I played with the examples and I am extremely impressed. I couldn't tell at all that I was being recorded; I figured the examples would just be videos of people interacting with those pages. The speed-up feature is very neat too.

Very good work. I am actually a little surprised something like this is open source.

Hi, hackers, the author here.

Since I've seen some people are talking about the open source idea and comparing rrweb to some commercial products, I'd like to share a blog post about the vision of rrweb.

Also, you will know about how rrweb works in this post.

This looks awesome! Does anyone have recommendations for a tool that can do this but also let me save the video? Preferably, below 100MB per 5sec recording...

I mean, come on, how smooth is this library?

Amazing, I planned to work on something similar in 2019 for our SaaS, you just saved me few days / weeks of work :) Thanks

Looks really cool, but I find myself thinking about the privacy implications of using this, especially by default. Even if the user gives consent, it still implies recording every single mouse movement and keystroke on the site.

Has this been normalised? Is this the new default?

Food for thought.

Thanks for open sourcing your work. I had already built something similar to this and other commercial products, but in jQuery.

Really interested to see how this compares.

I did see the IE11 issue. Are there any thoughts on what can be implemented for a fallback?
