The best subreddits for SaaS founders are r/webdev, r/startups and r/SaaS. Where SaaS founders ask which tools to buy, swap honest feedback, and (carefully) share what they're building. Below: all 5, with each one's self-promotion policy so you don't get banned on day one.

The one rule that keeps you un-banned
Across every community here, the pattern is the same: be the most useful answer, not an ad.Lead with help, disclose when you mention your own product, and save launches for the designated promo threads. The fastest way to torch a new account is dropping your link in a top-level post. Reddit's spam filter and the mods both punish it.
