Why the ban risk is high

  • Enforces a ~90/10 rule — 9 value posts for every 1 that promotes.
  • Actively moderated; off-guideline posts are removed fast.
  • Explicit limits on self-promotion and marketing language.
  • Rewards transparency; disclose that it's your project.

The rules, in plain English

Self-promotion is restricted and must follow the 90/10 rule; standalone promo and paid-product posts are frequently removed. Share open-source, technically substantive content and disclose that it's yours.

How to post here safely

Do
  • Frame the post as a lesson, guide, or question — value first.
  • Read the subreddit rules and respect any self-promo ratio or thread.
  • Engage in the comments; mention your tool only as context.
Don't
  • Don't put a link in the title.
  • Don't drop a bare product pitch outside the designated thread.
