これは何？

changedetection.io watches web pages for content changes and sends notifications when something differs from the last check. It is aimed at tracking prices, restocks, news updates, documents, and JSON API responses without manually reloading pages. Notifications are delivered through the apprise library, which covers services such as Discord, Email, Slack, Telegram, and custom webhooks.

Watches can target specific parts of a page using CSS selectors, XPath, regular expressions, JSONPath, or jq, and can fetch either with a fast HTTP fetcher or a Chrome-based browser for JavaScript-heavy sites. Browser steps can log in, click buttons, or fill forms before checking. Changes can be reviewed word by word, line by line, or character by character, and PDF files can be monitored by text content, size, and checksum.

The project can run through Docker, docker compose, or pip, and exposes a REST API with an OpenAPI specification. Optional LLM features can summarise changes or filter alerts using providers such as OpenAI, Gemini, or a local Ollama instance.
