what is rosintplus.github.io fr?

Rosint+ is a browser based tool for looking up a Reddit user's full posting history, including content that has since been deleted, comments that were removed, and posts from accounts that have been made private. It is a fork of an existing project called rosint.dev, extended with extra features such as profile statistics, the ability to save profiles for later, several visual themes, and support for multiple languages. To find this history, the tool queries two separate public archive services, Arctic Shift and PullPush, at the same time, then merges their results together and removes duplicate posts or comments using each item's unique ID. Search results are split into a posts tab, showing title, subreddit, score, and a snippet of the body text, and a comments tab showing the full comment text with a link back to the original discussion thread. Results can be filtered by date range with a calendar picker and are paginated in batches of 100 using a timestamp based cursor. Features added specifically in this fork include a profile analytics panel that shows a user's most active subreddits, a heatmap of their posting activity with an estimated timezone, and their most commonly used words. It also lets someone pin profiles they want to revisit and keeps a history of recent searches. The interface ships with nine color themes, each available in light, dark, and automatic modes, and is translated into seven languages. Results can be exported as a CSV or JSON file, and a single click copies a permalink along with its timestamp and other details. The whole tool runs entirely in the browser with no backend server, database, or login required. The README notes that since it depends on two third party archive services with no uptime guarantee, results may be incomplete if either archive is missing data or if both happen to be down at the same time.
