Subreddit rules check
r/java
Can you promote here?
Promotion is allowed only with moderator permission (or inside designated threads). A short, honest modmail before posting costs two minutes and functions as a safe-conduct pass; skipping it is the most common avoidable removal.
From the rules · Posters who share their own projects commonly include an explicit disclosure in the post text.
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: news, showcase, discussion
Use short, technical headlines (e.g., "JDK 27: General Availability") and a concise body with concrete details, links, and optionally first-person when announcing your project. Typical posts are medium-length, factual, and professional; include benchmarks, changelogs, or repos. Upvoted: clear releases, technical deep dives, useful tooling. Avoid marketing fluff — if you’re posting your own product, ask the mods or include an explicit disclosure.
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 October 2026. Rules change and moderators have the final say: verify at r/java'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.
