    It would be a shame not to mention PostHog as the telemetry provider we are using, since it turned out to be extremely useful. Because it is hard to find people who will talk with you about your product, gathering statistics gave us a much greater insight into our users.

    Hi HN, PostHog employee here. I'm working on our Web Analytics product, which is currently in beta. It's fun to see us mentioned here :)

    I should mention that we have a ton of SDKs (see https://posthog.com/docs/libraries) for back end frameworks and languages, so if you wanted to use PostHog without any client-side JS you could send pageviews and other events manually, but for the vast majority of people it makes more sense to use our JS snippet.

    Hijacking this comment to share the roadmap for web analytics https://github.com/PostHog/posthog/issues/18547. It's very much in the launch-early-and-be-embarassed phase, but I would love to hear any feedback or suggestions that people have, particularly if you're already a PostHog user.

    Don't insert the logs/events/analytics into your Application DB. Usually, you send those to specialist datastores (OLAP etc) that process such high volume of data. You can use something like clickhouse [0] for example or use 3rd party SAAS solutions like posthog [1] etc that are built on top of clickhouse

  • Ask HN: What would you use to build a mostly CRUD back end today?
    5 projects | news.ycombinator.com | 16 Sep 2023
    I may use Flask-Admin initially to offload the "CRUD" operations to have an initial prototype fast but then drop it ASAP because I don't want to write a "flask-admin application" to fight against later on. If the application is mainly "CRUD", then Flask-Admin is suitable.

    Now...

  • Show HN: Tabbing through bugs? One replay to catch them all
    1 project | news.ycombinator.com | 16 Feb 2024
    Hey HN,

    For anyone who uses session replay tools to debug, monitor, or analyze user journeys, this feature might come in handy. OpenReplay β€” the self-hosted session replay tool that helps developers troubleshoot web apps faster β€” now supports tabbed browsing.

    *Here's how:*

    1. Capture and replay user sessions that span across multiple browser tabs, all within a single recording.

    2. OpenReplay's tracker communicates across browser tabs, ensuring accurate tracking of each tab, even when duplicated or opened with `window.open` without `_blank`.

    3. With "co-browsing", you can watch and support users in real-time and see how they navigate across multiple tabs of your app.

    *Why it’s important?*

    1. This feature is convenient for developers as it allows them to easily identify bugs by reviewing a complete session in one replay, rather than having to reference multiple recordings.

    2. It provides a deeper understanding of the user journey and interactions across multiple tabs in your web app, helping in the comprehension of complex user behaviors and paths.

    3. It provides accurate feedback on user tab actions such as opening, switching, and closing tabs, assisting in UX/UI improvements.

    Interested? For more details, you can check out the GitHub repo at https://github.com/openreplay/openreplay.

    You could maybe get in a scenario where a company rather sneakily changes their license without proper announcement to make usage non-open and billable, but that's pretty rare and bad behavior and that underhandedness may bite them back if it goes to court (I am not a lawyer). That said, it can happen. As an example, see this discussion I opened where the project switched licenses and the maintainers thought it was enough to only really announce this within a 1 hour YouTube video (Rather than their blog or update notes).

    OpenReplay would not be typically be considered open source. (Which I have raised with them and have since been blocked from their repos).

    How does it compare to OpenReplay ?

    You should have tried Quickwit :)

    Anyway, sounds like a great project, best of luck!

    I would disagree with OpenReplay being open source, as I raised with them back in July (I've also since been blocked from their GitHub org for opening that discussion).
