In no particular order...
Tools and Other Useful Things
JellyNeo
Most useful tool for Neopets. It has news, resources, information, guides, clickable dailies, and much more. It is always the first bookmark on any computer I have.
JellyNeo's Item Database
Price tracking for every single item in Neopia. Has a wishlist feature you can exchange with other users and so you can monitor prices. Warns you of inflation. Also has checklist tools.
Dress to Impress
Try out items on your Neopet and dress them up to see if you *actually* want that wearable before you buy.
The Lost and Pound
Look at pets who are lost in the pound due to having glitched petnames. Currently, the index doesn't work properly so you'll have to manually add /neopets/bori (or whatever type of pet you are looking for) to the URL. Also has a petpage
SunnyNeo
Really cute site with tons of information. Has really nice free layout templates for Pet Pages, User Lookups, Shops and more.
NeoColours
A helpful tool so you can decide what color/species you want your Neopets to become.
NeoMallers
Get yourself a hit counter for your shop, also has a robust sales history tracker.
The Neopets Subreddit
I hate Reddit but everyone here is very nice and willing to help you if you have any questions. They will usually discuss news, updates, and their strategies in playing the game. The Discord server is also a good resource.
Food Club
Neofood.club
Input betting strings from betpages to make your daily Food Club inputs a total breeze. Here's a guide if you are feeling overwhelmed.
Boochi's Bets
One of the users I use, this is the one I like to use for the most part. It's important to stick to one user and this one is really reliable in their daily uploads.
Lefty's Food Club Bets
Another user I use who always places bets daily without fail. : )
Pet Pages
Quality Petpages
Outgoing links (within Neopets) of over 500 high quality Petpages.
Ciel's Screenies Page
A happy little page where Ciel draws over screenshots she plays of the game and describes her pets adventures.
Zapping Your Dream Pets
ZYDP maintains a public wishlist. They use their lab rays to zap Neopets, and then they adopt out the pet to someone who wished for a pet with that color/species combination.
MOON
(UFA) Up for adoption and dream pets directory!
Achievable Trophies
A petpage with guides on user lookup trophies and how to get them.
