Written by the checker for a first version. Paste it into Vibecode as is, or change it to make the app yours.
Build an iPhone app for people who want to discuss shared interests in topic communities. The main screen should show a list of communities and a feed of posts with titles, community names, comment counts and vote scores. Tapping a community filters the feed. Tapping a post opens its full text and comments, with a field to add a reply. Add a compose button to write a text post and choose its community. Let me upvote or downvote posts and undo my vote. Use realistic sample communities, posts and conversations, and save my changes locally for now. Give it a clean, readable design with white backgrounds, dark text, orange accents and dark mode.
Opens Vibecode with this prompt ready. Your first build is free.
Reddit already has active communities, people who answer niche questions, and years of discussions that a homemade version would start without.

You can build a Reddit-style app where people browse communities, post, comment and vote. Start with sample discussions, then connect accounts and a shared database so people can join in.
Vibecode builds a first version from one prompt, and the checker would start with these parts: browse topic communities and their sample post feeds; open a post, read comments and add a sample post or reply; upvote or downvote posts, with votes saved on your device. Plan on a weekend for a working first version with its real features.
Vibecode's first build is free for new accounts that sign up with Google or Apple on the web or the iPhone app, as the account's first project: one build of about 10 minutes with up to 3 features, on sample data. After that you need credits, from a paid plan or auto-reload. For your own version of Reddit, the checker lists these costs: Vibecode Plus ($20 a month); Apple Developer Program ($99 a year).
Reddit already has active communities, people who answer niche questions, and years of discussions that a homemade version would start without. A version you build yourself won't have these: Reddit's established topic communities; existing posters and commenters; years of community discussions; experienced volunteer moderator networks.
