  • Manifest V3
  • Analysis runs locally

Built for developers, designers, QA teams and WordPress professionals. Website access is limited to normal HTTP and HTTPS pages.

Pro on a real page

See every Pro tool work on an actual website.

We opened a demo coffee shop site at a 390 × 844 phone viewport and ran SiteMorphix Pro on it. The findings, repair result and scores below are exactly what the extension measured.

Deep audit

Find exactly what breaks on a phone.

The audit scans the rendered page and flags every element that pushes content past the screen, with the reason for each one.

  • 51 / 100
  • 21 horizontal overflow candidatesHigh
  • 8 oversized fixed-width elementsMedium
  • 2 overflowing flex containersMedium
  • 2 nowrap overflow candidatesMedium
  • 1 oversized media elementMedium
  • 1 wide tableLow

Verified repair

Apply a reversible repair, then prove it worked.

SiteMorphix changed 16 elements on the live page, measured the layout again and reported the result. Nothing was saved to the site; Undo all restores the original instantly.

Live translated preview

Pick a language and see the same site translated.

Choose a language and SiteMorphix opens the page in a calibrated preview window, translated, with the right direction. Arabic and Hebrew flip the whole layout to RTL.

Pro capabilities

Built around the problems that slow front-end QA down.

Each tool has one job: make responsive compatibility easier to inspect, understand and hand off to development.

Verified responsive repair

Repairs common overflow sources: fixed and min widths, oversized media, embeds, tables, forms, long text, flex and grid overflow, negative margins and selected positioned elements. Each result is classified as Verified Fixed, Improved, Applied with manual review, or Issue remains.

Bootstrap compatibility

Detects existing Bootstrap context, highlights legacy patterns and avoids layering a second framework over an existing installation.

Live LTR / RTL device preview

Open the active site in a calibrated phone, tablet, laptop or desktop preview with Auto, LTR or RTL direction. The original page is never permanently changed.

Live translated preview

Pick a supported language and open the active site in a translated device preview, using Chrome's built-in on-device Translator API where the language pair is available. Requires Chrome 138 or newer.

Developer exports

Export audit JSON, responsive CSS starters, translation dictionaries, Bootstrap migration notes, RTL/LTR starters and HTML setup guidance.

Undo-safe workflow

Try repair ideas in the browser first, then make permanent changes in your source code, theme or CMS.

Free vs Pro

Start free. Upgrade when you need deeper repair and audit tools.

The Chrome Web Store build covers responsive device testing. Pro adds advanced compatibility work.

Workflow

From broken breakpoint to clear next step.

SiteMorphix helps you inspect, test and hand off fixes safely, without pretending browser previews are permanent server edits.

  1. Open the real page

    Use SiteMorphix on the current Chrome tab and test the layout at common device targets.

  2. Audit, repair and verify

    With Pro, scan the rendered page, apply selected reversible repairs and compare before/after measurements with a final Verified Fixed, Improved, Manual review or Issue remains status.

  3. Export and implement

    Use the generated report and starter patches to make permanent changes in your source code, theme or CMS.

Privacy-first architecture

Website access for responsive testing, nothing more.

SiteMorphix can inspect normal HTTP and HTTPS pages so previews and audits work without repeated per-tab prompts. Analysis runs locally in the browser, and Chrome internal and other protected pages remain inaccessible.

FAQ

Questions before you install.

Still unsure? Contact support or read the documentation.

What does SiteMorphix Free do?

Free focuses on responsive website testing in Chrome with common device viewport targets, orientation testing and viewport context.

Does SiteMorphix permanently modify websites?

No. Preview and repair actions work on the rendered page in the browser. Permanent changes still belong in your website source code, WordPress theme, page builder or another authorized server-side workflow.

What is added in SiteMorphix Pro?

Pro adds deeper responsive audits, verified reversible repairs with before/after measurements, Bootstrap compatibility checks, live LTR/RTL device previews, live translated previews for supported language pairs using Chrome's built-in Translator API, translation-ready extraction and developer-focused exports.

What does the repair status mean?

SiteMorphix reports Verified Fixed when the measured issue is resolved, Improved when the measurement gets better but remains, Applied - manual review needed when the browser-side change was applied but cannot be fully verified numerically, and Issue remains when the measured problem did not improve.

How does live translated preview work?

Choose a device preset, Auto/LTR/RTL direction and a supported language. SiteMorphix opens the active website in a separate calibrated preview window and applies supported translation in that preview. The original page is not permanently edited. This feature requires Chrome 138 or newer and a supported Chrome Translator API language pair; Chrome may download a language pack on first use.

Can it work with WordPress websites?

Yes. SiteMorphix works with the rendered website in Chrome, so it can be used while testing WordPress, static HTML, Bootstrap and many other front-end stacks.

Does Bootstrap mode replace my existing framework?

No. The Pro workflow first checks the current page context and is designed to avoid blindly layering a second Bootstrap framework over an existing installation.

How will Pro licensing work?

SiteMorphix Pro is planned to use Freemius for checkout and licensing. That integration will be connected separately before paid launch.

SiteMorphix 1.0.0

Build responsive confidence into every release.

Use Free for faster breakpoint testing. Use Pro when the job needs deeper auditing, verified reversible repairs, live translated LTR/RTL device previews and implementation-ready exports.
