SubRedds

SubRedds is a map of Reddit. It keeps track of more than 100.000 subreddits, SFW and NSFW, and shows for each one how many members it has, how many posts a day it gets, how old it is and when it was last checked. The list can be searched, filtered by size, activity and content rating, and sorted by any column, so finding the biggest, busiest or newest communities on any topic takes seconds.

Every subreddit opens as a gallery of all its pictures and videos, newest first, loading as you scroll, all the way back through the public Reddit archives. Any Reddit profile can be browsed the same way, across every subreddit the person has posted in. Switches for pictures, videos, media posts only, duplicates and deleted posts, and a layout of one to eight columns with your choice of thumbnail ratio, make the gallery yours.

Browsing needs no account. A free account adds a sidebar of saved subreddits and users, sorted into sections you name, and a heart that keeps any post.
