Scrollify
For developers

Turn a Vercel preview URL into a scroll video, before it merges

Every push gets a fresh preview deployment. Paste that preview URL into Scrollify and get a scroll video or GIF for the PR description, the QA channel, or the stakeholder update — no screen recording, no waiting on a designer.

A preview link isn't a review

You open a PR, Vercel spins up a preview deployment, and you drop the link in Slack or the PR description. Half the team never clicks it — a raw URL doesn't say what changed, and clicking through on mobile to scroll a whole page just to sanity-check a layout tweak is friction most reviewers skip. A short scroll video of that exact preview shows the change in motion, right in the PR thread or the Slack message, without anyone leaving the app they're already in.

Just a link
  • ✕ Reviewers have to click through and scroll themselves
  • ✕ Non-technical stakeholders can't easily tell what changed
  • ✕ The preview expires or gets torn down before anyone circles back
A scroll video
  • ✓ Drop straight into the PR description or Slack — plays without a click
  • ✓ Anyone can see the whole page, top to bottom, in seconds
  • ✓ A permanent record of what the preview looked like, even after it's gone

Where this fits your workflow

  • PR reviews

    Embed a scroll video of the preview deployment in the PR description so reviewers see the visual change without pulling the branch.

  • QA sign-off

    Attach a capture to a ticket as proof the fix renders correctly, dated and reproducible before it ships to production.

  • Stakeholder updates

    Send a client or exec a video of the in-progress build instead of asking them to click a staging link on their phone.

  • Design QA

    Compare the shipped preview against the design file frame by frame using a clean, chrome-free capture.

How it works

  1. 1

    Copy the preview URL

    Every branch push gets its own preview deployment URL — grab it from the PR checks or your dashboard.

  2. 2

    Paste it into Scrollify

    Pick a format — MP4 for Slack and Loom-style threads, GIF for inline PR comments — and capture.

  3. 3

    Share the link or file

    Drop the download or share link into the PR, the ticket, or the channel — done before the preview environment spins down.

Note: password-protected preview deployments (Vercel's team-only previews) aren't reachable — make the preview link public, or capture from a already-shared preview URL.

FAQ

Does this work with password-protected previews?
No — Scrollify captures public URLs only. Vercel's Deployment Protection (password or SSO) blocks automated capture the same way it blocks any bot. Disable protection temporarily, or share a public branch preview instead.
What if the preview deployment gets torn down later?
Your Scrollify export is a separate saved file — it keeps working as a record of what the preview looked like even after the deployment itself is gone.
Can I automate this for every PR?
Scrollify's REST API and scheduled captures can be scripted into a CI step that captures the preview URL Vercel posts on each PR — see the API docs to wire it up.
Does this only work with Vercel?
No — any public preview URL works, including Netlify, Render, Railway, or a staging subdomain. Vercel just makes a fresh public URL per push, which is what makes this workflow so common there.
