# Share a v0 Design for Feedback — Comments on the Page, Not in Slack

> v0 turns a prompt into a working UI in minutes; getting useful feedback on it takes longer. How to hand a v0 page to reviewers as a fixed version they can comment on, line by line, without a Vercel account.

# Share what v0 built

v0 is fast at the part that used to need a designer and a sprint: _"a
pricing page with three tiers and a comparison table"_, _"an onboarding
screen for the mobile app"_, _"a dashboard for these metrics"_. In ten
minutes it looks real. Then it needs to go past a founder, a PM or a
client, and the review is where the time goes.

## Why the feedback comes back vague

**The chat link** shows the latest state of a conversation, not the version
you meant. If you keep prompting after sending it, the reviewer comments on
something that no longer exists.

**The deployment URL** is a real site, which is the point, and it has no
place for the reader to write. So you get _"the second card feels off"_ in
a DM, and a round of _"which second card?"_

**A screenshot** loses hover states, the mobile layout and everything below
the fold, and nobody can quote the copy back to you.

What you want is the page, frozen at the version you chose, with a comment
thread attached to each thing someone points at.

## One screen or a landing page

1. In v0, ask: _"Rewrite this as one self-contained HTML file. Use the
   Tailwind CDN build, inline all JavaScript, and replace imported
   components with plain markup."_
2. Copy the file. Check it renders in the free
   [HTML viewer](/tools/html-viewer) if you want to be sure.
3. Paste it into [Comma](https://commareports.com/new) and send the link.

Reviewers select the headline, the tier name or the CTA and leave a
comment pinned to it — [commenting on HTML](/comment-on-html). No Vercel
account, no v0 account, no Comma account.

The page runs in a sandbox with scripts on, so toggles, tabs and
carousels still work. Libraries load from jsDelivr, unpkg, cdnjs and
esm.sh. What will not work is anything that called your API — the static
copy has no backend, which for a design review is usually what you want.

## A multi-page app

When the thing under review is the flow, not one screen, use a
**Website** instead of a report. Build the project (`npm run build`), zip
the output folder (`dist/`, `out/` or `build/`), and upload it on the
Websites tab. Comma hosts it on an isolated deployment and puts the same
anchored comment layer over the live pages.

Two limits worth knowing while the feature is new: the upload carries text
files only, so reference images by absolute URL rather than bundling them,
and anything that needs a server at runtime (API routes, server actions)
needs to be deployed somewhere that runs a server.

The comments are also readable by an agent. The MCP tool
`list_website_comments` returns each comment with the page path and the
element it was left on, so a coding agent can work through the review and
mark each one resolved as it fixes it.

## Who can see it

A report can be a public link, password-protected, invite-only, or
limited to your team or email domain — [sharing options](/docs/sharing).
A Website starts private; invite reviewers as commenters or make it
public with comments on. Either way a client can review a prototype
without it being indexed or forwarded around.

## The second round

Take the comments back to v0, get the revision, and update the **same**
report. The link you already sent now shows the new version, the previous
one stays in the revision history, and open threads carry over so the
person who raised a point can check it and resolve it.
