Confirmed with Chrome and even Firefox on MacOS/Windows 11.

I'm having the exact same issue. Doesn't matter if closing the devtools in Edge or Chrome, both show the exact same behaviour as described by the reporter. Any help on this?

Because this topic has not yet been addressed by the developers, I have found a rather primitive but temporary solution: refreshing the page whenever the DevTools are closed. I have discovered that refreshing the page "resets" the memory leak. To automate this reload event, I have created a simple Chrome extension (currently under review) that does this for me, but only on specific websites (e.g., localhost).

Extension as zip file:
refresher.zip

Seeing same problem in Brave on my Mac:

MacOS version: 14.1.1 (23B81)
Brave version: 1.60.118 Chromium: 119.0.6045.163 (Official Build) (arm64)
Vue devtools version: 6.5.1

Having this issue also. For me I do have to open and close the dev tools at least 2 times.

1. open devtools.

2. Go to Vue tab.

3. Close dev tools.

4. Open devtools.

5. Go to vue tab.

6. Close dev tools.

Memory will then increase by about 100 mb every 1-2 seconds, and will not go down.
im using Brave browser on Windows 10.
Extension version 6.5.1
Brave version 1.60.125

any solutions yet ?

Same, vue devtools are unusable for me as of a few weeks ago. Switching routes takes 3 seconds of freeze.
EDIT: I use Vuetify and noticed that v-img causes slowdowns when used with devtools.

Experiencing the same with devtools 6.5.1 and latest chrome Version 120.0.6099.216 (Official Build) (x86_64)
Using firefox on the other hand works perfectly fine for me with 6.5.1 extension and firefox at 121.0.1

I am running the latest MacOS too

What I observe that it'll only freezes browser only if we close inspect tool window. If I not closing an inspect then vue tool works fines but after closing browser inspect it'll freezes so keep open your inspect tool

Affirmative.
In my case everything works fine until the hot reload is triggered. As soon as I change something in my code, it updates and I reload the page, the browser freezes intentionally.
I noticed in the htop output that one of the cores is 100% loaded at that point
Developers, please give feedback on this problem! Using chrome for vue development has become extremely difficult (if I need vue inspector, I have to open Firefox...).

Fedora 38
Kernel 6.5.5-200.fc38.x86_64
Version 121.0.6167.85 (Official Build) (64-bit)
Vue Devtools 6.5.1
Gnome 44.8 with Wayland

Can not use it... if you open it, it crashes chrome...

Do vue developers never use it? Why can such a serious problem exist for so long?

any solutions yet ?

I created this basic chrome extension tool that gives a temporary solution:
https://chromewebstore.google.com/detail/devtools-close-refresher/nfcfibfdokdooefjclehlhgojpmchlhp?hl=en-GB&authuser=0&pli=1

I'm seeing a similar thing using Chrome inspector and Vue dev tools the memory usage would increase really quickly, it's unusable for me at the moment. Chrome task manager reported the tab was using up to 8gb and then tab would crash.

Refreshing the tab didn't work very well for me either.

I've disabled Vue dev tools extension and memory usage is normal.

Ubuntu Linux 22.04
Chrome 121.0.6167.184
Vue Devtools 6.6.1

Project is using Vue3 with Vite 5.1.1

I have this issue on mac os Version 14.1.1 .
When vue devtools is open Ram usuage is increase until freezing chrome.

Maybe this will help someone.
Recently devtools has been updated to 6.6.1, maybe the problem has been fixed. Unfortunately I didn't have enough time to verify it
If you are still getting the problem you can try the following:

1. Download the 6.4.5 release (https://github.com/vuejs/devtools/releases/tag/v6.4.5)
2. Build and install the extension manually

I have this bug clearly disappeared in the 6.4.5 release.

P.S. I would like to say thanks to the developers for not abandoning this project

I downloaded this version but when i want to add in load unpacked extension got this error :

Failed to load extension
File
~/Downloads/devtools-6.4.5
Error
Manifest file is missing or unreadable
Could not load manifest.

I failed to get older versions working, one work-around that's working for me is the stand-alone app.

That hasn't shown any problems yet - seems speedy.

I don't know if it's when it closes or not, but I have the same problem, Chrome constantly freezes on Mac. This makes for a horrible experience, I have to force quit all of Chrome every 5 minutes

6.6.1 has still same memory leak issue. Edge freezes and memory starts to increase by Gigabytes

the same, Chrome, Windows

Chrome keeps on freezing after opening Vue Devtools for some time. I have to check Vuex store values like this for now:

Array.from(document.querySelectorAll('*')).find(e => e.__vue__).__vue__.$store.state

Also experiencing something similar. Immediately after opening vue devtools, the memory usage would start quickly going up to 20+ gb until chrome would just crash. I only got a 20-30 second window to use the devtools.

What seems to have helped is disabling React Devtools, Angular Devtools and other extensions.

v6.6.1 reproduces

I disabled Angular devtools and everything gets ok.

Thanks a lot my friend, after 6 month finally my vue devtools is working.
