Bavior puts two subreddits side by side: size, activity, self-promo rules, and who each one is for. One table, and you know where to post. Included with your account.
A subreddit comparison puts two communities side by side. It shows members, activity, the self-promo rule, and who posts there. It does not return a user-overlap percentage. Nobody can compute that from public Reddit data. What you get instead is the audience-fit row, which says whether two subs draw the same kind of person. That row, plus a promo rule you can live with, decides more than size does.
The same five signals for both, so the difference shows at a glance.
| r/SaaS | r/startups | |
|---|---|---|
| Members | 210K | 1.9M |
| Posts/day | ~30 | ~80 |
| Self-promo rule | Allowed Saturdays | Weekly thread only |
| Best for | SaaS builders, pricing & growth talk | Founders at any stage, fundraising & hiring |
| Karma needed | None enforced | ~10 comment karma |
The bigger number does not win. Weigh these four things first.
A sub with millions of members but twenty posts a day buries you fast. A smaller, busier community often puts your post in front of more of the right people.
A rule that names a weekly thread or a format is one you can follow. "No spam" with no detail usually means a filter that removes your post quietly.
Two subs on the same broad subject can serve very different people. Read the "best for" row, not just the name.
The bigger sub is useless if you cannot clear its karma or age bar yet. Compare where you can post now, not where you would prefer to.
If the two look close on paper, let the karma gate decide. Post where you clear the bar today, and build toward the stricter one for next time.
r/name vs r/name. The two you are deciding between.
Size, activity, and the self-promo rule, read from each community.
Five signals, lined up, so the difference is obvious.
Member count is the number Reddit shows first. That makes it the easiest one to compare and the easiest one to overrate. These four signals do far more to predict whether a post gets seen and survives.
Member count. How big the audience is, so you can weigh reach.
Posts per day. A live community versus a quiet one.
The self-promo rule for each. Where a link is safe, and where it is not.
Who the community is for, in one line.
Comparing tells you where to focus, not where to post forever. Bavior works whichever community wins, end to end. It reads the rules, finds the buying-intent threads, and drafts native replies. Nothing goes out until you approve it.
It compares public numbers, not the mod team behind them. Two subs can look alike on paper and behave very differently once you are the one posting. Give the winner one test post before you build a plan on it.
Set a goal and Bavior runs the loop end-to-end — find, draft, post, verify, replan. You approve.

Not as a percentage. Nobody can compute a user-overlap number from public Reddit data. The comparison returns five signals per subreddit — members, posts per day, self-promo rule, who the audience is, and karma needed — and the audience-fit row is what tells you whether two communities draw the same people.
Compare the finalists on activity and audience fit, not member count. A smaller subreddit full of your exact buyer usually beats a huge general one. A promo rule you can clear matters more than a bigger number.
