## Self-hosted change monitoring of web pages.

_Know when web pages change! Stay ontop of new 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 
- Festivals with changes
- Realestate listing changes


**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
```

### Future plans

- Greater configuration of check interval times, page request headers.
- ~~General options for timeout, default headers~~
- On change detection, callout to another API (handy for notices/issue trackers)
- ~~Explore the differences that were detected~~ 
- Add more options to explore versions of differences
- Use a graphic/rendered page difference instead of text (see the experimental `selenium-screenshot-diff` branch)
