How are subreddits ranked?
First by self-promo friendliness (encouraged → case-by-case → 9-to-1 rule → banned), then by subscriber count within each tier. Friendlier-to-promo subs come first because they're easier wins.
What does the 9-to-1 rule mean?
Reddit's informal community guideline: out of every 10 things you post, only 1 should be self-promotional. The other 9 should be genuine value (comments, helpful answers, no links to your stuff).
How often is this list updated?
Quarterly. Self-promo policies and subreddit moderation change — we re-verify every 90 days.
Why isn't my subreddit listed?
We curate for English-language SaaS / B2B / indie-hacker buyer audiences. If you have a niche we should add, email hello@oneup.today.
Is this really free?
Yes. The first 3 unlocks of the full list are free; after that, sign up free with Google for unlimited filter runs and the full list every time.
