How many heroes are in Dota 2?

On patch 7.41f — 127. By primary attribute: Strength — 36, Agility — 35, Intelligence — 34, Universal — 22.

How do I find out who counters a hero?

Open the hero’s page: it shows who is strongest against them, who they beat and their best partners at every rank, plus the build by position. For an answer to the whole enemy draft, use the draft helper.

How often is the data updated?

We count public matches at every rank: hundreds to thousands of games for every hero pair. We refresh the data after each patch once it has a week of matches, and at least once a month.

Every hero, as in the game: who counters it, who it beats, who it is stronger with and the build by position — start, boots and items through the game.
