Question 1

How does the subreddit finder work?

Accepted Answer

You describe your product, and we match it against a hand-researched library of subreddits using AI embeddings. We then rank the communities that allow promotion by how well they fit your idea, and flag the relevant ones where self-promotion is removed. Every result links to that subreddit's official rules.

Question 2

Where does the data come from? Is it accurate?

Accepted Answer

Each subreddit profile is researched from its public rules and multiple independent community guides, and links directly to the subreddit's rules page so you can verify everything yourself. Reddit rules change often and moderators have the final say — always read the current rules before posting.

Question 3

Why are some subreddits marked 'avoid'?

Accepted Answer

Many large or on-topic subreddits remove or ban self-promotion entirely — for example r/marketing or r/InternetIsBeautiful. We surface the relevant ones so you don't waste effort or risk a ban posting where promotion isn't allowed.

Question 4

Will I get banned for promoting on Reddit?

Accepted Answer

You can, if you ignore a community's rules or only ever drop your own links. Redditors expect you to contribute value first and self-promote sparingly. Follow each subreddit's self-promotion policy (linked in every result) and you'll be fine.

Question 5

Is this really free?

Accepted Answer

Yes, the subreddit finder is completely free. It's built by RedReplier, which also offers paid Reddit, X, Bluesky and Hacker News lead monitoring if you want to track mentions of your product over time.

Question 6

How many subreddits do you cover?

Accepted Answer

We cover a curated set focused on startups, SaaS, apps, indie makers, developers and marketing — the communities most relevant to launching a product. We keep adding more over time.
