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

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!
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
