I’ve been playing Dota 2 for about a few months now, so I’m still very much a beginner and learning the game.

One of the biggest things I’ve noticed during this time is how complex counter mechanics in Dota 2 really are.

It’s not just hero vs hero matchups — it also includes how entire drafts interact with each other, how item choices can shift the game, and many counters that only apply under very specific conditions. Because of that, simply looking at win rates or individual matches often doesn’t really explain why something is a counter.

So over the past month or so, I started organizing and documenting these counter relationships in my free time and put together a small website to make them easier to browse. It focuses on things like:

Hero counters and being countered

Situational item counters

Simple draft-phase hints about overall lineup interactions

The counters on the site aren’t based purely on hero matchup win rates. They’re compiled from player discussions, guides, and shared experiences, and I’ve tried to filter out ideas that are clearly outdated. The goal is to help explain why a certain hero or item can be effective in specific situations.

That said, since this is mostly a one-person project that I work on outside of my day job, there are still plenty of heroes and scenarios that aren’t covered yet. Some counter explanations may also be incomplete or open to debate.

I see this more as a learning and discussion tool rather than a source of “correct answers,” so I’d really like to hear other players’ opinions and perspectives.

I’ve put everything here mainly for my own use and for a few friends: https://dota2.tools/

If you have any suggestions or disagree with something, I’d love to hear your thoughts. There’s also a Discord link on the site if anyone wants to give feedback or discuss ideas.
