## Self-hosted 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.

#### Example use cases

Know when ...

- Government department updates (changes are often only on their websites)
- Local government news (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


**Get monitoring now! super simple, one command!**

```bash
docker run -d --restart always -p "127.0.0.1:5000:5000" -v datastore-volume:/datastore --name changedetection.io dgtlmoon/changedetection.io
```  

Now visit http://127.0.0.1:5000 , You should now be able to access the UI.

#### Updating to latest version

Highly recommended :)

```bash
docker pull dgtlmoon/changedetection.io
docker kill $(docker ps -a|grep changedetection.io|awk '{print $1}')
docker rm $(docker ps -a|grep changedetection.io|awk '{print $1}')
docker run -d --restart always -p "127.0.0.1:5000:5000" -v datastore-volume:/datastore --name changedetection.io dgtlmoon/changedetection.io
```

### 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">And everything else in this list!</a>
