It's not obscure, but, for me, Wikipedia is the ultimate example of the old internet that still persists today.

Free to use, no account required, ad free, non-corporate, multilingual, heavily biased toward text, simple and utilitarian design. Hyperlinks concatenate relevant pieces of information, which serve as the means to navigate the site. The code is very simple (seriously, view the page source of a wikipiedia article). It's based on the human desire to learn and share knowledge with others, and has remained resilient to corruption by commercial interests that pervert that desire for monetary gain. It's a beautiful thing.

4-ch.net (not to be confused with 4chan) is a 90s BBS that is still online and occasionally active. It's neat to see posts from the 90s still on the front page.

wow nobody mentioned https://www.lingscars.com/

Sites that have old forums. There aren't many anymore, but ones I've seen that have been very helpful of late include car sites, a timeshare forum, and the Fantasy Grounds forum (my virtual tabletop of choice).

I'm sure there are others out there, but it's definitely more rare than it used to be. Is Something Awful still around?

I imagine their source code is such an unmaintainable mess that it’s impossible to modernize

Aw i miss when website tracking was only "xxxx users have visited this page" and it was just a simple counter that counted up.

Some examples that I remember are:

• The Berkshire Hathaway's website (https://berkshirehathaway.com/)
• The UNIX website (https://unix.org/version4/)
• Xorg Project website (https://www.x.org/wiki/)
• Marginalia Web Search (https://search.marginalia.nu/)
• W3C (World Wide Web Consortium) pages containing Standards (e.g.: https://www.w3.org/TR/controller-document/)
• Pd (Puredata) Project Website (https://puredata.info/)

https://www.spacejam.com/1996/jam.html

I’m pretty sure spacejam.com showed that page up until the sequel supplanted it.

Debian’s website….

https://everything2.com/node/e2node/An%20Introduction%20to%20Everything2 - massively interlinked information site

https://www.dieselsweeties.com/ - robots and people comic

https://realultimatepower.net/ - ninjas

The APRS website hasn't even started using HTTPS yet.

Zombo.com

LaserDisc Database

Extremely useful website for collectors of dead media formats (LD, D-VHS, HD-DVD, CED, VHD, etc.) Still has an old style interface with priority given to function and utility over styling. Also has a storefront where you can buy and sell discs.

Really awesome old school sites. Crazy gifs, web rings, etc.

I haven’t visited in a long time – but I can’t imagine Craigslist has changed much.

Kernel.org, home of the Linux kernel, hasn't changed much.

Kernel.org today:

Kernel.org in 1998:

No JavaScript sites on onionland

If you want one that isn't actually from that time, just feels like it, I'd say https://tildes.net/

https://search.marginalia.nu/ is a search engine for non-commercial content and is pretty great regarding the old-school factor :-)

My healthcare services websites. Their website and mobile app require separate logins. The website logs in then redirects to a completely different website.

They have a tax-free “store” that feels like a completely different website.

Everything is laid out using what seems like the idea of middle management and not modern design philosophy.
