Web Development
Webhosting / Platforms
Neocities - My site is hosted there! I've also heard good things about Nekoweb, which is a popular alternative.
Porkbun - This is where you can buy/manage domain names! I heard they're very reliable. Make sure you buy one that renews for cheap, fair warning.
carrd - A site builder that's very user-friendly and easy to understand. It was a good starting place for me, before I had the courage to make my own web page.
Pika - A neat, minimalist looking blogging site. You can also use it as a personal site by making extra pages, and there's even a guestbook you can opt into that lets people send you drawings!
Tools
Phoenix Code - A pretty good text editor for web stuff, and it has live preview!
optiPNG - You can run images through this optimizer, shrinking the file size without losing quality. Helpful for people with slow connections!
Coolors - An unnecessarily bloated colour palette generator.
CSS Stripes Generator - Make some cute stripes!
cOOl & EMO tEXt cOnVERTer xXX - Just like the good old days.
google webfonts helper - A convenient way to optimize fonts on your site... maybe? I'm not sure, but maybe you'll start using this?
Add-ons / Widgets
FC2 Hit Counter - Lots of old-school counters to choose from, to track unique viewers. They're all very cute!
status.cafe - If you're looking for an easy way to embed status updates to your homepage. Keep in mind that it might take a couple of days to get your activation link, so be patient.
Ayano's Guestbook Widget - This is what tons of people use for comments. It's all done through google sheets, so it's a bit of a hurdle to get it set up, but the instructions are easy to follow.
komments - An another comment widget. You can embed this on your site through an iframe, or just have it as a separate page. It's easier to get it set up, but you can't customize it as much.
Zonelets - I'm the one nutcase who actually uses this thing. It's been a good starting place for me, especially as someone who didn't know what they were doing. You can use Zonelots if you prefer, which is an expansion with an added tagging feature.
frog tab - This was intended as a private little to-do list and task reminder, but you also can turn it into an askbox by following this tutorial!
