Stack Apps is a question and answer site for apps, scripts, and development with the Stack Exchange API. It's 100% free, no registration required.


Stack Exchange Notifier is a handy extension for Google Chrome browser that displays your current reputation, badges on Stack Exchange sites and notifies you on reputation's changes. You will now get notified of comments on your own posts (questions and answers) and of any comments that refer to you by @username in a comment, even if you do not own the post (aka mentions). All StackExchange sites are supported.

Follow Stack Exchange Notifier on twitter to get notified about news and updates:


Written in Java, Google Web Toolkit under Eclipse Helios.
Stack Exchange Notifier uses the Stack Exchange API and is powered by Google App Engine for Java.


I will be porting extension to not use app engine back-end due to some limitations. New versions of the extension will be making direct calls to Stack Exchange API right from your browser. Please do not expect new versions of the extension any time soon. Sorry.

Any suggestions for improvements/features to add?

Why does it require a Google login? –  Dennis Williamson Sep 16 '10 at 14:37
@Dennis, This extension requests your reputations, badges, etc not directly from stack exchange api endpoints, but using its backend to request data in batch. It tracks associations between you and your stack exchange accounts in datastore and uses OpenID to confirms your identity. Now it supports only Google, but I will add other OpenID providers soon. Let me know if you feel that something is not right with this approach. At least it allows you to run extension on any number of computers. –  Vladislav Tserman Sep 16 '10 at 15:21
I tried it out... works great! –  Nathan Osman Sep 21 '10 at 6:08
Nice & very useful extension... Thanks... –  chanchal1987 Sep 23 '10 at 8:42
Why do I have to connect with my Google account and then manually add my site accounts whats the point of the initial log in? Also it doesn't work, trying to add an account gives Oops! Something went wrong while processing your request. –  Jonathan. Oct 6 '10 at 17:52
because as I know, there is no possible way in API to search of user records by email hash. Read more…. @Jonathan, thanks that you noticed this problem, if you see possible ways how to improve this initial process please let me know. As concerning problems with linking your accounts, please try again, sometimes errors happen. Also check that you are using latest version, released on Tuesday, October 05, 2010 –  Vladislav Tserman Oct 6 '10 at 18:55
So why do I have to login with openID at all? Cant I just enter my profile number. I downloaded it about 5 minutes before posting –  Jonathan. Oct 6 '10 at 20:28
I thought I already answered this question before, but ok, probably you are right and this should be optional for those people who want synchronize settings between different browsers/computers. Did you managed to add your accounts? –  Vladislav Tserman Oct 6 '10 at 20:55
yes it just did 3 seconds ago, but before that it gave just a 0 as an error. –  Jonathan. Oct 7 '10 at 17:01
btw, it showed both the parent and the meta accounts, arent they the same account? Anway –  Jonathan. Oct 7 '10 at 17:21
Anyway, on the list of questions/etc next to the question it shows a number, for me it was 5 and 5 and 10 but I couldn't see where that number came from. –  Jonathan. Oct 7 '10 at 17:27
Awesome extension, keep the good work! Hope to see it back at full throttle soon. :) –  Cawas Jan 5 '11 at 12:57
It looks like the extension stopped working around yesterday; the pop-up page is just blank. Is there something wrong with the GAE instance? I miss it already :( –  Adrian Petrescu Feb 12 '11 at 1:36
@Adrian I'm seeing the same thing - are you using the Chrome dev version? (I'm at 10.0.648.45) –  Jared Harley Feb 13 '11 at 18:46
The issue I get is "Something went wrong while processing your request" after validating with google, and nothing loads up. Vlad, maybe you also want to get in touch with this guy: you should definitely talk and get to a common place with your two lovely extensions! :D –  Cawas Feb 14 '11 at 18:13

I'm new to SEApps, and given the design of it, I apologize if bug reports are not supposed to be "Answers". Please let me know and I'll move it to the OP comments.

That having been said, I just installed this extension, and have a problem. Why can't I manually specify an OpenID in the extension configuration? I don't use a common vendor, I have my own.

You are not alone with such problem. I've already answered question from user on following page In future versions I will eliminate need of OpenId login (It will be required just to synchronize extension settings between computers) –  Vladislav Tserman Nov 8 '10 at 16:50
Unfortunately, this extension is useless without the ability to specify an OpenID provider. –  Chip Bennett May 31 '12 at 15:12

I think it is better to change the title of the "username" from "username" to "site name" in the "Accounts" page. It will help peoples to understand the site name easily.

share|improve this answer
Thanks for feedback. It will be ready by the end of the week in Version 1.2.9. The title will show something like '@Username on StackOverflow'. –  Vladislav Tserman Sep 23 '10 at 9:29
Version 1.2.9 released! –  Vladislav Tserman Sep 25 '10 at 1:07
@Vladislav Tserman: Another feature to include in the next version 1.3 (not mentioned in this<…; page): play notification sound. –  chanchal1987 Sep 25 '10 at 10:40
@Vladislav Tserman: And another feature to include is "Remember me" checkbox in the login page. –  chanchal1987 Sep 28 '10 at 5:35
Icons not working on os 10.8.3, Chrome (latest) –  Buscar웃 Apr 15 '13 at 21:21

This is a very slick, awesome-looking extension with lots of potential.

My main feature request would be for the ability to be notified of changes to any question (not just your own), the way that StackStalker does it. This would be great since it looks like StackStalker's author has lost interest in it and hasn't added support for arbitrary Stack Exchange sites yet.

Keep up the great work!

thanks for your feedback, glad that you like it. Configurable notifications of new questions and of changes to any question you like on Stack Exchange network sites is first in my todo list for next major update. –  Vladislav Tserman Oct 6 '10 at 13:37
That's really great to hear :) I'm looking forward to my Stack Exchange Notifier notification of updates to this question, then ;) –  Adrian Petrescu Oct 6 '10 at 13:38
i haven't lost interest, i just haven't had the time! haha... i definitely want to support all SE sites :) –  Jason Oct 20 '10 at 21:02

Two problems that I have:

  1. My display username is "Nomæd" with a unicode letter æ, but it appears as �� instead.
  2. I have 6 associated accounts, and the main one is but I can't make it appear in my list of accounts in any way.

Anyone has solutions, mainly for problem no. 2?

I've just finished 2-month contract project and ready to address accumulated issues with extension. –  Vladislav Tserman Dec 25 '10 at 13:18
Great news! :) Thanks Vlad. –  Nomæd Dec 25 '10 at 14:43

Hmm, needz moar escaping: My notifications for the question Implement <!— language: lang-css --> in preview are showing as "Implement in preview"!

I tried to log-in but Google says that there is a new OpenId standard as:

Please fix!

Pretty sure this app is way obsolete and no longer supported. You'll probably have to fork the source and fix it yourself. –  Brock Adams Apr 29 at 5:10

I know you just posted this:

I will be porting extension to not use app engine back-end due to some limitations. New versions of the extension will be making direct calls to Stack Exchange API right from your browser. Please do not expect new versions of the extension any time soon. Sorry.

Currently, you may experience some issues using extension, but most users will have no problems. You may notice too many errors in the logs, but there is nothing I can do with this now. Thanks for using my little app.

but I thought I would let you know that I am having to re-authenticate every time I log in (and sometimes when I've already been logged in for a while). I use OpenID, and after telling OpenID to remember me, it's just a matter of clicking on your icon, clicking the OpenID button, and then waiting for the page that says "Yaay, we're logged in!"

Otherwise, I absolutely love it! It looks nice and works well. I especially like that comments have part of the text (and all of it on hover). Thanks for all your hard work!

glad that you like the extension. In future versions I will completely eliminate need of OpenID for login (It will be required just in order to synchronize extension settings between computers). –  Vladislav Tserman Oct 22 '10 at 1:19

The escaping issue has been mentioned already, but I'd just like to accentuate it with a screenshot -

As you can see, the HTML is actually being rendered. In the case of an HTML comment, the content is simply not displayed, but HTML content here is being showed as an un-ordered list item.

Here is a link to the post from the screenshot.

Doesn't work in Linux.

Yep, just as the title says, this extension is absolutely, 100% non-functioning on Linux.

After installing, I clicked on its icon, signed in, and saw this success message:

Congratulations, you've been successfully authenticated. Enjoy Stack Exchange Notifier!

Stack Exchange Notifier authorized!

...but the icon still has the red question mark on it.
Attempting to re-authorize just opens an empty tab.

If I restart the browser, I can (try to) sign in again, and am greeted with the same "success" message, but get the same results as before.

For the first time in my life I used Facebook integration to login to stackoverflow, and what a surprise, I can't use it because I don't see how to configure it with it.

I had to uninstall.
