Super good for expensive running shoes - they’re always going on sale but you don’t know when.

Super cool to see a real use-case of WASM outside of just game dev and nerding out.

Thanks - super interesting to hear about your past experience, and indeed there are a bunch of privacy-preserving features on our roadmap!

Thanks and yes - there's an aux input, and many of users do exactly what you outlined!

Thanks and totally agree - especially since we're trying to enable frictionless communication, we knew we had to minimize latency from the get-go.

We use the standard WebRTC model where 1:1 Sidekicks are peer-to-peer (video streams sent directly to other clients), and 3+ Sidekicks go through SFUs that we host on AWS. These SFUs deployed all around in the world (in every major AWS region), and we assign Sidekicks to the SFU nearest to everyone on their team.

Internally the metric we aim for is to keep the end-to-end latency under 200ms.
