Subreddit rules check

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.
From the rules · Apply the Promotional flair for project posts, follow Reddit's <10% self-promo guidance, and engage in the comments (no drive-by/karma-farming).
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: discussion, showcase, news
Headline: clear, factual, non-sensational (match linked title if linking). First or first-person is fine for project posts; focus on what your open-source project does, contribution opportunities, license, and notable tech choices. Typical length: short title + concise body (3–6 paragraphs) with a link to repo/docs and examples. Tone: helpful, technical, community-oriented. What gets upvoted: useful projects, meaningful discussions, news. What gets removed/downvoted: drive-by self-promo, low-effort posts, memes, sensational titles.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.

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.
