Chrome can take screenshots. Most people don't know this because the feature is buried inside DevTools, but it's there. So why would you install an extension when Chrome already does it?
Fair question. We used the DevTools method for a long time before building VZLyze, so we know both sides of this pretty well. The short answer: Chrome's tool works for simple one-off captures. For anything beyond that, it starts to fall apart.
Here's a direct comparison.
Capture modes
Chrome's DevTools gives you two screenshot commands: "Capture screenshot" (visible area) and "Capture full size screenshot" (entire page). Both are accessed through the command palette (Ctrl+Shift+P inside DevTools).
VZLyze has three modes: Visible, Full Page, and Selection. The first two do the same thing as Chrome's commands. Selection lets you drag a box around a specific part of the page and capture just that. Chrome doesn't have an equivalent.
The bigger difference is how you access them. Chrome requires you to open DevTools first, then open the command palette, then type the command name. VZLyze is one click in the toolbar. If you're taking screenshots regularly, the extra steps in DevTools add up.
The sticky header problem
This is the one that pushed me to build something different.
When Chrome captures a full-page screenshot, it scrolls through the page internally and stitches the sections together. The problem is that sticky headers and fixed navigation bars get captured at the top of every section. So if the page has a sticky menu, you'll see it repeated throughout the image, sometimes five or six times on a long page.
VZLyze handles sticky elements differently. It detects fixed-position elements and keeps them from duplicating in the final image. The result is a clean capture that looks like the actual page, not a bunch of glued-together viewports.
This matters more than you'd think. If you're sharing the screenshot with someone, repeated headers make it look broken. If you're archiving the page for reference, it's just messy.
Export options
Chrome gives you a PNG file. That's it. No other format, no metadata, no options.
VZLyze gives you PNG download and PDF export. The PDF includes the source URL and capture date, so you have context when you look at it later. If you ran AI analysis on the screenshot, that gets included in the PDF too.
For quick personal captures, PNG is fine. For anything you're sharing with a team or keeping for documentation, the PDF is more useful.
AI analysis
Chrome's screenshot tool captures pixels. That's where it stops.
VZLyze can analyze the screenshot after capturing it. The AI reads the content, pulls out the key information, and gives you a structured summary. You can also run a Research Mission that goes beyond the screenshot and searches the web for related context.
There's also a Compare mode where you can put two screenshots side by side and have the AI identify what changed between them. Useful for tracking page changes over time or comparing two versions of a design.
These features use credits, so they're not free. But the capture and basic export are.
Side-by-side summary
| Feature | Chrome DevTools | VZLyze |
|---|---|---|
| Visible area capture | Yes | Yes |
| Full page capture | Yes (sticky header issues) | Yes (clean output) |
| Selection capture | No | Yes |
| Access | DevTools command palette | Toolbar icon, one click |
| PNG export | Yes | Yes |
| PDF export | No | Yes, with URL and date |
| AI analysis | No | Yes (uses credits) |
| Screenshot comparison | No | Yes |
| Price | Free | Free (AI uses credits) |
| Requires DevTools | Yes | No |
When Chrome's tool is enough
We don't want to pretend the built-in tool is useless. There are situations where it's perfectly fine.
If you need a quick visible-area screenshot once a week and you don't care about format, Chrome works. If you're already in DevTools for debugging and you want to grab the current state of the page, it's right there. And if you prefer not to install extensions at all, it's the zero-install option.
But if you do any of the following, you'll probably hit its limits fast: full-page captures of pages with sticky headers, sharing screenshots as PDFs, capturing specific regions, analyzing what's in the screenshot, or taking screenshots often enough that the DevTools workflow slows you down.
Bias disclaimer
We built VZLyze, so obviously we think it's better. We tried to keep this comparison factual, but you should know where we're coming from. If you want to test both, VZLyze's capture and PDF export are free, so you can compare the output directly without paying anything.
