What ScrollX offers
As opposed to hopping between nine separate imageboards, it folds its supported boorus — Rule34, Gelbooru, e621 and the rest — together with NSFW Reddit into one continuous scroller where images, gifs and animations advance by swipe or endless vertical scroll. The presentation is deliberately stripped back; the site bills the format as a TikTok-style swipe and gallery view, and the homepage's Start-browsing button opens the stream directly.
Deep links carry much of the navigation: each source has its own path — /safebooru.org, /reddit.com — that accepts the tag queries booru users already know, so an address like /safebooru.org?q=branch lands straight on matching art. Reddit material can be pulled by subreddit query or by individual username, handy for following one poster's NSFW output without the native app.
What streams past is whatever those communities already host: anime-style fan art, illustrations and animated gifs, much of it explicit — though Safebooru, a clean-art board, sits in the mix, so the feed is not uniformly adult. ScrollX presents itself as a viewer for those sources instead of a studio or archive of its own.
Use happens in the browser, and its maker has described the project on Reddit as a no-ads viewer; the flip side is that coverage and tag quality belong to the source boards, not to ScrollX.
