changedetection.io

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
• Detect and monitor changes in JSON API responses
• API monitoring and alerting

Need an actual Chrome runner with Javascript support? see the experimental Javascript/Chrome support changedetection.io branch!

Get monitoring now! super simple, one command! Run the python code on your own machine by cloning this repository, or with docker and/or docker-compose

With one docker-compose command

docker-compose up -d

or

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 :)

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 apprise 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://

And everything else in this list!

JSON API Monitoring

Detect changes and monitor data in JSON API's by using the built-in JSONPath selectors as a filter.

This will re-parse the JSON and apply indent to the text, making it super easy to monitor and detect changes in JSON API results

Proxy

A proxy for ChangeDetection.io can be configured by setting environment the HTTP_PROXY, HTTPS_PROXY variables, examples are also in the docker-compose.yml

NO_PROXY exclude list can be specified by following "localhost,192.168.0.0/24"

as docker run with -e

docker run -d --restart always -e HTTPS_PROXY="socks5h://10.10.1.10:1080" -p "127.0.0.1:5000:5000" -v datastore-volume:/datastore --name changedetection.io dgtlmoon/changedetection.io

With docker-compose, see the Proxy support example in docker-compose.yml.

For more information see https://docs.python-requests.org/en/master/user/advanced/#proxies

This proxy support also extends to the notifications https://github.com/caronc/apprise/issues/387#issuecomment-841718867
