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 · Only explicit rule shown is “No cross‑posting.” No stated flair/karma limits or dedicated promo threads.
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
Headline: short, explicit — e.g. “I built X — open‑sourced / deployed / need testers” or “How do I…?”; write in first person for project posts and detailed, technical voice for tutorials/discussions. Typical length: medium (200–800 words) with code links, architecture diagrams or demos. Tone: pragmatic, technical, no hype; what gets upvoted = working projects, demos, open source, thoughtful postmortems or deep technical threads; low‑effort promo or cross‑posts get ignored or removed.
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/web3dev'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.
