I get Chrome notifications from several websites and they work when I don't even have any tabs open for those sites.
But sometimes I get these Chrome notifications when I am not at my desk or looking at my laptop.
As some of these notifications are useful to me, I would like to be able to access any that I have missed.
Is there a way to view the notification history?
If you have a Mac, there is a way!
Here's how the notifications list would look like:
All you have to do is:
1. In chrome, go to:
chrome://flags/
2. Look for:
Enable native notifications. Mac
3. Enable it, restart chrome, you are done. Enjoy!
EDIT:
Starting in Chrome 59, notifications sent via the Notifications API or the chrome.notifications extensions API will be shown directly by the macOS native notification system instead of Chrome's own system. [source]
On MacOSX you will have Chrome directory located in Library/Application Support. Open terminal application and run next commands:
cd ~/Library/Application\ Support/Google/Chrome/Default/Platform\ Notifications/
ls -la
On Gnu/Linux (at least on Linux Mint), similarly you can find the log file(s) in /home/user/.config/google-chrome/Profile 1/Platform Notifications/ – jdmayfield
Now you will see files like this:
drwx------@ 7 visi staff 224 Jul 13 18:16 .
drwx------ 75 visi staff 2400 Jul 15 11:05 ..
-rw-------@ 1 visi staff 759 Jul 15 10:57 000003.log
-rw-------@ 1 visi staff 16 Jul 13 18:16 CURRENT
-rw-------@ 1 visi staff 0 Jul 13 18:16 LOCK
-rw-------@ 1 visi staff 147 Jul 13 18:16 LOG
-rw-------@ 1 visi staff 41 Jul 13 18:16 MANIFEST-000001
You can see the most recent one is 000003.log, so check it by next command:
tail -n 100 000003.log
And you will see last 100 items from this log. Then you can open chrome settings and disable that website notification.
Note that if you have several profiles in chrome, your path can be different, like this (Profile1 instead of Default):
cd ~/Library/Application\ Support/Google/Chrome/Profile\ 1/Platform\ Notifications/
If you are using MS-Windows,
then go to %LocalAppData%\Google\Chrome\User Data\Default\Platform Notifications, there is a log file of past notifications.
For Ubuntu, jump down to The final "one-liner" section at the bottom.
This is modeled after @Andrey Bezpalenko's answer, but tested to be functional also on Ubuntu 18.04.
As is the case with his answer too, however, the output is pretty stinking ugly, as it's binary output with readable ASCII character strings intermingled in with the binary. Here are the steps:
Find the latest log file (*.log) in the "Platform Notifications" directory for your Chrome installation:
find ~/.config/google-chrome | grep --extended-regexp \
"google-chrome.{0,30}Platform Notifications.*\.log$" | tail -n 1
Sample Output:
$ find ~/.config/google-chrome | grep --extended-regexp "google-chrome.{0,30}Platform Notifications.*\.log$" | tail -n 1
/home/gabriel/.config/google-chrome/Default/Platform Notifications/000003.log
We can see we found the log file here: /home/gabriel/.config/google-chrome/Default/Platform Notifications/000003.log.
View the last, let's say, 10 lines, or log entries, from this log file:
tail -n 10 "/home/gabriel/.config/google-chrome/Default/Platform Notifications/000003.log"
Sample output of just the last 3 items (tail -n 3 "/home/gabriel/.config/google-chrome/Default/Platform Notifications/000003.log"). Notice how flippin' ugly this is to try to read and interpret!
$ tail -n 3 "/home/gabriel/.config/google-chrome/Default/Platform Notifications/000003.log"

tail -n 10 "$( find ~/.config/google-chrome | grep --extended-regexp "google-chrome.{0,30}Platform Notifications.*\.log$" | tail -n 1 )"
Or even better, also print out the path to the log file:
Last updated 16 Sep. 2024.
LOG_FILE="$( find ~/.config/google-chrome | grep --extended-regexp \
"google-chrome.{0,30}Platform Notifications.*\.log$" | tail -n 1 )"; \
echo -e "LOG_FILE=\"$LOG_FILE\"\n---------\n"; \
tail -n 10 "$LOG_FILE" | strings | sed 's/sessionIndexI/&\n/g'
Can anyone make this output look less horribly ugly? I'd like to see prior notifications in a more readable format!
Update 25 May 2020:
Here's one step closer to something useful: after running the "final one-liner" above, do this to extract just the ASCII chars from the binary, and remove extraneous spaces.
strings "$LOG_FILE" | sed -E 's/[ ]{8,}/\n/g'
First, strings extracts ASCII strings from the binary file. Then, the "'s'tream 'ed'itor", sed, 'g'lobally replaces all instances of 8 or more spaces in the 's'tring with a newline char, \n, since I noticed there were dozens if not hundreds of spaces in a row sometimes, which dramatically reduced readability. The -E in sed is to allow 'E'xtended regular expression searches.
Note that the one-liner command above already stored the file path into the LOG_FILE variable, so we are just going to re-use that variable here. See echo "$LOG_FILE" if you need to see what that variable holds.
After doing the above, you'll get something like this:
$ strings temp.txt | sed -E 's/[ ]{8,}/\n/g'

As it seems not possible to get a record of the notifications directly, if I had the same problem, I would cheat by using an android phone emulator, or a phone, as the user who recommended Pushbullet. But there is not only Pushbullet, there are a lof of other apps, we could discuss the android tricks to listen and record notifications, in a separate thread.
If you are a programmer, you could maybe solve your problem though a home-made extension:
https://stackoverflow.com/questions/15949606/how-can-i-listen-to-notifications
"You can hook the webkitNotifications.createNotification function so that whenever a notification is created you run some particular code."
Touching something that was mentioned a bit above but with a twist that insure you are not missing the notification on OSX:
On the right side of the main top bar, click on the notification icon.
Click the cogwheel (lower right of the notification display)
Select Chrome to setup how notifications are displayed.
By default "Banners" are selected and they can vanish automatically. Instead, select the "Alert" type and they will stay there as long as you are not acknowledging them!
You are welcome :)
If using MS-Windows 10. You can see the history of Push Notifications. On the very bottom right corner of your PC screen on the taskbar is what looks like a speech bubble and if you hover over it you will see it is actually called "notifications". If you click that bubble it will show your unread/new emails and any push notifications you have not dismissed. I came here looking for this answer and did not find it but then managed to work this out. I am using Windows 10.
Thanks to Corey's answer above, and a lazy Saturday with too much time on my hands, I can now see a list of recent Chrome notifications in my IDE's console, where I can even click on the URLs.
The code is crappy and uses crude heuristics since I have no clue of the correct way to interpret the binary data.
But it's a ton better than nothing. Example output (excerpt):

There is a Chrome extension called NOTYFY which aggregates notifications from many sites that you are logged into (gmail, facebook, stackoverflow, twitter, etc).
NOTYFY essentially builds a running log of notifications from these sites so you can access them in one place.
So the answer is yes, you can access notification history but in a very constrained way.
NOTYFY does not aggregate all site notifications, just the ones it is programmed for and are logged in. Even those require patches as the sites change their notification APIs.
It's stored in a levelDB database in the Platform Notifications folder as other commenters have mentioned.
The DB format was documented here - https://www.giac.org/paper/gcih/20579/google-chrome-notification-analysis-in-depth/128522
If you use LevelDBDumper or similar you can easily see all the data:
LevelDBDumper.exe -d "C:\Users\User\AppData\Local\Google\Chrome\User Data\Default\Platform Notifications" -o "c:\temp" -t csv
Alternatively, use SQLiteHunter + Velociraptor as documented below: https://blog.nviso.eu/2024/09/06/hunting-chromium-notifications/ https://github.com/Velocidex/SQLiteHunter
Seems as though Pushbullet may solve your issue. They claim you can see your missed notifications using their Chrome extension.
