r/vibecoding: rules, karma requirements and posting culture
A fast-growing show and tell board for things built with AI coding tools. Launch posts are the norm here, but most new posts get held before anyone sees them.

The short answer
r/vibecoding publishes no karma or account age requirement, and no rules were available when we looked. The filtering is heavy all the same: about 60% of new posts in our sample were held by AutoModerator and another 17% or so were removed by Reddit's filters, leaving roughly one in five visible. Every post that stayed up had a flair, and two thirds were Showcase/Project. Showing what you built is the point of the place, so the hurdle is getting through the filter, not the topic.
Who posts here
People who say they are not developers post browser games and small apps next to working engineers who talk about context tokens, MCP tools and multi-agent setups. Nothing is explained, but nothing is gatekept either: a beginner asking how to get better UI out of a model gets practical tips. The pushback is about quality and honesty, not about your skill level.
- Hobbyists and first-time builders shipping a game or small app made with an AI coding agent.
- Solo founders sharing early revenue, a launch or a request for feedback.
- Working developers building tooling around coding agents, often open source.
- Heavy users comparing models, subscription plans and usage limits.
- Sceptics and experienced engineers in the comments who call out slop and overclaiming.

Reddit counts a removal by the subreddit's own AutoModerator rules as a moderator removal, so that share is not all human. Held by AutoModerator means the post is waiting in the mod queue.

The culture
r/vibecoding is a year and a half old and has about 370,000 members, up from roughly 126,000 in 2025. It gets close to 200 post attempts a day. The feed is a demo reel: a screen recording of a browser game, a desktop widget, a dashboard built for a relative, an open source tool for stretching an agent's usage limits. Posts run long for Reddit, a median of about 135 words, because people explain what they built and how.
Around the showcases sit a few other kinds of post. Memes about burning through a plan or waiting on an agent. Questions about which subscription to buy or how to stop a model making bad design choices. Opinion pieces about whether security and maintainability still matter, which draw the experienced engineers out to disagree. There is also a weekly build challenge run as a discussion thread.
The fault line is slop. The word is used freely, sometimes by posters about their own work, and one builder rebuilt a portfolio after the comments called the first version exactly that. The room is friendly to people who built something and say plainly how. It turns on posts that oversell, and a commenter will say so in the first reply.
What lands
- Our sample caught posts when they were new, so we cannot rank by votes. These are the kinds of post that stayed up and drew replies.
- A short video of the thing working, with what it is, which tools built it and how long it took.
- A build story with a reason behind it, such as making something for a family member or to fix your own bad habit.
- Honest small numbers. Posts about a first trickle of revenue after a year read as credible because the amount is modest.
- A specific workflow question, like how to get consistent UI from an agent, which gets concrete tool and prompt suggestions.
What gets removed or ignored
- Most posts never appear. About 60% were held by AutoModerator and about 17% removed by Reddit's filters. Our data does not show what triggered either.
- Moderator removals after the fact are rare, well under 1% of the sample, and the one we saw was a help question with its content gone.
- No rules were retrievable, so we cannot list banned topics. Treat any claim about a specific threshold as a guess.
The unwritten rules
- Say which model and tools you used. It is the first thing people ask, and posts that stayed up usually lead with it.
- Links in the post and the comments are normal here. About 11% of comments carry one, far more than most subreddits.
- Ask for feedback and mean it. Showcase posts that end with a real question get replies. A bare link with a one-line title mostly does not.
- Do not oversell. Grand claims and paid offers dressed as favours get called snake oil in the comments.
- Comments are short, around 15 words, and often just a screenshot of someone's own project or a quick tip.
Self-promotion
We found no written rule on self-promotion, and the subreddit is built around it: two thirds of visible posts are Showcase/Project, most with a link to the thing. Open source repos, free tools and playable games are the easy cases. Paid products and community invites also stay up. The limits are practical. Most posts are held by a filter before anyone sees them, so a new account with a launch post is the likeliest to vanish, and the audience is quick to mock anything that reads as an ad written by a model. Builders also mention their own tools in comments when answering a question, usually alongside a second option.

Common questions
How much karma do you need to post in r/vibecoding?
No number is published. In our sample about 60% of new posts were held by AutoModerator and about 17% were removed by Reddit's filters, so only around one in five stayed visible. That points to an account threshold of some kind, but the moderators do not state what it is.
Can I promote my app or project in r/vibecoding?
Yes. Showing what you built is the main activity, and about 67% of visible posts use the Showcase/Project flair. Say what it does, which AI tools you used and what feedback you want. The risk is the filter, not the topic.
Why is my r/vibecoding post not showing up?
It was most likely held by AutoModerator or caught by Reddit's spam filter. Together those took out more than three quarters of the posts we sampled. Check the post while logged out. If it is held, a moderator has to approve it.
What kind of posts work in r/vibecoding?
Project showcases with a demo. About 43% of posts that stayed up are videos, text posts are about 30%, and the typical post is around 135 words. Games, small apps and tools for coding agents are the most common subjects.
Data as of October 4, 2026. Numbers come from public Reddit data (the Arctic Shift archive and GummySearch) sampled on this date. Removal share counts posts taken down by moderators, AutoModerator or Reddit's own filters. Banner and icon belong to the community. Moderators change rules without notice, so treat the sidebar as the final word.
