Third-Party Apps

Third-party apps are independently developed applications that let people use a platform's services through software not made by the platform itself. On Reddit, they were unofficial mobile and desktop clients—such as Apollo, Reddit is Fun (RIF), Sync, BaconReader, and Narwhal—that connected through the Reddit API to offer browsing, posting, and moderation experiences many users preferred over Reddit's official app. They were especially valued for cleaner interfaces, accessibility features for blind and low-vision users, and powerful moderation tools.

These apps became the center of Reddit's 2023 API controversy. When Reddit introduced high-volume API pricing, the costs made many third-party clients financially unsustainable: Apollo's developer reported a potential bill of about $20 million a year and announced the app would close on June 30, 2023, with Sync, BaconReader, and RIF also shutting down, while a few apps survived by switching to subscription models. The shutdowns sparked widespread anger over lost accessibility and moderation capabilities and helped drive the coordinated subreddit blackout, making third-party apps a symbol of the tension between platforms and the developer and user communities that build atop them.
