sometimes, and the web archive might not have cached the website you visited. Although from what I can tell, this project doesn't version websites, it just caches the latest, so you would probably just overwrite the previous version accidentally.
Increasingly ≠ totally.
Even though I'm a developer, pre-pandemic I would have to spend a day or three offline several times a year while working. This would be useful for that.
I know an IT guy who works in mines. He loves anything that works offline.
It's a concern I have every time I find a particularly interesting independently hosted blog post or article.
The Internet Archive goes a long way towards making me worry about this less, though. (Let's just hope they don't go away!)
You can have archives from x day or x week or whatever, organized yourself, versioned with git, as you like, to save web content through version changes, removal or vanishing.
