Stays in the background and monitors web pages for changes.
❗ Update: April 15th, 2024
We maintained PageMonitor since 2015 supporting every Chrome upgrade in that time. Regrettably Google is discontinuing SQL and, in spite of our best efforts, we are unable to deploy a version that is compatible with the new versions of Chrome.
▶️ Page monitoring going forward:
To continue monitoring pages, please install our latest Visualping.io extension to:
https://visualping.io/chrome-extension/
In this version, the Browser tab allows has the same functionality as PageMonitor and is free.
We are working on a new upgrade of Visualping's extension planned to be released this summer and it will be packed with the most up to date technology to allow you to monitor pages for free using your browser.
♻️ Migration
We apologize for any inconvenience caused by data migration issues as we worked through Google’s discontinuation of WebSQL support. Please avoid closing your browser or triggering a chrome version upgrade until you attempt to migrate.
Detailed instructions can be found in this video: https://www.youtube.com/watch?v=Yb3E-xFgir4
We apologize again for all the trouble and thank you in advance for your patience as we go through this.
Latest reviews
- (2024-11-26) Chr Pqe: Bonjour, Est-ce que la synchronisation par navigateur : - Chrome Extension Sync Pour synchroniser la liste à surveiller (pas le contenu de la page, mais uniquement synchroniser la liste de sélection) est prévue ? C'est le seul inconvénient, Merci
- (2024-04-10) 壊れたまま直す気がなくvisualpingへの誘導をするつもりのようなので、3.4.8に差し戻して使っています。
- (2023-11-05) USA MF: As of Oct 31 2023 Chrome version 119.0.6045.106 (Official Build; 64bit). The list of sites are gone. Can not restore with back up. Can not add new sites. Dead in the water. Tested on older version of chrome and all is good but latest version does not let Page Monitor work. As of 10/4/23 they updated it and now works again
- (2023-08-29) Denver Gomes: Bastante funcional e simples de usar. Permite destacar as alterações que ocorreram na página.
- (2023-07-24) Tom Gray: Simply does not do as advertised - a page was updated, and i received an alert some 15mins later, despite setting it to check for updates once every minute. Don't bother with this, it just isnt fit for purpose.
- (2023-06-28) Martin: I can't tell if it works because it somehow deleted my list of monitored pages. Three times in a row.
- (2023-06-08) Conrad Braam (zaphodikus): I triggers to indicate that a page has changed, but then it hangs, so not usable. abandoned back in 2018.
- (2023-04-21) Matt Collinge: Still working well for me in 2023. The best thing is the ability to use CSS-style selectors to narrow the check down to specific area(s) of the page.. that makes it get 5 stars from me. Works great! Improvement request; if you could add a customisable delay for the test, so that pages can render in extra data via an Ajax call that would help with sites like Quidco.
- (2023-02-22) Alan Perotti: It does nothing :(
- (2023-01-17) Libor R: Does not work at all. "Monitor this page" button does nothing.
- (2023-01-14) SHARCRASH: Tried to monitor one website, the extension didn't work.
- (2022-12-08) Joosep-Georg Järvemaa: Does not work any more :( Regardless of interval it does not check again...
- (2022-11-30) Altaf Ali: i think this extension is hacked or modified by some else because it is show some annoying links in text mode
- (2022-10-17) Anthony “High Ranking Giraffe” Steele: It's alerting every 3 hours when there's no change
- (2022-07-12) Tayza Ferreira Pereira: Simples e prático, funciona!
- (2022-06-06) David Ibañez (Mutshadar): Aunque de primeras pueden agobiarte un poco todas las opciones que te presenta. Si te tomas la molestia de indagar un poco puedes descubrir todo el potencial que te ofrece esta sencilla extension. Para mi, se ha convertido en una imprescindible.
- (2022-05-31) Pat MySecret: 2022 I would say it's as another review put it,..that it doesn't work on Dynamic webpages, and that seems to be all I wanted it for. 2016 Was hoping for something to let me know if a new ebay listing was added to a page. This didn't do it.
- (2022-04-14) Arun: Works but checks only once, check interval setting is not working
- (2022-03-16) Rokkaku Dai: A veces sale un mensaje de que dejó de funcionar
- (2022-02-21) rk ml: Does not work on Dynamic web pages. Does not show any updates even though the pages have updated. For mostly static pages, this works well.
- (2021-12-22) Kamal Jain: It was such a great extension, till visual ping messed it up.
- (2021-10-26) みうらsvx: メルカリが先月にGUIを大幅リニューアルしたのですが、それ以降メルカリだけ全く反応しなくなってしまいました。どうにかしてまたメルカリで使えるようにできませんでしょうか?
- (2021-08-17) lucia cesaro: Molto valida come estensione, solo che ogni paio di giorni mi cancella la lista delle pagine monitorate, e le devo riaggiungere. C'è qualche impostazione da cambiare? qualcuno sa darmi suggerimenti?
- (2021-07-22) 平井伸治: 使いづらい。 監視時間をバーで選択できるけど、間隔が一定ではないので合わせづらい。 要素を選択するときに選びづらい。
- (2021-06-06) Hank Y: cann't find the page
- (2021-04-24) sevenreasons: rip
- (2021-03-22) Dai Kuni: Cache corruption detected and fixed. Last snapshot discarded. Changes highlighting will be available on next update. というエラーが出て差分が表示されなくなってしまう。 設定を見てみると登録したURLリストが消えている。 登録したときに毎回Exportで設定リストを保存してるのでまたImportすればよいのだが、 なんだかなんどやっても消えてしまうようになった。 行うべき設定があればヘルプページに記載してほしい。 Cache corruption detected and fixed. Last snapshot discarded. Changes highlighting will be available on next update. Error appears and the difference is not displayed. Looking at the settings, the registered URL list disappears. Every time I register, I save the setting list with Export, so I should import it again. Somehow it disappeared no matter how much I tried. If there are any settings to be made, please describe them on the help page.
- (2021-03-03) Meshari Albarrak: I love it
- (2021-02-20) sqorpy: Its look like no one maintain the code anymore. this extension is very flaky and unreliable. it use to be great few years ago.
- (2021-01-22) Tzveta Dryanovska: Super useful and simple to use! Works great :)
- (2021-01-22) Cengiarotti Zorzi: usando lo stesso account su altri pc non si sincronizza, si deve caricare le pagine da monitorare su tutti i pc manualmente.
- (2020-11-28) Emanuele Francesco Russo: L'applicazione è ottima...ma nel tempo perde tutte le pagine che gli ho indicato da monitorare. E' la terza volta che tolgo e installo nuovamente l'estensione.
- (2020-11-22) Peter Lee: When it works, it is great. Don't try using it with more than 2 or 3 pages. Once you get past 4 pages, it will just delete everything you were tracking and you'll need to start fresh from a blank slate.
- (2020-10-25) Николай Фадеев: Супер приложение. Единственное когда случайно нажал удалить проверяемую ссылку отката назад нет. Пиши "пропало". Или есть метод?
- (2020-10-17) Alex Mendez: I love how straight forward the extension is but when clicking on the extension there is a bug where it doesnt show the websites that have changed. but the workaround is that you can have a chance to see which websites has changed. But there is another problem. when checking to see what the difference is, it "loads the difference" indefenitely. Workaround is that you have a chance to see what has changed...
- (2020-10-14) ポール: Does not work. I set the refresh interval to 5 seconds and it didn't refresh for 10 minutes.
- (2020-10-05) Logan Henry: Works good but it would be nice if it was possible to have different settings for the same page. That way you could have different sounds for different elements on the same page using the element picker.
- (2020-10-05) Padma Sandro Casini: è già la seconda volta che perde le pagine monitorate. Inaffidabile
- (2020-10-04) Старый Помидор: Слово найдено пишется в русском языке с одним Н.
- (2020-09-29) Оксана: Он работает и это прекрасно.
- (2020-09-28) Davide Spagocci: Work perfect to me in Microsoft Edge , thank you for create this add on.
- (2020-09-25) James Jackson: I love this extension! It does everything I want
- (2020-09-25) Corbin Rose: CONSTANTLY LOSES YOUR DATA. Would be nice if your settings didn't keep getting erased.
- (2020-09-13) Ghislain P.: Je reçois les alertes de changements mais lorsque je vais dessus, rien de nouveau. N'a plus l'air de fonctionner...
- (2020-07-30) Elder Bernardes Teixeira: Gostaria de sugerir que o aplicativo funcione em todos as sessões do chrome logadas, usando os mesmos sites monitorados (sugestão: talvez criar uma pasta de favoritos no chrome e monitorar essas páginas, perderíamos as opções de filtrar elementos da página para monitorar, mas acredito que seria mais simples de implementar)
- (2020-07-30) Jan Goyvaerts: The list of sites was cleared yet again. I'm using this extension for years now, but this is it. Sad.
- (2020-07-16) Yasin ERBAKILI: Son zamanlarda hatalı uyarı verse de yıllardır kullandığım ücretsiz bir eklenti. Tavsiye edilir.
- (2020-07-12) Brian Leitner: Used to work better. Now most pages get stuck at "Diffing in progress."
- (2020-04-15) Sharif I.: Requires a website to monitor changes!! Not directly in chrome.
- (2020-03-16) Abdulrahman: It stuck in "Diffing in progress" most of the time. Any idea why this happens? The same happens in different PCs.
