Wox
Wox is a full-featured launcher for Windows, which makes it easy to quickly search the web by tapping just a few keys on your keyboard—whether you want a simple Google search or would rather use your own customized prefixes to load your query in a different search engine.
Wox also supports third-party plugins, so you can do everything from find out your current IP address, to searching YouTube and Twitch streams, to controlling your Spotify playlist.
Wox is free for use and open-sourced at Github, Try it now!
