The Chrome extension has stopped working. Instead of displaying information, it only shows ‘We are sorry, but…’ and it has been like this for several months. I delete it…

You can only view the data a few times a day, after that, they force you to log in… but when you do the layout of the website changes, AND THE INFORMATION YOU WANTED TO SEE IS NO LONGER VISIBLE

Do not use under any circumstances. It reads & analyses EVERYTHING you talk about with ChatGPT, Grok, etc

The extension break the pages. It overrides the fetch() method, but it doesn't do it right. A reproduction, run: """ const abortController = new AbortController(); fetch('https://mui.com', { signal: abortController.signal }) .then((response) => { if (!response.ok) { throw new Error(`Failed to fetch: ${response.statusText}`); } return response.text(); }) .then((output) => { console.log(output); }) .catch((error) => { console.log('error', error.name) }); abortController.abort(); """ with the extension loaded (it will throw) and without the extension (it will run normally).

Similarweb never loads for me, I am not sure if this is a ban or restriction on certain countries. Disappointed

Very few not very useful features for unpaid version. It is a PAID app.

Doesnt do anything. I downloaded the extension per the instructions and it does nothing. No help, no troubleshooting, no references on their site to help the issue

Very misleading. SimilarWeb tell you can track each page but you can't really - it only tracks the domain and subdomain, not individual pages - so yea not sure how they get away with false promises like this

Often tells that "my weekly limit is reached" despite I'm opening the extension for the first time in a month.

That was the worst experience I have ever had. With this extension, we only get 25 free uses per week. After that, we have to pay. However, the extension is still free.

So frustrating. Have tried re-installing, clearing cache, updating several times. No matter what every time I open the extension it shows the error page and says "Oops, something went wrong". Can't be used.

Does nothing after adding the extension. Looks like an expensive upsell product. Uninstalled. Waste of my time!

Extension does not work properly, and they want you to sign up for paid version. Don't bother downloading!

It was one of my favorites extensions, before They put limit on the extension, 15 websites per week or 25 if you have an account, that's not good at all

it keeps showing the message "you have used your free preview this month" - such a message has been there for 3 months and it is impossible to do anything or check the site statistics.

First was restricted to few requests. (defeats the purpose to see the indicator icon always?) Now doesn't seem to work anymore.

says I have reached weekly limit, I didn't use it even once this week. Also cannot register with google, it doesn't comply with google authorization rules

Used to be good, but no longer a free version. Not worth paying for with other comparable services that still offer it for free. Highly suggest looking at alternatives like: 1. Ubersuggest 2. Moz 3. SEOQuake

Yet another wonderful Chrome Extension resorting to greed with a stupid subscription. Will be uninstalling tonight, time to find another.

Does not find similar urls (sites) aka Does not do what it says it does. That is, it does not do what the MAJORITY of users expect it to do. Which is to utilize a similar site function. Which is what it used to do....YEARS ago and without incident. This not "neglect" but rather "intent".

The extension doesn't even let me click on the icon when I pin it.

It's NOT working on chrome. Please fix the issue. It doesn't even open when I click on it on the extension bar on chrome...

Keeps on showing no data for sites that are ranked in their own database. For example, the app shows the similarweb logo as half full but still shows that it has no data.

Riep for this extension. Very sad to write this review this most loving extension is now totally useless. I don't know why you it is now showing the traffic of all websites as it does in the past. please rebuild it currently it only show traffic of few huge websites.

Super time waster for copying and pasting a url into a field and processing it. That simple feature is gated until you jump through a bunch "pro feature" hoops. Warning: Time suck.
