展示HN：Canary – 监控任何网址的变化，获取人工智能驱动的智能分析
Canary 监控任何网址，并在发生变化时提醒您——包括竞争对手定价、API 端点、文档、招聘信息板和状态页面。变化根据信号强度评分，分值范围为 1 到 10，并由人工智能进行总结。
该项目由我独立开发，登陆页面今天已上线。自动化爬虫在 GitHub Actions 上运行，每小时将实际检测到的变化发布到 Bluesky，每天发布到 X。

欢迎就架构方面的问题进行咨询——我特别自豪于 URL 去重的方法，使得一次爬取可以服务多个订阅者。

Canary watches any URL and alerts you when something changes — competitor pricing, API endpoints, docs, job boards, status pages. Changes are scored 1-10 by signal strength and summarised by AI.
Built solo. Landing page live today. Automated crawler running on GitHub Actions posting real detected changes to Bluesky hourly and X daily.

Happy to answer questions about the architecture — particularly proud of the URL deduplication approach where one crawl serves multiple subscribers.
