Launch Posts
You know where to post and how to tag each link. The part that actually stops people is describing your own app without sounding like a press release — five times over, for five venues that punish the same wording differently.
Why one post is not five posts
The same paragraph is a fine tweet, an ad on Reddit, a rejected Show HN and a wasted maker comment. X wants one line. Reddit wants a person, plainly saying what the thing is and what it costs. A Show HN title literally has to start with “Show HN:”, and Hacker News moderates against titles written to stand out. Product Hunt wants the origin story the listing has no room for.
Pick your app above. Your listing and a few rough notes about why you built it are the only things any of these drafts are allowed to state as fact.
