How to add user feedback to a v0 app (with a prompt you can paste)

Paste one prompt into v0 to add a Feedback button to the app it built, so your first users can report problems and ideas while you iterate.

Short answer: v0 builds Next.js apps, so ask it to add Bopmigo to app/layout.tsx with next/script. Deploy to Vercel, and a Feedback button appears on every page.

A pricing page with the Bopmigo Feedback window open on Request
The Feedback window on a live page. People pick Problem, Request or Idea and write a line.

The follow-up is answered on the page where it happened.

Add it to your v0 app

  1. 1

    Create your Bopmigo project

    Sign up at bopmigo.com, choose Website, and add your v0 address (for example yourapp.vercel.app). Copy your line from Install snippet:

    HTML
    <script src="https://bopmigo.com/widget.js"
  data-project="YOUR-PROJECT-ID" defer></script>
  2. 2

    Paste the prompt

    Paste the prompt into v0 with your own project ID.

    Prompt
    In app/layout.tsx, load this script on every page using next/script with strategy="afterInteractive", inside <body> after {children}. Keep everything else as it is.

src: https://bopmigo.com/widget.js
data-project: YOUR-PROJECT-ID
  3. 3

    Check the change

    Check that it used the Script component from next/script in the root layout.

  4. 4

    Publish

    Deploy and open your Vercel address.

  5. 5

    Send yourself a test

    Open the live page, choose Feedback and send a short report. It arrives in your Bopmigo inbox (and by email, if you turned that on). Reply, then open Feedback again to see your answer.

v0 tips

  • Add your production domain and your preview addresses (.vercel.app) to the project in Bopmigo.
  • Use next/script, not a plain <script> inside a component, so it loads once across page changes.
  • The full Next.js steps, including the Pages Router, are in the Next.js guide.

Why an app built with AI needs this early

AI builders get you to a working app in hours, which also means nobody has clicked through every path yet. Your first users will. A Feedback button means you hear about the broken button or the confusing step while they’re looking at it, with the page it happened on, instead of from a one-star review or silence.

More on this: feedback from your first users and how I’d set up a SaaS in 2026.

What v0 users tend to report

  • Components that look finished but have no behaviour behind them yet.
  • Layouts that break between tablet and phone widths.
  • Copy that confuses people because it was a placeholder.

Your first week

  1. 1

    Day 1: send three test reports yourself

    One problem, one request, one idea, from a phone and a laptop. Check each arrives with the page and a screenshot.

  2. 2

    Days 2 to 5: invite your first users

    Tell them about the Feedback button in your welcome message. Early users are happy to help if it takes a sentence.

  3. 3

    Days 6 and 7: fix and reply

    Fix the most repeated problem, reply to everyone who reported it, and ask them to try again.

Questions

What if v0 made a Vite app instead?

Then the line goes in index.html before </body>, like the React guide.

Will it slow down my app?

It loads after the page is interactive, so it doesn’t hold up your first render.

Why doesn’t the button show?

Check that the address you’re on is listed in your Bopmigo project, that the change is live, and open a private window in case of caching. If your site has a Content Security Policy, allow https://bopmigo.com.
