invisible_playwright vs nodriver and undetected-chromedriver

These two are one lineage, not two separate comparisons. undetected-chromedriver patched Selenium’s chromedriver binary to stop Chrome announcing itself as automated. nodriver, from the same author, is its successor: it removes the chromedriver binary and the WebDriver protocol entirely, and speaks the Chrome DevTools Protocol directly.

The comparison with this project is unusual for a reason worth stating up front: these are not Playwright tools. They have their own API. That changes what “choosing between them” actually means.

What they are, and the thing that makes this comparison different

Every other tool on this site’s comparison pages is a Playwright fork or a browser you launch through Playwright. nodriver and undetected-chromedriver are neither. Their own documentation is explicit: nodriver’s pitch is “no more webdriver, no more selenium,” with its own async interface and its own methods (tab.find(), tab.select(), tab.xpath()). There is no page.goto() here, because there is no Playwright underneath it.

So the decision is not “which of these two produces a less detectable browser.” It is whether you are willing to leave the Playwright ecosystem at all. If your project has existing Playwright code, page objects, or test infrastructure, adopting either of these means rewriting the automation layer, not swapping a launch call the way most of the tools on this site’s comparison pages let you.

What undetected-chromedriver actually patches

Selenium drives Chrome through chromedriver, a separate binary, and that binary used to leave literal tells in the page: a global variable named after the string cdc_, placed there by the driver itself. Early versions of undetected-chromedriver removed and renamed that variable; later versions changed approach and instead prevent the tell from being injected in the first place, which the project’s own changelog frames as the more robust fix. We cover the same variable, and why renaming beats removing, on our own version of this problem - it turns out the exact lesson generalises past Selenium entirely: a tell you rename is still a tell if its presence is what gets checked, not its name.

What nodriver changes by dropping the binary

nodriver’s argument is that removing the chromedriver binary and the WebDriver protocol removes an entire category of tells at once, rather than patching them one at a time. Talking to Chrome over CDP directly, with no intermediate driver process, also removes a process-tree and port signature that a patched driver still has to explain away. Its own documentation frames the performance gain as a side effect of the same architectural change, not the point of it.

What neither one claims to touch

Both projects are unusually direct about their own scope, more so than most tools in this space, and it is worth taking them at their word rather than assuming more. undetected-chromedriver’s documentation states plainly that the package does not hide your IP address and does not handle device fingerprinting. Nothing in either project’s documentation claims to change the GPU string Chrome reports, the fonts it enumerates, the canvas output, or the audio pipeline. That is a different layer of the problem, the one Camoufox and this project work at instead, and pairing a CDP-native driver with separate fingerprint work is the normal pattern for people using either of these two.

The engine question these two do not raise, and the one they do

Both drive Chrome or Chromium specifically, which puts them in the same Chromium-is-not-Chrome position as any Playwright-Chromium launch: the default binary lacks the proprietary codecs a real Chrome install has, and using either tool does not change that on its own. Where these two differ from a Playwright launch is that they are commonly pointed at an existing installed Chrome binary rather than a downloaded Chromium, since neither ships a browser of its own the way Playwright bundles one; if you point either at a real Chrome install, the codec gap does not apply to you in the first place.

If your target needs Firefox rather than Chrome for other reasons - four structural ones are covered here - neither of these tools is relevant regardless of which one you’d otherwise pick, since both are Chrome/Chromium-only by design.

How to actually choose

Have existing Playwright code and don’t want to rewrite it? Neither of these. Stay in Playwright and pick a tool at the layer you actually need, from the three-level map.
Starting fresh, committed to Chrome, and comfortable with a new API? nodriver is the actively developed one; undetected-chromedriver is the older, Selenium-based lineage it replaced.
Need the fingerprint layer solved too (fonts, GPU, canvas, audio)? Neither claims to do this, by their own documentation. Pair either with something at that layer, or use a tool that already covers both.
Need Firefox? Off the table for both; they are Chrome/Chromium tools specifically.

Conclusion

undetected-chromedriver and nodriver solve the same problem this project solves at the Playwright-driver layer for Camoufox and its comparisons, but they do it by leaving Playwright’s API entirely rather than patching around it. That is a real cost if you have existing Playwright infrastructure, and a real benefit if you are starting fresh and want the shortest path to a CDP-native Chrome. Neither claims the fingerprint layer, and their own documentation says so.

Short answers to the questions that lead here

Are nodriver and undetected-chromedriver Playwright tools? No. Both have their own API and do not run through Playwright at all.

Is nodriver a replacement for undetected-chromedriver? Yes, from the same author, dropping the chromedriver binary and the WebDriver protocol in favor of talking CDP directly.

Do these fix browser fingerprinting? No, by their own documentation. They address the automation-driver layer, not fonts, GPU, canvas, or audio.

Do they hide my IP? No. undetected-chromedriver states this explicitly; treat proxy and IP handling as a separate problem for either tool.

Can I use Firefox with either? No, both are Chrome/Chromium-specific.
