Subreddit Gallery Viewer is a free browser tool that lets you view any subreddit as a stylish media gallery. Customize the grid with 2 to 7 columns and six thumbnail shapes, including masonry. Reposts merge into one card, deleted posts stay out of the way, and any picture opens full size or saves in a single click. Save the subreddits you come back to, and share a link that opens straight into one. No account, no install, nothing tracked.
