Run changedetection.io, the open-source website change monitor, from a pre-configured AMI in your own AWS account. Watch pages for content changes, price drops and restocks, and get alerts wherever your team works.
changedetection.io is an open-source tool, licensed under Apache 2.0, that checks the web pages you choose on a schedule and alerts you when their content changes. Teams use it for competitor pages, price drops, restocks, changelogs and public notices.
Watch part of a page with CSS, XPath, JSONPath or jq.
Track product prices and back-in-stock changes.
Email, Slack, Discord, Telegram, Teams and webhooks, via Apprise.
Compare each change by word, line or character.
Timezone-aware check times, limited to set days and hours.
Manage watches from your own scripts, with an OpenAPI spec.
Running changedetection.io properly needs a container runtime, a reverse proxy and SSL. The AMI arrives with them set up.
Subscribe on AWS Marketplace and launch the CloudFormation stack with your domain and an admin password.
After 5-10 minutes, create a DNS record with the PublicIp from the stack outputs.
Open the DashboardUrl and enter the admin password. There is no username.
Paste a page address, click Watch, and add where alerts should go under Settings.

changedetection.io uses a password-only login. Enter the AdminPassword you set when creating the CloudFormation stack.
Through the Apprise library: email, Slack, Discord, Telegram, Microsoft Teams, webhooks and many more. Set them up under Settings or per watch.
Yes, automatically when your domain is hosted on Route 53. Otherwise, run the certificate script on the server as the developer guide shows.
Export your watches, remove the old stack and launch the new version from AWS Marketplace.
