 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.
