Warning
Copies of this app are going around. Renamed builds are handed out and sold as other people's launchers, with no source code and no credit. The real Dota 2 Mod Manager is free, has no paid version and never asks for your Steam login. Do not trust a launcher that shows no source code, names nobody it is built on, wants a subscription or a payment, or makes you sign in. How to tell the real one.
The app, the site and the docs all live in dota2-mod-manager. Write to hello@dota2modmanager.com, or security@dota2modmanager.com for vulnerabilities.
