RareScanner is an addon for World of Warcraft that includes a group of tools to help you track rare NPCs, treasures and events while you play.
The notable tools that RareScanner includes are:
Alerts from nearby rare NPCs/treasures/events
This is the main feature of RareScanner. The addon displays a button in the middle of the screen with information about all the entities detected nearby. Around the button information related to the entity is displayed, such as a miniature (in the case of an NPC), the name of the entity and the loot that you could obtain after killing/collecting it.
World map information
RareScanner adds icons of every rare NPC, treasure and event that it tracks to your worldmap. When you hover your mouse over these icons you will get extra information in a tooltip.
It also shows all the spawning spots for every tracked entity and for some entities it also adds some guidance icons to help you reach to its position, force its spawn or unlock it.
You can customize all the information displayed in the map and the tooltips from RareScanner options panel.
Rare NPCs explorer
RareScanner is designed to help you track every rare NPC/treasure/event in the game, but usually you will be more interested in finding NPCs that drop useful loot, like missing mounts or pets that you want to add to your collection.
While you can use the world map to check the loot of every NPC/treasure by hovering the mouse over their icons, it will take a lot of work to find exactly those missing items, so here is where the explorer comes in handy.
RareScanner allows you to add your own NPCs (even if they aren't rare), so you can get alerts whenever you pass by them.
Out of the box RareScanner will be tracking every entity in the game, however you might be interested only in a few. Using the previous tools (the world map interface, the explorer, the button with the alert or RareScanner options), you can configure the addon to track only for what you are interested in.

Important notes for Dragon Isles.
1. Expedition Scout's Packs and Disturbed Dirt: These two treasures are every where. I added a new option under "Container filters" to avoid getting alerts for filtered containers while still showing them in the worldmap. By default these two treasures will be filtered and this new option will be enabled. I really advise against keeping them active because the addon will be alerting you to them constantly, so be aware. And if you don't want the icons in the worldmap either, disable that new option so they will be gone completely.
2. With the launch of a new expansion I need one or two weeks to collect all the loot tables for every single rare NPC, so in the first version (10.0.2.1) the most of rare NPCs don't have much loot available. For this reason, you shouldn't use the explorer to filter NPCs, because it will filter all the entities in Dragon Isles. If you do, use the "NPC filters panel" to reenable all of them.
3. Currently in Dragonflight there are a lot of non-elite rare NPCs without vignettes, so you will have to enable "enemy nameplates" to let the addon detect them. I don't know if this is intended or Blizzard will change it in the future. Also there are several rare NPCs that keep showing the star icon in the minimap after killing them This is definetly a bug in the game and they should fix it, so you should report the error so they fix it.
Tips for a better performance in Dragon Isles.
1. Disable tracking for world map vignettes if you aren't hunting rare NPCs and you don't fly yet. With this option disabled you won't get alerts of NPCs in the other side of the island, only of NPCs right beside you.
You can create the next macro to easily toggle this option depending on your interest.
2. Adjust the sensitivity to a more confortable value if you notice that the addon is too annoying.
