It reads the target subreddit's own public title and description, pulls out the most distinctive words, and searches Reddit's public community index with them. Results are ranked by how closely they match those words and by subscriber count, then filtered for NSFW, private, quarantined, and near-empty communities.

How do I find subreddits similar to a given one?
To find similar subreddits, enter a subreddit name into this tool: it reads that subreddit's own public title and description, searches Reddit's community index with the resulting keywords, and returns a ranked list filtered for NSFW, private, quarantined, and near-empty results. No login, no API key, and no personal data are required.
Find similar subreddits
Reads public data only. No login or API key needed.
This tool reads the Reddit public subreddit and search APIs with no authentication. Similarity is derived from keyword overlap with the target subreddit's own public title and description, not from a human-curated list. Results and subscriber counts reflect the state at the time of the search and can change at any time after.
Why finding related subreddits matters.
Most subreddits are not the only place a given audience gathers. A brand, researcher, or moderator that only watches one community misses the adjacent ones where the same people are already talking, often in smaller, more focused spaces with less competition for attention.
Manually browsing Reddit's own suggested-communities widget only surfaces a handful of options and leans on Reddit's internal ranking, which is not tuned for research or outreach use cases. This finder runs the same kind of lookup on demand, against the words the target subreddit actually uses to describe itself.
Every result is filtered for NSFW content, private and quarantined subreddits, and communities with too few subscribers to be a meaningful match, so the list stays usable without a manual pass.
How the search works.
Step 1
Enter a subreddit
Type or paste any subreddit name. The tool strips a leading r/ or /r/ prefix automatically, so either format works.
Step 2
Keywords, then a search
The finder reads the target subreddit's own public title and description, extracts its distinctive keywords, then runs a community search with them.
Step 3
Ranked, filtered results
Matches are ranked by keyword relevance and subscriber count, with NSFW, private, quarantined, and near-empty subreddits filtered out first.
The community search this finder runs maps to one of the 54 REST endpoints documented per the Redditapis OpenAPI spec at docs.redditapis.com/openapi.json, so you can run the same lookup for hundreds of subreddits at once, or build it into a research pipeline, with a Redditapis key.
FAQ.
No. Every result comes from a live keyword search against Reddit's own community index at the moment you run it, not from a maintained list. That means results can shift as new subreddits are created or existing ones grow.
A narrow or unusual topic may have no other public, safe-for-work community that shares its keywords. This tool reports that honestly rather than padding the list with loosely related subreddits just to fill space.
No. NSFW-flagged, private, quarantined, and near-empty subreddits are filtered out of every result set, so the list stays safe to share and free of dead communities.
No. The finder reads public subreddit and search data that any visitor can access without logging in. No Reddit account, no API key, and no personal data are required to run a search.
