One place for every tool

Build the Warcraft III setup that fits you.

W3Booster is an app workspace, not one fixed overlay. Choose what you use, keep each app’s settings together, and open the right surface for play, observation, or broadcast.

01 / APP LIBRARY

Install the experience you want.

Discover official and community apps, see what each one adds, then install, enable, or pause it without rebuilding your streaming setup.

Every app has its own settings and surfaces. Disable an app without uninstalling it, or pause stream and in-game integrations globally.

03 / LIVE CONNECTION ⌁

Ready when Warcraft III is.

The desktop recorder follows match state, while apps receive normalized data for players, resources, heroes, upgrades, statistics, and more.

See the match, not just the fight.

Match Vision turns live data into context for players and viewers: identities, rankings, resources, heroes, abilities, inventory, research, match score, and game time.

Made for broadcast

One browser source. Every enabled overlay.

Add W3Booster to OBS once. The platform loads the overlay apps you enable, keeps credentials out of those apps, and gives each app only the match data it needs.
