Find subreddits

How we search

  1. We turn your sentence into a few short searches, the words a redditor would use. You see them above the list.
  2. We run up to three of them in Reddit's own community search.
  3. We drop private, adult and quarantined communities, and any under 1,000 members.
  4. We rank up to 25 of the rest, the ones the most searches found and then the biggest, by how well their name and description fit what you wrote, with one line on why.
  5. If that line doesn't match what the community says about itself, we show the community's own description instead.

The ranking is a judgment from the community's own description, not a measure of how many of your buyers are there. Open a few and read the newest posts before you decide.

Promotion

Under each community you see what its rules say about promotion, if we have read them: allowed, allowed with limits, only in a set thread, banned, or not mentioned. Most large communities ban it outright. Where the rules don't mention it, moderators still remove posts that read like ads.

For the full list of a community's rules, use the subreddit rules checker.

Questions people ask

How do I find subreddits for my product?
Think about the people, not the product. A budgeting app for freelancers belongs where freelancers talk about money, not in a community about apps. Type a sentence about who uses it above and we search Reddit for the topics those people join, then rank what Reddit finds by fit.
How does Reddit's own subreddit search work?
Reddit matches your words against community names and descriptions. It works best with one or two plain words, like "freelance" or "personal finance". Long phrases often return nothing, which is why we turn your sentence into short searches first.
Where do the member counts come from?
From Reddit's search results at the moment we searched. The date under the list is when that was. Reddit doesn't say how many people are online in its search results, so we don't show a number for that.
What does "Not checked" mean?
We haven't read that community's rules yet, so we don't say anything about promotion there. Where we have read them, you see what they say and the day we read them. Rules change, so read them on Reddit before you post.
Why are some communities missing?
We leave out private communities, adult ones, quarantined ones and any with fewer than 1,000 members. We also only rank what Reddit's search returned for the searches shown, so a community whose name and description don't use those words won't appear.
Is what I type saved?
Your sentence and the list we found are kept so the link to them works and so the next person who types the same thing gets the same list. Don't type anything private.

Sources

The communities, member counts and descriptions come from Reddit's community search, read when you ask. What a community's rules say about promotion comes from rules we read earlier, with the date shown. The ranking and the line on each community are written by AI from those descriptions. Reddit changes them; tell us if something here is out of date.
