The short answer: yes, but know what you’re getting
Yes, there is a subreddit for finding subreddits. The most direct one is r/findareddit. You post what you’re looking for, and other users reply with relevant communities. It works, and it’s free.
But if you’re doing serious niche research — for marketing, content ideas, or business subreddits — that subreddit alone will waste your time. Here’s why: it mostly surfaces large, obvious communities that are already easy to find through Reddit’s search bar.
This guide covers the direct answer, then shows you how to use that subreddit properly, plus a few methods that find the smaller, active communities that actually matter.
The main subreddit for finding subreddits (and how to use it)
The subreddit you’re looking for is r/findareddit.
How it works:
1. Read their rules first. They have posting requirements.
2. Write a clear title: “Looking for a subreddit about X.”
3. Add details in the body: what kind of content, what level of activity, what tone.
4. Wait for replies. Users post suggestions, often with links.
You can also browse their “found” flair or search the subreddit itself. Someone else has probably asked about your niche already.
There are a few smaller alternatives:
– r/subreddit – less active, but occasionally useful.
– r/newreddits – for brand-new communities (risky, but early access can pay off).
– r/SubredditDrama – not for finding, but useful for understanding community culture and rules enforcement.
That’s the simple answer to “is there a subreddit for finding subreddits” — yes, r/findareddit is the main one.
Why big directories miss the best communities
Here’s the problem you’ll run into.
Ask r/findareddit for “marketing subreddits” and you’ll probably get r/marketing and r/socialmedia. Those are fine, but they’re huge. Your post will get buried in minutes. The actual valuable communities — the ones where a thoughtful comment gets real attention — are smaller.
These smaller communities rarely get mentioned in directory replies because people suggest what they remember, and people remember big names.
So use r/findareddit for a starting point, not the final answer.
A better method: the comment trail trick
Skip the directory entirely. This method finds niche subreddits that are actually active.
- Find one solid commenter in your niche. Someone who posts thoughtful, regular comments.
- Click their username.
- Open their comment history.
- Look at which subreddits they’re active in — not just one-off comments.
Someone who comments consistently in the same communities across weeks is showing you where the real discussions happen. That’s a much stronger signal than a random suggestion from a directory thread.
This works because comment karma is built through visible interaction history inside specific communities. Check the subreddit requirements for those communities first, so you know what’s expected before you participate.
How to verify a subreddit before you join
Once you find a candidate community, don’t join immediately. Run a quick subreddit quality check before you invest time there.
| What to check | Where to look | What’s a good sign |
|---|---|---|
| Active moderation | New posts, recent removals | Rules are enforced, not just listed |
| Real engagement | Comments on posts, not just upvotes | Posts have 5+ thoughtful comments |
| Post frequency | Sort by “new” | At least 3-5 posts per day (for most niches) |
| Rule strictness | Sidebar and wiki | Clear rules about self-promotion and links |
| Member behavior | Weekly threads, pinned posts | Long-time members help newcomers |
This matters because some subreddits look active but are actually dominated by low-effort content. Visible comment history and ongoing discussions matter more than subscriber count.
Common mistakes when looking for subreddits
- Joining too many at once. You can’t maintain a real presence in 15 communities. Pick 3-5 and go deep.
- Ignoring subreddit rules. Every community has its own requirements for posting and commenting. Check them before you do anything else.
- Judging by subscriber count. A 10,000-member subreddit with daily discussion beats a 1,000,000-member subreddit where posts die in minutes.
- Using only r/findareddit. The directory gives you a starting point, not a research strategy.
- Posting before lurking. Spend at least a few days reading the community before you contribute.
Quick checklist for your next search
- [ ] Ask r/findareddit for a starting point (or search their history first).
- [ ] Find 2-3 active commenters in your niche and check their histories for smaller subreddits.
- [ ] Check subreddit requirements and rules before participating.
- [ ] Run a quick subreddit quality check on each candidate.
- [ ] Focus on 3-5 niche subreddits, not 15.
- [ ] Lurk for a few days before your first comment.
Practical takeaway
Yes, there’s a subreddit for finding subreddits — r/findareddit. Use it to get started, but don’t stop there. The best communities for your niche are often found through comment histories and quality checks, not directory posts.
If you’re doing this for business purposes, remember that subreddit rules are strict, and visible comment karma matters more than any shortcut. Take the time to research properly, and you’ll find communities where your participation actually gets noticed.
For this use case, practical proxy option for Reddit workflows should be compared by pricing, setup difficulty, support quality, refund policy, and whether it fits your workflow.
FAQ
Q: What is the main subreddit for finding other subreddits?
A: The main one is r/findareddit. You post a description of what you’re looking for, and other users suggest relevant communities. It’s free and useful for getting a starting point, but it tends to surface larger, well-known subreddits rather than hidden gems.
Q: Is r/findareddit the only way to discover subreddits?
A: No. You can use Reddit’s search with specific keywords, check the comment histories of active users in your niche, and browse “related communities” links that many subreddits include in their sidebars. The comment trail method often finds better niche communities than any directory.
Q: How do I know if a subreddit is worth joining?
A: Check for recent posts (sort by “new”), read the rules in the sidebar, look at how many comments posts actually get, and observe how moderators handle rule-breaking. A small subreddit with real discussion is worth more than a large one where posts get no engagement.
Q: Can I use these methods to find business subreddits for marketing?
A: Yes, but be careful. Every subreddit has rules about self-promotion and links. Use the discovery methods to find communities, then read their rules carefully. Build a visible comment history first. Subreddit requirements often include minimum karma and account age, so check those before you try to post anything promotional.
Q: Are there any subreddits that list new or niche communities?
A: Yes, r/newreddits lists newly created subreddits, and r/subreddit is a smaller alternative to r/findareddit. These are less reliable for finding established communities, but they can be useful if you want early access to a niche before it grows.
