Claude in Chrome is the best debugging tool I could ever ask for

But with the more recent announcement of Claude in Chrome, the tool has now become an absolute go-to for development. I'm saying this because, before this, if you were designing something or trying to point out a design bug, a front-end bug, or pretty much any issue with the UI, you had a couple of options. You could ask Claude to inspect the code and try to figure out what was wrong from there, or you could share screenshots of the issues you were seeing and explain what needed to be fixed. And if you needed to do this repeatedly, you could set up some kind of automation using Playwright, where you'd have a routine that opens the application, takes screenshots, and verifies different states of the UI. But all in all, this process has always been pretty cumbersome. With Claude in Chrome, you can basically allow Claude to visit the same front-end you're looking at, inspect what is actually happening in the browser, figure out what is wrong, make the necessary changes in the code, and then come back and verify whether the fix worked. Claude in Chrome is a game changer for debugging Claude can now actually see what's wrong Earlier, your flow would usually be that Claude Code writes the application, you run it in Chrome, and Claude understands what is happening primarily through the code itself. If you're able to see that something is misaligned or visually off, you then have to explain it to Claude or paste a screenshot. For example, there have been many times when I've asked Claude to build something, maybe a landing page or the UI for a feature, and technically it builds what I asked for, but something just looks wrong. Sometimes a button isn't centered, the spacing is off, or the text gets truncated. Sometimes an element overflows its container or a layout looks fine on one screen size but completely breaks on another. With Claude in Chrome, you can simply ask Claude to take a look at the application itself and work out what needs to be fixed. And it goes far beyond design issues. Claude can inspect console errors, network activity, and the DOM state. It can navigate through your application, click buttons, fill in forms, move through different screens, and observe what happens after each interaction. Let's say you've built a login flow and clicking the login button doesn't do anything. Earlier, Claude would inspect the authentication code and try to reason about where the problem could be. Now it can actually open the application, fill in the form, click the login button, see whether an error appears in the console, inspect whether the API request failed, check what the browser did afterward, trace that problem back to the code, fix it, reload the application, and test the whole flow again. It also works really well for design verification You can use it to replicate a design Claude in Chrome isn't just useful for debugging. It also works really well when you want to replicate a design. For example, if you want Claude to build a landing page similar to those of your competitors, you can ask it to go through their actual websites. You could even have it analyze multiple competitors and then implement what each of them does best. As I mentioned above, you can keep asking Claude to visually verify the design until it gets it right. The only caveat is that Claude in Chrome consumes a lot of your usage allowance, so verifying something multiple times can eat through your usage limit very quickly. Of course, Claude in Chrome doesn't make tools like Playwright unnecessary. For deterministic regression testing, where you want the same tests to run automatically every time you push code, Playwright still makes a lot of sense. Claude in Chrome works with logged-in apps My personal favorite feature My favorite feature, though, is probably the fact that Claude in Chrome works with the accounts you're already logged into. A lot of the apps you actually need to test are dashboards, admin panels, internal tools, staging environments, and CRMs, which aren't publicly accessible. And getting an agent into those environments otherwise is a huge pain. You either need to give it access through an API, set up some integration, figure out authentication for your browser automation, or deal with sessions, cookies, SSO, and sometimes MFA. Claude in Chrome basically skips that problem because it works inside your existing browser session. If you're already logged into the application, Claude can work with the page in front of you using that same login. Anthropic specifically calls out internal tools, legacy portals, admin consoles, and other systems without APIs as use cases for this. So you can open your app, log in normally, and then tell Claude to go reproduce the issue. ChatGPT also has the same feature If you are not using Claude, which I understand because the usage limits are insane, ChatGPT also offers the same feature through its browser extension. It works in a similar way, but you get better usage limits.
