Preview your site in the tool that matches the change: use the page preview in a website builder or CMS for draft content, and a local, branch, or pull-request preview for code changes. Then confirm the preview shows the intended version, inspect it at desktop and mobile sizes, test visitor-facing interactions, and check who can open its URL before sharing it. A preview is a review step—not proof that the live site will behave identically in every environment.
Choose a preview that matches what changed
Start by identifying whether the change is unpublished page content, a CMS entry, or code and design work. The preview needs to include the thing you changed. A page-builder preview may show a saved draft, while a code deployment preview may show a branch but still use production CMS data unless it is configured to retrieve drafts.

| What you are reviewing | Preview to use | What to verify |
|---|---|---|
| Copy or layout edited in a hosted site builder | The builder’s page preview | Correct page and draft; desktop and mobile appearance; whether editing controls obscure the visitor view. |
| Unpublished CMS content | The CMS draft or staging preview | The preview renders the draft and the content has not unintentionally gone live. |
| Code on your own machine | A local development server | The site runs with the expected development data and the changed page is rendered. |
| A proposed code change needing review | A pull-request or merge-request deployment preview | The deployment corresponds to the latest proposed change and the link has suitable access controls. |
| A longer-running set of changes | A branch deploy or staging environment | Reviewers know which branch or environment they are viewing, and review work cannot unexpectedly change production content. |
| Unpublished content from a headless CMS | Framework draft mode, where supported | Draft access is protected and the rendered page uses the intended CMS data. |
Compare candidate workflows by what triggers them (editor, local server, branch, or pull request), whether CMS drafts appear, who can access the URL, how closely the environment matches production, and how updates reach the preview. Netlify documents local development, branch deploys, Deploy Previews, and Preview Servers as distinct options; its connected-repository workflow can create a unique Deploy Preview for a pull or merge request. The best fit depends on your stack and access needs, not on the word “preview” in a product label.
Prepare the right version of the site
A preview can look polished and still be the wrong preview. Before reviewing appearance, confirm that it contains the intended change and data.

- Identify the change and its source. For an edited page or CMS item, open that draft’s preview. For code, start the project’s local server or create a branch or pull-request preview through the hosting workflow.
- Check a change-specific detail. Look for the updated sentence, image, component, or CMS field rather than relying on the page merely loading. Confirm that any unpublished content is actually present.
- Check the environment and data source. If the page uses a CMS, verify that the preview environment is configured to retrieve the expected draft data. Netlify’s Preview Server guidance starts with running the site locally using
netlify dev; a CMS-backed site may also need development connection parameters changed so it returns updated and unpublished content. - Confirm the revision. For a branch or pull-request deployment, check that the preview reflects the latest change you meant to review. If edits were pushed after a preview was created, wait for or trigger the updated deployment according to your host’s workflow.
For headless CMS sites, a framework’s draft mode can render unpublished CMS content with the site’s normal styling and layout. Vercel’s documentation, last updated September 24, 2025, identifies Draft Mode support for Next.js and SvelteKit and distinguishes it from preview deployments. Draft mode and a deployment preview solve related but different problems: one is about showing unpublished content; the other is about previewing a deployment.
Review desktop, mobile, and visitor-facing behavior
Do not treat a page that looks right in the editor as a completed review. Check the page at the screen sizes your audience is likely to use, then interact with it as a visitor would.
- Layout: inspect the whole page at desktop and mobile widths. Look for clipped text, unexpected wrapping, awkward spacing, missing images, and elements that overlap.
- Navigation and links: open important menu items and follow key links. Confirm destinations and labels are correct.
- Forms and controls: test the relevant inputs, buttons, menus, and other interactive elements in the preview environment. Do not assume an editor’s controls behave like site controls.
- Visitor view: hide editing controls if the platform allows it. Squarespace’s help documentation, last updated April 13, 2026, describes full-page preview and mobile appearance checks using its app; for version 7.1, it says closing the editor hides the editing toolbar and permits visitor-like interaction.
- Content states: check the page with the actual draft text and media, not just placeholder content. Long headings, empty fields, and missing images can change the layout.
Preview capabilities vary by platform, and a preview environment may not reproduce every production integration or setting. Use it to review the change in context, then check any behavior that depends on live services using the project’s appropriate test process.
Check who can access the preview before sharing
A preview URL is not automatically private just because it is not linked from the public site. Netlify’s documentation says Deploy Preview and branch URLs can be accessed by anyone with the link unless password protection or team login is configured. Treat an unprotected link as shareable: anyone who receives it may be able to view the page.
- Before sending a preview, determine whether access is open to anyone with the URL, limited to signed-in team members, or protected by a password.
- Use password or team protection when the content should be restricted, if your host offers those controls.
- Share the intended preview URL and identify the branch, draft, or environment it represents so reviewers do not mistake it for production.
- For headless CMS draft previews, protect the draft access mechanism as well as considering who can see the rendered page.
Do not infer privacy from an obscure URL, and do not share sensitive drafts through a link until you know how that platform’s access control works. Exact defaults and controls differ by host and can change; consult the current documentation for your setup.
Publish only after the review matches the intended target
Some platforms distinguish drafts, staging, and live publication as separate states. Webflow’s CMS API workflow separates staged drafts from live published content. Its help documentation describes publishing to a dedicated staging environment and recommends reviewing changes there before production. Before publishing, verify whether you are publishing the site, a particular CMS item, or both, and confirm the destination is production rather than staging.
- Review the correct draft or code revision in its preview.
- Check the visitor-facing page at relevant screen sizes and test the affected interactions.
- Confirm reviewers have finished and that the preview has appropriate access controls.
- Use the platform’s publish controls deliberately, confirming the target environment and scope before committing the change.
- After publication, open the live URL and verify that the expected content is visible. A successful preview review does not itself publish the change.
Platform interfaces and publishing controls vary. The examples here describe documented workflows, not hands-on testing; check the current help for the builder, CMS, framework, or host you use.

If you already have a preview URL reachable from the internet, ScreenshotNeo can capture it through one GET request. The API returns a PNG, JPEG, WebP, or PDF; use the response format appropriate to your review. It creates a screenshot of a URL—it does not create a CMS draft or deploy local code. For API parameters and setup, see the ScreenshotNeo documentation.

Common preview problems and how to fix them
| Symptom | Likely cause | What to do |
|---|---|---|
| The preview loads, but the new CMS text is missing. | The preview may be querying published content or using production CMS connection settings. | Check the preview environment’s CMS configuration and make sure it requests the draft data. Netlify’s Preview Server guidance specifically notes that development connection parameters may need to change. |
| A preview link opens for you but not a reviewer. | The reviewer may not have the required team login, password, or other access. | Check the URL’s access rules and grant the intended reviewer access or use the platform’s suitable protection setting. Do not disable protection for sensitive content just to make review easier. |
| The page looks different in the editor and preview. | Editor controls, viewport differences, or environment-specific data can affect what is visible. | Hide editor controls where possible, inspect desktop and mobile widths, and verify the preview’s data and environment before changing the live page. |
| A code preview does not include the latest edit. | The change may not have reached the branch or the preview deployment may not have updated. | Confirm the intended revision was pushed and check the hosting workflow for the current preview deployment before asking others to review. |
| A screenshot shows a consent banner or other overlay. | The capture may reflect what a visitor sees, while the overlay obscures the underlying page. | For a visual review, use a capture workflow that handles supported consent overlays, or inspect the preview directly and record whether the overlay is expected. Do not mistake overlay removal for proof that consent behavior is correct. |
FAQ
Can I preview a website that is only running on my computer?
A local development server is useful for reviewing your own code on your machine. To let a remote reviewer or a URL-based capture service reach a preview, use a deployment or another access method supported by your project; a machine-only local address is not the same as a publicly reachable preview link.
Does a preview URL mean the draft is already public?
Not necessarily: platforms can keep content in draft or staging while making a separate preview available. But the preview itself may still be viewable by anyone with its link, depending on access settings, so distinguish publication status from preview-link privacy.

No. A screenshot records appearance at a point in time. Approval of an interactive change should also include direct checks of the affected links, forms, navigation, or controls in the preview environment.
