Subreddit rules check
r/ruby
Can you promote here?
The rules clearly permit sharing your own product or project. Follow the format norms below, disclose that it is yours, and lead with substance: allowed is not the same as welcomed for low-effort pitches.
Links
The rules clearly allow links. A plain-text mention still often outperforms a URL from a young account.
What this community rewards
Dominant post formats: showcase, news, discussion
Use a clear, descriptive headline (ProjectName — what/why/what changed). Write in first person when announcing your project/role, keep body short-to-medium (1–3 paragraphs) with a concise summary, links to repo/changelog, and concrete technical details or benchmarks. Tone: professional, helpful, non-clickbait. Upvoted: useful releases, deep posts, migration/case studies; removed: off-topic posts or obvious spam.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked July 2026. Rules change and moderators have the final say: verify at r/ruby's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
