 **10 second pitch:** Libreddit is a portmanteau of "libre" (meaning freedom) and "Reddit". It is a private front-end like [Invidious](https://github.com/iv-org/invidious) but for Reddit. Browse the coldest takes of [r/unpopularopinion](https://libreddit.spike.codes/r/unpopularopinion) without being [tracked](#reddit).

 Libreddit hopes to provide an easier way to browse Reddit, without the ads, trackers, and bloat. Libreddit was inspired by other alternative front-ends to popular services such as [Invidious](https://github.com/iv-org/invidious) for YouTube, [Nitter](https://github.com/zedeus/nitter) for Twitter, and [Bibliogram](https://sr.ht/~cadence/bibliogram/) for Instagram.

 If you are looking to compare, the biggest differences I have noticed are:
 - Libreddit is themed around Reddit's redesign whereas Teddit appears to stick much closer to Reddit's old design. This may suit some users better as design is always subjective.
