  • The Risks of User Impersonation
    2 projects | dev.to | 24 Jan 2025
    The next rung up are User recordings. For users that are having issues, we have concrete recorded data for their flow. The flows would include anything relevant to the application, how they used it, what actions they took. All so we can actually see what happened in context for when there is a problem. No one wants to spend any time looking at recordings if they don't have to. It is also very difficult to identify the root cause of problems by reviewing a recording, but having them is indispensable to your support engineers when they need them, when a user has reported a issue. Solutions include PostHog, FullStory, Sentry. If you don't have these recordings, then the next best alternative (which is very far away) is getting a live screencast from the user. These are less useful, and more expensive to obtain. Worst of all, they can and have been used to breach sensitive systems.

    Posthog. Posthog has a lot of sub products but I use it mainly for analytics and session replays. I have to say Posthog is an impressive product. Everything from dev experience to dashboards is just awesome. Great to see GA finally got some real competition. I'm looking forward to try all the other products from them.

  • 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 — the self-hosted session replay tool that helps developers troubleshoot web apps faster — 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).

    You should have tried Quickwit :)

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