Image from store PageProbe - Automatic Page Monitor

Description from store Why PageProbe? We believe that people want to save both time and money. We believe there are several things people want to follow on regular basis such as: - the current price of an expensive item (such as a television) that you would like to purchase so that you can find the lowest price and the best discount to save money - the current price of a company X stock in the stock market to find out when it is time to buy or sell in order to optimize your profits - the current price of an item in an online auction in order to bid at the last minute "just enough" - the number of followers you have in your social media accounts - the number of likes your social media post has received - the status of your web application or related software builds - the latest new post on forum Y - the latest top article with a specific Twitter search We believe that people are evaluating the things they monitor based on certain conditions and when those conditions are met, they will take action. For example, the price of the television that you want will drop below certain price. We believe that when this kind of tracking of many things happens manually every day, it is a huge waste of time and you can easily miss good discounts, buying or selling opportunities and as a result can also lose money. Therefore most of content monitoring should be easily automated so that an application will monitor the things you have defined, evaluates the results based on the conditions you have defined and then notifies you when those conditions are met so that you can take action. What is PageProbe? PageProbe WebExtension can monitor any web pages you can access on the Internet or in your company intranet. By simply right-clicking the content you see on a page, you can quickly create a tracker with optional conditions and actions and then view the status of those trackers in a simple monitoring view. By clicking the extension icon you can see a nice overview of all your trackers and the data retrieved. Trackers can be easily organized into groups. Feature highlights: - Unlimited number of trackers that can monitor any accessible page on the Internet or intranet - Fully local solution - does not require an account - Trackers can be organized into a tree based hierarchy of groups - Converters allow you to easily transform strings to numbers and perform simple arithmetic on them - Advanced conditions for trackers: contains text, doesn't contain text, contains all words, doesn't contain words, contains any words, contains any words that start with, matches regexp, is, is not, begins with text, ends with text, smaller than, smaller than or equal, greater than, greater than or equal, is going up, is going down, has changed - Boolean logic support (combine multiple conditions) - Case sensitive and case-insensitive matching - Advanced actions: show desktop notification, play audio (local or URL), set color/CSS for monitor column/row, HTTP POST, IFTTT, data history logging, event log entry - Data history logging will allow you to see with a simple chart how the value of some item has changed over time - Export tracker table as Excel - cron / crontab style advanced scheduling also supported! - Live Content Scan Mode which allows monitoring changing page values in real-time! - Discord support (post tracker results directly to a Discord channel) - Slack support (post tracker results directly to a Slack channel) - Telegram support - XPath and CSS selector support

(2025-04-06) Alon Bilu: Used to be 5* extension but unfortunately it was recently removed by Google since it's incompatible with Chrome's recent guidelines :( Hope the developer will update the extension asap
(2025-02-08) jmghjmv: I have the Parameters menu on screen for the page I'm trying to Track with PageProbe, and when i click Save I am getting a dialogue box that's telling me "URL must use either http or https protocol!" BUT the page is using https. How do I work around this dialogue box? I can't get my web page to Save - i click OK on that dialogue box but it just keeps coming back. TIP: If you install this extension and return to the tab / website you want Track Content on (by right clicking on it and scrolling down the menu) nothing will happen or work unless you REFRESH / RELOAD the page, to have the Track Content work for you now. Then you get to Set your parameters and Save.
(2024-11-26) Chr Pqe: Hello, Some bugs there and here, but the most important that makes this extension not actually as good as some well known competitors is the lack of list synchronization between computers : Chrome Extension Sync (to sync at least the list of urls and their configuration / but of course not the websites contents) Indeed, if I install the extension on many computers, I will inevitably lost the lists, Thank you

(2024-08-13) Bart Coppens: Have just set up. Worried about the chrome best practices notification however. Why is this message showing? More stars if this message wasn't worrying me.
(2024-07-29) Dzid: Only checks for text. That is not useful for me to find new date availability in a calendar date picker
(2024-06-24) Eolis Daybreak: Amazing tool with tons of customization options, does what you tell it to do. UI and UX could, however, be improved here and there. For example, tracker settings would be better displayed as a context menu instead of just a row of icons. Notifications and sound alerts need to be configured for each tracker separately using actions, it's not possible to edit this on a group level or globally. Templates aren't very intuitive, it's not really clear what settings are contained in a template and it currently just "creates" a template out of every tracker. It would be nice if there was a way to store a template with actions, conditions, etc. and being able to edit it so when it's updated, it updates all trackers using that template. Currently, if I need to change an action I have to manually edit each tracker one by one which kind of defeats the purpose of this tool (saving time) 😅 Regardless, this is a great extension, hope to see it getting updates and improvements. Love the Discord integration especially! Would also love to see an iOS/Android app so it's not required to have a PC/laptop on at all times in order to keep monitoring 😬
(2024-03-01) Oscar Chen: good as heck
(2024-02-10) Rob Penfold: Very useful especially given that it is free. Can take a little while to work out how to use it properly though, so some suggestions for any that want to try it out: 1. Before you create any trackers, create some Groups (ie folders) by clicking on the + icon. If you don't do this you will have base level trackers and it is not all that clear how to access / edit these 2. A lot of functionality is revealed by right clicking on a Group (e.g. create sub group, view / edit those mysterious baseline trackers as above) 3. Add a tracker by right clicking on a web page (or some highlighted content) > Track Content 4. Many options when you Track Content. For example you can Add Condition such that only get alerted when the page changes more than 5% for example (useful for those pages which have tiny automatic changes like the date etc). In the Add Action section, I find enabling the Show Difference option useful as then you can see what has changed Apart from those little quirks (perhaps the instructions that go with the extension could be updated?), it is pretty straightforward to use and very handy (plus free!)
(2023-08-11) Josh Nathan: I love it. I've used several (free) standalone tools to monitor webpage changes, and none of them worked consistently or notifications never came through. PageProbe seems to be working exactly as designed. It's got so many configuration options, you can really fine-tune your trackers and notifications. Thanks again for this awesome extension.

(2022-04-28) Lobo Tomy: Tried some other (much more popular page monitor extentions) but this one does the job properly. Tested it on a page to see if it'd find an image and worked like a charm. Thanks a lot!

(2022-04-25) Blog Blogger: Overall, it's OK.But there are many essential "little" things that ruin the whole experience with the extension. For instance --(1) you cannot adjust the width of the columns. (I always have to scroll the horizontal bar left to right and vice versa) --(2) It doesn't remember the sorting order you selected (for instance I want to see the most recent change always on the top, but it doesn't stick) --(3) The templates could have been independently defined (with its own name each one) and not searching among dozens of entries to find which one resemble what you want to do. --(4) Multiple selection of entries to manage them more easily --(5) Less or user controllable pop-ups. Also I have trouble with the extension not remembering the values before the last one, so the chart (for a price etc.) usually fails.

(2021-10-26) Огурчик Игривый: Just a great extension for monitoring any character content on web pages. Many thanks! But It is unclear why there is such a small limit on the number of entries in the log. 200 entries is very little. I'd love to tweak this or increase it to at least 1000 or 1 million

(2021-10-01) Saibor Nama: I like the extension. It works very well, but I hope if you can make it check every 5s and every 1s. Also the notification doesn't make any sound so I don't notice it.

(2021-06-19) Carmel C: 1YR UPDATE: Been using this for a year & wow! I have saved alot of money on monitoring website deals, price changes that come up based on my custom schedule. Much better than the alternative of signing up for website deal alerts where I have to give out my email address to get spam. ORIG REVIEW: Great website monitor tool, much better than Distill in many ways. Free for any usage, with no limits, can customize your selections with boolean & all kinds of neat ways. Where it lacks in the learning curve it makes up for in its flexibility and unlimited usage for local client side monitoring. If you want to keeep your info private, with no cloud access this is great and even better does not data mine your info like other extensions. I recommend it and hope it stays free.

(2021-06-08) nave3d: I love that this extension is free. There's some things that I liked about Distill that this app doesn't seem to have (or maybe it's just too advanced for me so I can't figure it out) Getting notifications through discord is a HUGE plus. Figuring out how to do it was a little hard as I've never set up webhooks or anything before but Google was a great help :)

(2021-05-27) Artemis Livingstone: This tracker is amazing, however I wished it had an option to send a notification when the request returned 200, as I would like to track the existence of an element on a page

(2021-04-23) Wynand Meyering: A brilliant piece of programming. I was writing something similar to monitor stock market shares and cryptocurrency websites and struggled, so I checked the web for a solution. This was it.
