X 上不少搞监控降价、抢票和抓羊毛的佬都在偷着用这个工具。

GitHub 上狂拽 32.6k Star 的神器 http://changedetection.io，说白了就是“全网网页盯盘外挂”。不管是商品降价、库存补货、网页偷偷打补丁、还是某大佬微博/推文被删，只要网页变动哪怕一个字，它都能第一时间给你发推送！最牛的是现在直接接入了 AI（支持 GPT-4o-mini、Ollama 本地大模型），不再是死板地报“网页变了”，而是能帮你直接归纳出“降了 50 块”或者“新增了某某功能”。写个自然语言规则就能过滤所有噪音，白嫖党和自动化党狂喜。

核心绝活：

可视化画框监控： 鼠标点哪监视哪，自动跳过广告和无用页脚。

AI 智能去噪摘要： 接入免费模型，只告诉你最关心的变动细节。

无缝对接通知通道： 微信、钉钉、Telegram、Discord、邮件全搞定。

自动模拟点击操作： 自动登录、自动点同意 Cookie、自动翻页监控。

支持本地私有化部署： Docker 一键拉起，数据完全控在自己手里。
