1. Get a public link
Testers need a link that opens in any browser. Most AI builders have a Publish or Deploy button that gives you one: Lovable and Bolt publish to their own addresses or a host such as Netlify, v0 deploys to Vercel, and Replit has Deploy.
If you build in Cursor, Claude Code or another editor, push your code to GitHub and connect it to a host such as Vercel, Netlify or Railway. Whatever you use, open the live link in a private window to make sure it works for someone who isn't you.
2. Ask for something specific
"Any feedback?" gets you "looks nice". A specific ask gets you real problems. Tell testers who the app is for and the one or two things you most want checked, for example: sign up on a phone, add your first expense, then find it again.
If sign-up is needed, add a demo login so testers don't get stuck, and list the problems you already know about so nobody reports them twice.
3. Post it and test others
Post your web app on VibeYoung with your link, your ask and the AI tools you used. Testers can filter by tool, so people who know Lovable or Cursor find your app.
While you wait, test a couple of other apps. It's the fastest way to get noticed, and helpful feedback earns credits towards free months.
4. Fix, then ship the next version
Mark the feedback that helped, fix what matters most, and post a new version with a short note on what changed. Testers who reported a bug are asked to confirm the fix, so you know it really works.
