Reddit is finally rolling out a top requested feature among users: native dark mode. In a blog post, the company said the desktop Night Mode theme is now available to everyone after being rolled out to employees for testing a few weeks ago. Night mode offers users a black theme rather than the classic white, and is an option well suited to those who enjoy browsing late into the night.

Reddit notes that Night Mode already exists in its native mobile apps and the old desktop webpage (via the Reddit Enhancement Suite browser extension). The company’s first site redesign in a decade began rolling out last month, with a native Night Mode listed as a “what’s next” feature for the days ahead.
