Start. Pick a track above — the users you understand best.
Imagine. Finish the sentence: “I wish it could…”
Build. Paste the starter prompt into Lovable, Base44, Replit, or Claude Code, then bend it toward your own idea.
Submit. Join, then post a Launch — a link others can test, plus a short walkthrough.
Explore. Try what everyone else shipped this week.
Vote. Like your favourites on the board — likes are the votes.
Need to know how to code? No — the tools do the coding, you bring the idea and the taste.
Can I use any tool? Yes — the four above are just suggestions.
Need the original app installed? No — you're building a companion, not a plugin.
What counts as shipped? A link someone can open and test, plus a short walkthrough. Rough edges are fine.
