Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

2.8

GPA, above 4 of the 34 other SEO browser extensions we grade

View Rendered Source is a small, free Chrome extension by Jon Hogg's Peg Leg Ltd that shows a page three ways: the raw HTML the server sent, the DOM after the browser and JavaScript have built it, and a line-by-line diff of the two. It is aimed at developers working with frameworks such as React, Angular and Vue, and at SEOs checking what search engines are served. The raw source can be requested as Googlebot or a mobile browser.

To get you started, here are 7 things to know about View Rendered Source, taken from its own pages and our grades.

No rating on record, but nothing to set up: open a page, click the icon and the three views are there.
From our grade for ease of use
  1. 1

    Best for comparing raw HTML with the rendered page

    View Rendered Source shows a page three ways, the raw HTML, the DOM after JavaScript has run, and a line-by-line diff of the two, and can fetch the raw source as Googlebot or a phone.

  2. 2

    It is free

    View Rendered Source has no paid plan at all. Free to install from the Chrome Web Store; the listing mentions no paid version, account or sign-up.

  3. 3

    Raw source

    The HTML sent from the server before the DOM is built, as the browser's own View Source shows it, lightly formatted.

  4. 4

    Rendered source

    The page after it has been turned into a DOM, including every change JavaScript has made to it.

  5. 5

    Line-by-line difference

    Highlights each line that differs between the raw and rendered versions, showing what JavaScript added or changed.

  6. 6

    A 2.8 GPA, above 4 of 34

    That is against the other SEO browser extensions we grade, on value, the free plan, features, ease of use and platforms.

  7. 7

    Keep it

    View Rendered Source is free, so making your own would save you nothing.

Best for comparing raw HTML with the rendered page

View Rendered Source shows a page three ways, the raw HTML, the DOM after JavaScript has run, and a line-by-line diff of the two, and can fetch the raw source as Googlebot or a phone. That's one narrow job, in Chrome only, and the last release was version 4.0 in June 2023.

ToolGPA report cardView Rendered SourceGraded Oct 23, 2026

FeaturesDOne narrow function: raw against rendered source with the differences highlighted, as Googlebot or a mobile browser if you like. No tags, links, schema or search data, and no audit.
Ease of useBNo rating on record, but nothing to set up: open a page, click the icon and the three views are there.
Platforms and integrationsCChrome only, so computers only, in English, with no website of its own and no integrations. Support is by X message to the developer.
Grade point averageGood, out of 4.02.8

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Who View Rendered Source is for

  • Fits if you check what a JavaScript-heavy page looks like before and after rendering
  • Works for developers testing prerendering or dynamic rendering for Googlebot

Who it is not for

  • Watch out: the last release, version 4.0, is from June 2023
  • Skip it if you're not on Chrome, as there's no other version
  • Too light for audits, since it compares one page's source and checks nothing else
  • Not for you if you want a help page, as support is by X message to the developer

Good to know

Good for

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

Keep it

View Rendered Source is free, so making your own would save you nothing.

That makes this kind of software worth paying for, not this one in particular: 18 of the 34 other SEO browser extensions grade higher.

What you could not

  • A crawler that checks every page of a site.

What this rests on. View Rendered Source’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
