rrweb

Two open source alternatives: https://github.com/oct16/TimeCat and https://github.com/rrweb-io/rrweb we are working - at Telecom Paris - on synchronizing audio recording as well for pedagogical reasons (for example making programming tutorials) here https://github.com/Telecom-Paris/generic-rrweb-recorder . You can also try our "ace editor" specific recorder to make c programming and python programming tutorials https://github.com/France-ioi/codecast look at the recordings we have created here https://www.edx.org/course/c-programming-getting-started it includes a client side c interpreter . If you know any other tool to make pedagogical tutorials please let me know!

Storytime [0] is a new screen-sharing product that we're adding on top of our core offering, which is an open source live chat tool [1]. Our long term goal is to provide an open source alternative to Intercom, but this is something that a lot of our users have been asking for in the meantime :) Storytime is built on top of the amazing rrweb [2] library, which captures snapshots of DOM mutations and streams them over a secure Phoenix channel (websocket over wss) [3] to a page in our dashboard. It doesn't persist any of this data, and the streaming only starts when you trigger it (so your website isn't constantly streaming these events through a websocket unnecessarily). And since we're open source, if you're concerned about privacy, you can always just host it on premise :) Would love any feedback! [0] https://github.com/papercups-io/story

This looks like it uses rrweb which is open source and can be self hosted. https://www.rrweb.io/ https://github.com/rrweb-io/rrweb Nonetheless nice work and it's good to see alternatives emerge.
