Free Reddit subreddit finder

Search for public subreddits that match a product, a problem, or an audience. Use the list to decide what a project should watch. A community in the results is not a recommendation to promote there.

Find subreddits
Search public communities by topic. This returns at most 8 names. It does not open a page on this site for each one.

Logged-out searches share a limit of 3 per day with the mention tracker, and 100 across everyone.

How to use a result

  1. Open the community on Reddit and read the new posts, not the top posts from last year.
  2. Count how often someone asks what to use. If that question is rare, skip the community.
  3. Read the promotion rules. A monitor that only produces removals is not worth the slot.
  4. Save the keepers on a project. The short list guide is the longer version of this step.

FAQ

Does this create a page for every subreddit?
No. Search results stay on this page. Each name links to Reddit. CollectIntent does not publish a directory of communities.
How many searches can I run?
Without an account, this search shares a limit of 3 calls per day with the other free Reddit searches, and 100 calls per day across every visitor. A project is how you keep a list and watch it.
Should I add every result?
No. Open the community, read a week of posts, and check whether people ask what to use. Add it to a project only if you would answer those threads.
Does a result mean the subreddit allows promotion?
No. The finder returns a public name and description. Rules about promotion are on the community itself. Read them before you post.
