I honestly can’t believe it took me this long to leave a review. I’ve been using this extension for a few months now, and it’s one of those extensions I keep coming back to without even thinking about it, it's become part of my workflow. I’m literally in the middle of a technical audit right now and after using it for the umpteenth time tonight, I had a moment of realization... how have I not reviewed this yet?! It's easy to use, fast, and efficient. Great extension!!!
Fantastic. Use it at least weekly for something. Something that was always irritating is now significantly less so
If you work on JS-driven sites, this extension is a lifesaver for technical SEO audits. Comparing raw response HTML to the fully rendered DOM makes discrepancies jump out immediately, so you can spot content that’s only appearing (or disappearing) after JavaScript runs. It’s also one of the easiest ways to visually explain commons JS issues at speed. I love pulling this tool up on (non-technically minded) client calls to show them what is happening behind the curtain.
This plugin’s the fastest, most intuitive free way to see how JavaScript changes what bots see when crawling any page, on any site — zero configuration required!
As someone who audits JS-heavy sites for Enterprise businesses, this extension has become an essential part of my SEO workflow. The way it visually compares static HTML against rendered output is brilliant. You instantly see what’s being injected or lost through JavaScript. It’s also been great for client communication; showing them exactly where visibility gaps occur has never been easier. The clean interface (Response/Rendered HTML) make it a must-have for any serious technical SEO.
By far the best plugin to find differences between initial HTML response and fully rendered webpage. Very clear layout makes it easy to find the differences in content, links, and HTML.
This extension is critical to my every day work. It allows me to review what is being added in via Javascript, specifically highlighting SEO related elements (title, meta, robots, canonical, body copy) for easy viewing and auditing.
This tool quickly surfaces JS-related rendering issues. It clearly flags differences in metadata, headings, and links—I used it to show a client their headings and links were missing in static HTML. It also made dev QA easier. I’m still learning it, but it’s already saving time and proving useful.
As the web continues to evolve, understanding the way different methods of build can impact our visibility continues to become more and more important. This tool allows SEOs and other website stakeholders to understand how Javascript rendering can handicap a website's visibility, and that is such an important consideration these days. In their typical fashion of understanding the needs and questions of the industry, Gray Dot nailed this.
This is an extremely useful tool! Just tried it, just works. Great UI/UX. SEOs can easily identify what parts of the page is visible to bots only after JS rendering.
