导读
Huginn 是一个开源、可自托管的自动化平台：你可以在自己的服务器上创建各种 agent，用来监控网页、RSS、社交媒体等信息源，并在条件满足时发送通知或执行动作，常被视为可自托管的 IFTTT/Zapier 替代品。它尤其适合做定时网页抓取和轻量过滤，但不擅长复杂逻辑和系统间的双向同步。
为什么经久不衰：它免费、自托管、数据可控，作者和长期用户至今仍在日常使用，经过十多年社区检验，今天仍是搭建个人自动化流程的实用工具。

原作者说明 Huginn 的定位：擅长定时抓取与轻量过滤，不擅长复杂逻辑和双向同步。
一觉醒来发现自己发起的项目上了 HN 首页，挺有意思。我现在已不太参与项目的日常维护。这个项目不再年轻，借机聊几句：Huginn 最擅长做带轻量过滤的定时网页抓取，我就是这么用的；虽然可以在里面写自定义代码，但它不擅长实现复杂逻辑，更不适合系统之间的双向同步——这恰是很多人希望它做的，但它并非为此设计。如果 IFTTT 或 Zapier 满足需求，那很好，不必自己运行和监控服务；我选择在自己的硬件上跑 Huginn，很大程度上是为了能放心把网站的 cookie 和密码交给它。我目前用它实时监控 Twitter 上某些关键词的异常峰值，触发推送或摘要邮件；也监控罕见词和很少发推的用户；还抓取一些很少更新的博客。

It's fun to wake up to find a project that I started on the top of HN! These days, I'm no longer very involved with the day-to-day of the project. Now that it's no longer a young project, here are some musings about Huginn and responses to people's comments in this thread, in no particular order. I've found that Huginn excels as a scheduled web scraper with lightweight filtering. That's what I use it for. On the other hand, while you can write custom code in it, Huginn is pretty poor at implementing any sort of complex logic, and is even worse at bidirectional syncing between systems, which is something people often want it to do, but for which it wasn't designed. If IFTTT or Zapier meet your needs, awesome! No need to run and monitor your own service. I personally choose to run Huginn on my own hardware in large part so that I'm comfortable giving it website cookies and passwords. Some examples of what I use Huginn for these days: - Watching Twitter in realtime for high standard deviation spikes in certain keywords, such as "san francisco emergency" or "san francisco tsunami warning", which then sends me a push notification, or "huginn open source", that goes to a digest email (and I imagine will trigger because of this thread). - Watching Twitter for rare terms and sending me a digest of all tweets that match them. Also sending me all tweets from a few Twitter users who post rarely, but that I don't want to miss. - Scraping a number of rarely updated blogs that don't have email newsletters and emailing me when they change. Some use RSS, most are just simple HTML scraping. - Pulling deals from the frontpage and forums of slickdeals and craigslist and filtering them for certain keywords. - Sending an early morning email if it's going to rain today. - Watching ebay for some rare items. - Sending my wife and me an email on Saturday morning with local yardsales from craigslist. - Watching the HN and producthunt front pages for certain keywords. Basically, anytime I find myself checking a website more then a few times, I spend 20min making a Huginn Agent to do it for me. I think one reason Huginn has worked well for me is that I don't try to make it do too much. I use it for scraping data and gentle filtering, and that's about it. It's been super helpful for alerting me to interesting content for The Orbital Index, my current project, a weekly space-industry newsletter.

相比 Zapier，Huginn 的卖点是自托管、免费、可定制、隐私可控且可靠。
它不只是替代品：自托管；无限量且免费，而 Zapier 要 699 美元/月；可自己写 agent/集成；可用 shell 脚本或 JavaScript 处理数据；过滤更强；支持 Liquid 模板；完全私密。我用 Huginn 省下数千美元。它非常强大，而且我不放心把数据交给 Zapier，也不喜欢它对我所做的事的可见性，因为涉及商业影响。可以跑在 AWS 云上或家里的旧机器上，非常可靠。

Not just an alternative though. - Self-hosted - Unlimited and FREE vs $699 / month - Create your own agents / integrations - Process data through shell scripts or JavaScript - Better filtering - Liquid templating - Completely private I save thousands of dollars by using Huginn. It's incredibly powerful and quite frankly I don't trust Zapier with my data and visibility of what I'm doing because there are commercial implications. Run it in the cloud on AWS or on an old box at home. It's very reliable.
实际用途包括 RSS 过滤、转发到 Telegram、页面变更通知；灵活但缺少循环控制。
我在家用服务器上跑 Huginn 有一段时间了，主要用来过滤 RSS 源，再用过滤后的条目生成新源；另一个用途是读取网络漫画的 RSS（或抓取页面），把漫画发到私人 Telegram 频道。我还用过一个 agent 抓取房源页面，有变化就通知我。我试过 node-red 等替代品，但在这些场景下都不太合用；Huginn 非常灵活，它的工作流心智模型（至少对我）很说得通。可惜越来越多网站要求你通过它们的 App/站点访问，比如从 Instagram 账号取内容就变难了。我还没搞明白的一点是循环：比如抓一个页面，想输出某个 img 标签的 src，同时检查页面上是否存在“下一页”按钮，先输出找到的 src，再用新的输入重新调用 agent，抓下一页，直到找不到按钮为止——这类自动化工具似乎都缺这个。

I have been running huginn on my home server for a while. I've mainly used it to filter RSS feeds and then generate new feeds with the filtered items. Another use-case for me is ingesting webcomic RSS feeds (or scrape a page) and post the comics to a private Telegram channel. Once I also had an agent scraping a page and notifying me if something changed (realestate listing). I have tried a couple alternatives, e.g. node-red but none really worked the way I wanted them to for these cases. huginn is incredibly flexible and (at least for me) the mental model of it's workflow makes a lot of sense. Sadly more and more pages want you to go through their app/site and make it a bit difficult to work with, e.g. getting content from an instagram account. One thing I have not figured out about huginn and which all of these automation tools seem to lack are loops. E.g I have page an agent scrapes, from which I want to output the src of an image tag but I also want to check if a certain condition on the page matches (e.g. a "next page" button exists) and then firstly output the found src but then also re-invoke the agent with a new input element. So it would scrape the next page and so on until it does not find the button anymore.
功能强大但学习曲线陡，很多通知类用例缺少明确行动场景，实际价值有限。
几年前发现它，被类似 JARVIS 的潜力吸引，深入研究。学习曲线很陡，但一旦弄懂几次，它确实很强大，能做很多事。我的问题是：我能做的那些事似乎并不特别有用。知道天气有用，但我自己也能大概知道；知道股票趋势上下，只有我要采取行动时才有用。现在装了太阳能，能看到更多用例，但大多还是出于好奇，而不是知道何时该行动。

I found this a few years ago and was super intrigued JARVIS-like potential and dove into it. There's a STEEP learning curve but once you get it figured out a couple times, it's really powerful and you can do a lot. My problem is that the things I could do.. didn't particularly seem useful. Sure, knowing the weather is useful but I can get a pretty good idea on my own or checking the times I need to know more. Knowing about trends up/down in my stock is only useful if I'm going to act. Now that I have solar, I can see some more use cases but most are also around curiosity vs knowing when to take action. I may come to a different conclusion if I build an armored combat suit. Or for a more realistic and fun story, check out Daniel Suarez's Daemon. It's great.
