Self promotion subreddits: where Reddit actually lets you promote

These 13 subreddits allow self-promotion, whether any time, once, or in a set weekly or monthly thread. We read each one's rules, description and posting guidelines on Reddit on 13 November 2026, and the rule on each card is quoted from the subreddit itself. Most of them suit indie makers and early founders looking for feedback, testers and first users. Funded brands get more out of the big communities' weekly threads and out of answering questions.

How to post in these subreddits

Read the full rules and the pinned posts first. Rules change, and some only live in the sidebar or wiki.
Lead with what you learned or what you need feedback on. The link comes after.
Say plainly that you made it.
Reply to every comment for the first day. A post you abandon reads as an ad.
Don't post the same text in five subreddits on the same day. Write each one for its community.
Check your draft against the subreddit's rules before you post it.
