About Hearthstone Deck Tracker
An independent resource dedicated to the most popular deck tracking tool for Hearthstone players.
If you have spent any time playing Hearthstone competitively, you have almost certainly heard of Hearthstone Deck Tracker. Known simply as HDT among the community, this open-source Windows application has been a staple for Hearthstone players since the early days of the game. It runs as a lightweight overlay on top of the game client, giving you real-time information about the cards remaining in your deck, cards your opponent has played, and detailed match statistics that help you improve over time.
Hearthstone Deck Tracker is not just another utility. For hundreds of thousands of players worldwide, it has become an essential part of how they experience the game. Whether you are climbing the ranked ladder, experimenting with new deck builds, or streaming your gameplay on Twitch, HDT provides the kind of data-driven insight that can make a real difference in your win rate.
The Story Behind HDT
From a community side project to the most-used Hearthstone companion app.
The Beginning
Hearthstone Deck Tracker started as a community-driven project shortly after Hearthstone launched. Early Hearthstone players had no way to track which cards had been drawn or played during a match. Several developers in the community began building tools to solve this problem, and HDT quickly rose to the top thanks to its clean overlay design and reliable card tracking.
Rapid Growth
As Hearthstone grew into one of the most popular digital card games in the world, HDT grew with it. The HearthSim team took over active development, adding features like automatic deck detection, per-deck win rate tracking, and integration with HSReplay.net for replays and statistics. The GitHub repository attracted thousands of stars and a growing base of contributors.
Feature Expansion
HDT added a Twitch extension for streamers, a plugin system for community-built add-ons, mulligan guides powered by HSReplay data, and improved opponent hand prediction. These features pushed it well beyond a simple deck tracker into a full-featured companion app.
Battlegrounds and Beyond
With the introduction of Hearthstone Battlegrounds, HDT adapted to support the new game mode. The tracker added Battlegrounds-specific stats, hero tracking, and composition analysis. Today, Hearthstone Deck Tracker remains actively maintained at version 1.50.6 and continues to receive updates for every Hearthstone expansion and patch.
What Hearthstone Deck Tracker Does
A complete companion for competitive and casual Hearthstone play.
Real-Time Deck Overlay
Displays the cards remaining in your deck directly on top of the Hearthstone client. You can see at a glance which cards you have left to draw and plan your turns accordingly.
Opponent Tracking
Tracks every card your opponent plays, shows their hand count and remaining deck size, and can estimate the probability of them holding specific cards based on the current meta.
Match Statistics
Records your win rates per deck, per class matchup, and per game mode. This data helps you identify which decks perform best and where your gameplay could improve.
Plugin Ecosystem
Supports community-built plugins that extend its functionality. From advanced statistics displays to custom overlay themes, the plugin system lets you tailor HDT to your specific needs.
Players rely on Hearthstone Deck Tracker because it turns information that would otherwise require manual note-taking into an automated, always-accurate overlay. It is especially popular among competitive players and streamers who need to make fast, informed decisions during matches.
The Team Behind HDT
HearthSim and the open-source community that keeps HDT running.
HearthSim
Hearthstone Deck Tracker is developed and maintained by HearthSim, the same team behind HSReplay.net. HearthSim focuses on building data-driven tools for the Hearthstone community. Their work combines real gameplay data with practical tools that help players at every skill level.
The project is open-source and hosted on GitHub, where it has accumulated over 4,900 stars. Written in C# on the .NET Framework, HDT benefits from contributions by dozens of community developers who help maintain compatibility with new Hearthstone patches and expansions.
HearthSim has earned a strong reputation in the Hearthstone community for building reliable, well-maintained tools. Their commitment to keeping HDT free and open-source reflects a philosophy of giving back to the player community that supports their work.
What HDT Means to Players
A trusted tool that has shaped how players experience Hearthstone.
On Reddit’s r/hearthstone community, Hearthstone Deck Tracker is frequently described as “the best deck tracker” available. Players appreciate the depth of its feature set, the accuracy of its card tracking, and the fact that it remains completely free to use. For many, installing HDT is one of the first things they do when setting up Hearthstone on a new computer.
The tool fills a gap that Hearthstone itself does not address. While the game client provides basic information during matches, it does not offer the kind of detailed tracking and statistics that serious players want. HDT bridges that gap without requiring any manual effort from the player.
Some players prefer alternatives like Firestone for its more modern interface, or Track-o-Bot for its minimal footprint. But HDT’s combination of overlay quality, plugin support, and deep integration with HSReplay data keeps it at the top for most users. Blizzard has acknowledged that deck trackers like HDT are within the game’s terms of service, so players use it with confidence.
