Subreddit rules check
r/opengl
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, discussion, question
Write in first person, headline = descriptive project + tech (e.g., “Volumetric Render Engine (OpenGL & C++)”). Typical posts are medium-to-long (screenshots/links + explanation), conversational and technical. Open with a short story or a clear question, include repo/demo links and specific details. Upvotes reward project showcases, optimization writeups, tutorials and honest postmortems; avoid low-effort “look at my thing” posts without context or questions.
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 September 2026. Rules change and moderators have the final say: verify at r/opengl'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.
