What HN said

What people liked

  • Set-and-forget reliability when self-hosted via Docker

    From 2 comments
    • I've been running this software locally as a docker container on my laptop since about February 2021, obviously with a few updates/restarts, but generally it is set and forget

    • Nice and easy to self-host with Docker, thanks. Might save me more than a few bookmarks that I check every couple weeks manually. Small feature wish: optionally fetch and display…

  • Replaces paid services like Visualping

    From 1 comment
    • I used this to replace Visualping.io. The only features it lacks compared to VisualPing is a GUI for selecting page elements to monitor and fully rendered diff results. It either…

Objections

  • Hard to tell whether page structure changes are meaningful

    From 1 comment
    • I think you're right that the services themselves break, but more often than not, the failure mode is that what page you're monitoring changes its structure, and then every…

  • Cannot extract snippets or regex matches within lines

    From 1 comment
    • Nice little project. I played around with it for a bit, but couldn't figure out how to extract snippets (e.g. a list of headlines, like from the hackernews home page). It seems…

  • Does not handle dynamically loaded XHR content well

    From 2 comments
    • I tried this project recently, but it didn’t seem to handle pages that load content dynamically via XHR. At least the couple pages I tried at the time.

    • Indeed I had it setup using a separate selenium chrome container. Still had the same issue

Requests

  • Browser extension for adding URLs

    From 2 comments
    • Nice! Does it have an API for adding URLs to monitor? Would be nice to have a browser extension to do that easily.
      eterps on HN
    • This would fit well as a browser extension - generate your own feeds with or without RSS. Coupled with a simple topic classifier with user defined topics it would bring some…

  • API for adding URLs and retrieving snapshots

    From 1 comment
    • Yeah, coming in the next week or so actually, or feel free to open a PR! also adding an API to retrieve snapshots (text/JSON) too

    • Visualping.io works pretty well as a SaaS. They have an okay free tier (65 checks per month). https://visualping.io/pricing I just wish their pricing model was less check-based.…

  • urlwatch

    From 2 comments
    • The linked software is for self-hosting. In my experience self-hosting is the safest bet. When self-hosting it's of course best to use software packages that automatically get…

  • Zyte

    From 1 comment
    • > Is there a change-detection service like this, being provided with stable SLAs by one of the cloud IaaS providers? You're looking for Zyte (formerly ScrapingHub).
