dgtlmoon/changedetection.io

changedetection.io is a self-hosted application that monitors web pages for changes and sends alerts to channels including Discord, Email, Slack, Telegram, and Webhook. It supports visual element selection, recorded browser steps, and optional AI-powered change summaries.

Project overview

It solves the recurring problem of knowing when pages change—prices, restocks, content, or defacement—without manual re-checking, and offers full self-hosted change monitoring for free with an optional paid SaaS.

Project type: AI Search
Deployment: Refer to project documentation
License: Apache-2.0

Best for

General users and operations teams who want to know when web pages change and can run the self-hosted application (no coding required, web GUI and API available).
Users who want free, self-hosted monitoring that runs without a GPU, including on Raspberry Pi and ARM devices.

Key capabilities

Monitors web pages for changes and sends alerts via Discord, Email, Slack, Telegram, Webhook and more using the apprise library.
Connect any LLM (OpenAI, Gemini, Anthropic, Ollama etc.) to get plain-language change summaries and filter diffs by plain-English intent.
Record interactive browser steps (logins, clicks) before detection and visually target page elements; requires Playwright to be enabled.

Limitations and risks

The Visual Selector requires a Playwright content fetcher connection.
Enabling AI/LLM features transmits monitored content and diffs to a third-party AI provider outside the installation; a fully local option exists via Ollama, vLLM, or LM Studio.
The user is solely responsible for compliance with the monitored sites' terms of service and robots.txt.

Getting started

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