How to post your app on Reddit without getting removed
Posts about your own app get removed on Reddit for three reasons: a link in the body, a title that reads like an advert, and a post that ignores the subreddit's self-promotion rule. The fix is the same every time: write as the person who built it, put the link in the first comment, pick the right subreddit, and read its rules before you post. Demopost drafts the post, the first comment, a flair and a rules checklist from a paragraph you write.
Pick the subreddit first
There are two kinds that work. Topical communities, where your users already are, want the topic first and the app second. Maker communities such as r/SideProject accept "I built this" posts outright. Ask Demopost for suggestions and it names six with a one-line note on each one's self-promotion stance; it is honest when a community is strict. Start with one of each kind.
Write the context in your own words
The draft grows from a paragraph you type: why you built it, what it does, what you want to ask the community. This is the part that cannot be faked. Readers reward a real reason and a real question, and downvote a pitch. The writer keeps your facts exactly, adds no personal details you did not state, and will reject its own draft if it slips in a number your paragraph does not contain.
What the draft gives you
- A title someone would click for its own sake, under 200 characters, no emojis, no exclamation marks.
- A body of 120 to 300 words: what it does, why you built it, one limitation, and a question at the end. No links, no hashtags.
- A first comment of one to three sentences with the link. That is where the link lives.
- A likely flair, and a checklist of three to five rules to confirm on the subreddit's page.
Post it, then stay
- Open the subreddit's rules once. Check the self-promotion limit, whether links are allowed, whether there is a weekly promo thread you should use instead.
- Open the submit page, choose Text, paste the title and body, set the flair, post.
- Add the first comment with the link immediately.
- Reply to every comment for two hours. A thread with the maker in it survives; a thread without one sinks.
- Paste the post URL back into Demopost and mark it posted.
If it still gets removed
Read the removal reason; moderators usually name the rule. Most often it is the self-promotion ratio, which means you need a history of ordinary comments in that community before a post about your own work. Spend a week being useful there, then try again. Do not repost the same text in a second subreddit on the same day; cross-posting is the other reliable way to get flagged.
