What Is PoE Ninja?
poe.ninja Analytics platform · third party · free
A free, independently built website that tracks prices and character builds in Path of Exile and Path of Exile 2. It reads public data the games publish, then organises it into economy overviews showing what items sell for, and build overviews showing what top ladder players are running.
It is not a game, not a marketplace, and not made by Grinding Gear Games.
The problem it exists to solve
Path of Exile has no shops, no fixed prices and no auction house. Everything an item is worth is worth because another player will pay it, and that consensus moves constantly — sometimes within hours of a league starting, sometimes within minutes of a patch note landing.
That leaves a genuine problem. Before you can trade sensibly you need to know roughly what things go for, and there is no official source that tells you. The same applies to builds: the game gives you a passive tree with over a thousand nodes and no indication which combinations actually work.
That gathering is what the platform does. It reads what players have listed for sale and what the highest-ranked characters are running, then presents both as something you can read in a few seconds instead of reconstructing yourself.
What is actually on it
The exact sections change as the games change, but they fall into a few consistent groups. Whichever version you land on, you are looking at one of these.
Currency and exchange rates
What each orb trades for against the others, which is the backbone every other price on the site is expressed in.
Unique items
Named items with fixed properties, priced individually. Variants, corruptions and roll ranges are usually listed separately because they are separately valued.
Cards, fragments and crafting materials
Divination cards, map fragments, essences, scarabs and the rest of the consumable economy, each with its own overview.
Build overviews
Characters from the ladder, filterable by class, ascendancy, main skill, keystone or equipped unique, with their trees and gear visible.
Historical graphs
How a price has moved across the league so far, which tells you where something has been rather than where it is going.
Character export
Any listed character can be exported as a code and opened in Path of Building, which is where its damage and defences can actually be examined.
Where the numbers come from
This is the part almost nobody explains, and it is the part that determines what you can trust. The economy data and the build data come from two entirely different sources, with different coverage and different blind spots. Treating them as one thing is where most misreadings begin.
- Source
- The public stash tab API, which publishes every item a player has put in a tab marked for sale.
- Sees
- Asking prices. What sellers have listed things for, not what buyers actually paid.
- Processing
- Price-fixed listings and statistical outliers are stripped out, and what remains is reduced to one representative value.
- Blind spot
- Anything traded privately, in bulk off-platform, or never listed at all. Thinly listed items produce unreliable values.
- Source
- The official ladder API, which returns ranked characters for each league.
- Sees
- High-ranked characters only. Class, ascendancy, tree, gems and equipped items for those it returns.
- Processing
- Characters are grouped by skill and ascendancy to produce the popularity figures shown on overviews.
- Blind spot
- A hard cap of 15,000 entries in Path of Exile and 1,000 in Path of Exile 2. Everyone below that is never returned.
Those caps come from Grinding Gear Games' own developer documentation, not from a choice any tracker made. No third-party tool can see past them, which is why the overwhelming majority of characters never appear in a build overview anywhere.
What it costs and what it wants from you
Nothing, and nothing. There is no account, no login, no download and no paid tier. You open a page and read it.
That matters more than it sounds, because a great many sites in this space do want something — an account link, an API key, a launcher install. Nothing that only reads public data needs your credentials to do it. If a site claims otherwise, that claim is the thing to examine, not the feature it is attached to.
Who built it
It is an independent community project rather than a company product, and it is not made by, run by or endorsed by Grinding Gear Games. GGG make the games and publish the data; the platform reads that data and organises it. Those are two separate things done by two separate parties.
Untangling the similar names
Three names in this space look alike and get confused constantly, including on this site, whose own domain is close enough to warrant saying so plainly.
If you need current prices or ladder builds, you want poe.ninja. If you need help with your account or the game, you want Grinding Gear Games. This site explains how to read what you find on the first one.
What it cannot do
Knowing the limits is most of knowing how to use it. Five things it is not built to handle, none of which are faults.
- It cannot process a trade. It is a reference. Buying and selling still happens through the official trade site or in game.
- It cannot predict a price. Every figure and graph describes the past. Nothing on the page carries information about what happens next.
- It cannot see most players. The ladder cap means the visible sample is the top of the game, not a cross-section of it.
- It cannot tell you what something sold for. The stash data is asking prices. A listing that nobody buys still counts toward the figure.
- It cannot judge a build. Popularity is a count of what people are running, and a count is not a recommendation.

Where to go next
Knowing what it is gets you to the front page. Knowing how to read it without being misled by a confident-looking number is the harder half.
