## Self-Hosted, Open Source, Change Monitoring of Web Pages
|
|
|
|
_Know when web pages change! Stay ontop of new information!_
|
|
|
|
Live your data-life *pro-actively* instead of *re-actively*, do not rely on manipulative social media for consuming important information.
|
|
|
|
Open source web page monitoring, notification and change detection.

|
#### Example use cases
|
|
|
|
- Products and services have a change in pricing
|
|
- Governmental department updates (changes are often only on their websites)
|
|
- New software releases, security advisories when you're not on their mailing list.
|
|
- Festivals with changes
|
|
- Realestate listing changes
|
|
- COVID related news from government websites
|
|
- University/organisation news from their website
|
|
- Detect and monitor changes in JSON API responses
|
|
- API monitoring and alerting
|
|
- Trigger API calls via notifications when text appears on a website
|
|
- Glue together APIs using the JSON filter and JSON notifications
|
|
- Create RSS feeds based on changes in web content
|
|
- You have a very sensitive list of URLs to watch and you do _not_ want to use the paid alternatives. (Remember, _you_ are the product)

_Need an actual Chrome runner with Javascript support? We support fetching via WebDriver!</a>_

|
docker-compose pull && docker-compose up -d

|
|
|
|
### Notifications
|
|
|
|
ChangeDetection.io supports a massive amount of notifications (including email, office365, custom APIs, etc) when a web-page has a change detected thanks to the <a href="https://github.com/caronc/apprise">apprise</a> library.
|
|
Simply set one or more notification URL's in the _[edit]_ tab of that watch.
|
|
|
|
Just some examples
|
|
|
|
discord://webhook_id/webhook_token
|
|
flock://app_token/g:channel_id
|
|
gitter://token/room
|
|
gchat://workspace/key/token
|
|
msteams://TokenA/TokenB/TokenC/
|
|
o365://TenantID:AccountEmail/ClientID/ClientSecret/TargetEmail
|
|
rocket://user:password@hostname/#Channel
|
|
mailto://user:pass@example.com?to=receivingAddress@example.com
|
|
json://someserver.com/custom-api
|
|
syslog://
|
|
|
|
<a href="https://github.com/caronc/apprise#popular-notification-services">And everything else in this list!</a>
|
|
|
|
<img src="https://raw.githubusercontent.com/dgtlmoon/changedetection.io/master/screenshot-notifications.png" style="max-width:100%;" alt="Self-hosted web page change monitoring notifications" title="Self-hosted web page change monitoring notifications" />
|
|
|
|
Now you can also customise your notification content!
|
|
|
|
### JSON API Monitoring
|
|
|
|
Detect changes and monitor data in JSON API's by using the built-in JSONPath selectors as a filter / selector.
|
|
|
|
|
|
|
|
This will re-parse the JSON and apply formatting to the text, making it super easy to monitor and detect changes in JSON API results
|
|
|
|
|
|
|
|
#### Parse JSON embedded in HTML!
|
|
|
|
When you enable a `json:` filter, you can even automatically extract and parse embedded JSON inside a HTML page! Amazingly handy for sites that build content based on JSON, such as many e-commerce websites.
|
|
|
|
```
|
|
<html>
|
|
...
|
|
<script type="application/ld+json">
|
|
{"@context":"http://schema.org","@type":"Product","name":"Nan Optipro Stage 1 Baby Formula 800g","price": 23.50 }
|
|
</script>
|
|
```
|
|
|
|
`json:$.price` would give `23.50`, or you can extract the whole structure
|
|
|
|
