Kibitzr is a Python-based tool that automates the monitoring of web pages for changes. It continuously checks specified URLs, detects modifications in content (or CSS selectors), and notifies you via email, Slack, or other channels. With simple YAML configuration, you can set up monitors for price drops, job postings, news updates, or any dynamic content. Running as a daemon or via cron, it's ideal for users who want a self-hosted, privacy-friendly alternative to cloud monitoring services. Its lightweight nature makes it suitable for both personal use and small teams.
