How to find the right subreddit
Treat every match as a candidate, not an approval
A useful subreddit matches the reader, the topic, and the post format. The Finder narrows the search, but the current community rules and Reddit's own composer make the final call.
- 01
Describe the real use case
Name the reader, the problem, and when they need the product instead of entering a broad category alone.
- 02
Compare topic fit
Open the candidate and check whether current discussions actually match the post you want to write.
- 03
Check rules and format
Read self-promotion, link, flair, title, recurring-thread, and account requirements separately.
- 04
Finish the check on Reddit
Use the native composer on posting day. A planned date or Finder result does not prove eligibility.

FAQ
Subreddit finder questions
How do I find subreddits for my niche?
Start with topic fit, then check whether the subreddit tolerates product links, beta asks, or founder feedback. A big subreddit is not useful if product posts are removed or treated as spam.
How does this subreddit finder work?
Enter your product or a keyword and review the candidate communities it returns. Treat every match as a lead, not an approval: open each community on Reddit, read its current rules, and check whether its posting options fit the action you want to take.
Where can I post my new project on Reddit?
There is no fixed list that works for every project. Use the finder to get topic candidates, then verify each community's current rules and recent discussions before preparing anything. A community that fits the topic can still disallow your link or launch post.
Can I post my product link on Reddit?
Sometimes, but the link usually needs context. Put the problem, what you built, and the feedback question before the link. Never lead with a hard sales CTA.
What makes a subreddit safer for self-promotion?
Safer communities have recent examples of product or website links, clear feedback angles, and a culture that accepts maker context. That still does not guarantee approval.
Is a big subreddit always better?
No. Smaller communities can be better if the audience is specific and the rules fit your post. Bigger communities often have stricter moderation and lower tolerance for launch posts.
Does WhereToPost auto-post to Reddit?
No. WhereToPost does not post, comment, vote, send DMs, or manage Reddit accounts. It gives a pre-posting fit and risk plan.
