ChangeDetection IO

changedetection.io lets you watch web pages and APIs for changes, then alert you when something updates. Point it at a product page, a government notice, a PDF, or a JSON endpoint; choose how often to check; and use selectors and filters (XPath/CSS/JSONPath/jq, regex, ignore/extract rules) to focus on the exact content you care about. When a change is detected you can review diffs down to word/line/character level, trigger conditional notifications (keywords, thresholds like price bounds), and send alerts through a wide range of channels via Apprise (email, Discord, Slack, Telegram, webhooks, and many more). As an Eyevinn Open Source Cloud managed service, you get changedetection.io provisioned and ready to use without running containers or managing storage yourself. You can start adding watches immediately through the UI or the full REST API, scale your monitoring without babysitting infrastructure, and rely on OSC to handle the operational overhead so you can focus on building the workflows and alerts your team needs.
