Sling TV, a popular tool for watching live television without a cable subscription, is finally opening its doors to people who don't want to download an app. The service is now open for anyone through the use of a web browser, making it simple for people to log into their Sling account and watch what they're looking for.

There are a few features missing from Sling, including the DVR feature that currently resides in the mobile and Windows 10 apps for the service. The browser version of Sling currently holds most of the service's core functionality, primarily the ability to watch Live TV as long as you have an account.
