 # dozzle
 
 Dozzle is a log viewer for Docker. It's free. It's small. And it's right in your browser. Oh, did I mention it is also real-time?
 
 While dozzle should work for most, it is not meant to be a full logging solution. For enterprise use, I recommend you look at [Loggly](https://www.loggly.com), [Papertrail](https://papertrailapp.com) or [Kibana](https://www.elastic.co/products/kibana).
 
-But if you don't want to pay for those service, then you are in luck! Dozzle will be able capture all logs from your containers and send them in real-time to your browser. Installation is also very easy.
