Can someone comment on my v0 app without a Vercel account?

Yes — if you deploy the app to a public URL. The deployed app opens in any browser with no account. If you share the v0 chat link directly, reviewers need a v0 account to do anything beyond read. Deploy first, then share the live URL (or put it in a review tool that supports guest commenting, like Drafty or Markup.io).

What's the difference between sharing the v0 chat link and sharing the deployed app?

The v0 chat link shows your prompt history — the conversation you had with v0 to build the app. The deployed app URL opens the actual working application. For feedback, you almost always want the latter: testers interact with the real app, not your build process.

How do I get specific feedback on a v0 app instead of vague responses?

Two things help: first, share the deployed URL rather than asking testers to describe what they see in a screenshot. Second, use a review tool that lets them pin a note to the exact element — "this button" is unambiguous when it's literally pinned to the button. Open questions like "what do you think?" produce vague answers; element-anchored comments produce specific ones.

How do I collect v0 feedback from multiple testers without losing track?

Send everyone the same review link from a tool like Drafty or Markup.io rather than collecting feedback in separate Slack threads or email replies. All comments land in one place, anchored to the same version of the app. You're not reconciling four different sets of annotated screenshots or chasing responses across three channels.

Do I need to deploy my v0 app before getting feedback?

For any meaningful review, yes. v0's Preview mode lets you see the app yourself, but sending a preview link to someone else lands them in your v0 chat — not the running app. Click Publish in v0 or push to a Vercel project to get a URL you can share. The deploy takes under a minute.

What's the best way to get feedback on a v0 app on mobile?

Share the deployed URL and open it on their phone — v0 apps are React-based and responsive by default. If you're using a review tool, check that it supports mobile commenting (Drafty does; some tools are desktop-only). For a screen share, mirror your phone to your Mac (QuickTime + USB or AirPlay) so testers see the actual mobile experience, not a browser resize.

How to get feedback on a v0 app

Quick answer

To get feedback on a v0 app, deploy it to a public URL first — then share that link, not the v0 chat. v0's built-in sharing shows reviewers your prompt history, not the live app. Once deployed, the clearest feedback comes from a tool that lets testers pin notes to the exact screen element they mean, so you're not decoding "the button near the top" from a Slack message.

Step 1

Deploy it first, then share the live URL — not the v0 chat link

v0 has a Share button in the chat interface. Most builders reach for it and send the link — but what reviewers get is the full prompt-and-response history, not a live version of the app to interact with. The right path: click Publish in v0 (or push to Vercel) to deploy your app to a real URL, then share that URL. A deployed v0 app opens in any browser without a Vercel account — your testers can tap through it on their phone the same way a real user would. This is the most common thing builders get wrong: the share link and the app link are two different things in v0.

Step 2

Drop the URL into a review tool so testers can pin notes to the exact element

Once you have a live URL, paste it into a review tool — Drafty, Markup.io, or Ruttl all support live URLs. You get a shareable review link your testers open in their browser. They hover the element they're talking about, click, and leave a note pinned right to it. No account, no install. The difference from "here's my app, what do you think?": every comment arrives attached to the exact button or screen section the tester meant. "The CTA on the pricing tab feels buried" pinned to that exact element is actionable. "The pricing thing looks a bit off" in a Slack DM is not. Works on mobile too — testers can open the review link on their phone and tap the element directly.

Step 3

Walk through it live on a screen share for flow feedback

A 30-minute screen share beats a week of async Slack for flow issues. Open your deployed v0 app on a screen share (Zoom or Google Meet) and click through each screen with the tester watching. The discipline that makes it useful: don't explain what you built before they react. Ask "what would you tap first on this screen?" before you point at the primary action. Take notes in a doc as they talk — don't try to argue or clarify in the moment. Send back a list of timestamped action items after the call. Screen shares are especially useful for interaction bugs and multi-step flows that are hard to annotate on a static review link.

Step 4

Send screen-specific questions, not open-ended "what do you think?"

Open questions produce useless answers. Structure your feedback request by screen: onboarding, dashboard, settings. For each screen, ask one concrete question: "After you land on this screen, is it clear what you're supposed to do next?" A short form with a screenshot of each screen as a header image works for testers who won't open a tool. Limit to six questions — anything longer kills completion. Route answers into a sheet and bring the raw responses to a follow-up call. One thing v0 builders often get wrong: they ask for visual polish feedback before testers have formed a view on whether the flow makes sense. Get clarity and flow feedback in round one; request refinement in round two.

The faster way

If testers keep saying "the button near the top" or "the thing on the second tab" — paste your deployed v0 URL into Drafty and send the review link. They open it on their phone or laptop, tap the exact element they mean, and leave a note pinned right there. No account. You see every comment in one place and resolve them when they're fixed. Works on any public v0 deployment, Vercel preview URL, or staging link.
