I understand the feelings of despair, but the rest of the internet is still very much out there. There’s a growing and dedicated movement to take it back from corporations. I’ll link a few of the neat little websites I’ve found on Neocities and in various other places.
https://sadgrl.online/ - A good jumping-off point that has html guides, links to webrings, and other cool stuff.
https://deathgenerator.com - You ever wanted to make one of those funny fake video game screenshots, but you don’t have the patience to do the image editing? Well, here you go!
https://signal.vercel.app/edit - A neat little free online midi editor! You can upload midi files or compose your own!
https://dan-ball.jp/en/javagame/dust/ - A cool falling-sand-type game. The website it’s hosted on is full of other cool games, most of which are free and don’t require flash (rip flash)
https://webshark.neocities.org/gamepages - Speaking of games that don’t require flash, here’s a whole page of ‘em. Most are fairly simple, but they’re still a lot of fun.
https://ocremix.org/ and https://vgmusic.com/ - Two websites that have been around since almost forever. OCRemix is home to video game music remixes, and VGMusic has a MASSIVE library of video game midis! I used to spend a lot of time on VGMusic in particular when I was a kid.
https://cooltext.com/ - You can make cool-looking text! They also have free fonts you can download.
And this is by no means a comprehensive list, no. This is just a sampling. There’s so much out there just waiting to be discovered-- you just have to go looking for it! (And remember, kids, be careful out there-- computer viruses and malware are still very much a threat, so I encourage you to get uBlock Origin or NoScript-- or both-- for your web browser before you start web surfing! Also never give out any personal information! And for the love of all that is good, and for your own safety, please stay away from the porn sites if you’re under the age of 18.)
Have fun, stay safe, and
