Subreddit finder

How this subreddit finder works

A subreddit finder answers a simple question: given a niche, which public Reddit communities actually talk about it. Type a topic such as skincare, SaaS, or pickup trucks. We search Reddit’s community index and return a short list with member counts, public descriptions, and links so you can open the real subreddit before you post.

How the ranking is calculated

1. 1

   Search by relevance

   Reddit’s subreddit search runs against your query, sorted by relevance, up to 25 matches. Multi-word queries stay as you typed them.

2. 2

   Drop rooms you cannot use

   Private, banned, gold-restricted, and quarantined communities are removed. So are subreddits with fewer than 50 members — too small to be a reliable channel.

3. 3

   Sort by members

   The remaining public subreddits are ordered by subscriber count, largest first. We keep at most 15. NSFW is labeled when Reddit marks the community that way.

Member count is not quality. A 2-million-member generalist subreddit often ranks above a 20k specialist room that would convert better. Read the blurb, open the subreddit, and check the last week of posts before you write anything.

Who this is for

• Marketers picking subreddits for a Reddit campaign, not guessing from memory.
• Founders checking where a product category already has an audience.
• Researchers mapping a niche before they lurk or ask a question.

Limits

One free scan per visitor, shared across all free tools. Results are public communities only. Reddit search is imperfect — a misspelled niche or a brand-new subreddit can return nothing useful. Try the common name people type, then a broader category. To watch mentions of a product instead, use the mention finder.
