Give it the URL of a Reddit thread and it checks archived data for comments and posts that are no longer visible normally. You can search Reddit posts and comments using things such as the subreddit, author, date, and text without downloading enormous datasets yourself. A lot of older guides to recovering Reddit posts were written before Reddit changed access to its API in 2023. As of 2026, Reddit says developers must request and receive explicit approval before accessing Reddit data through its API. In other words, tools built around Reddit data can break when Reddit changes something underneath them — which is exactly what happened to Reveddit's website.
