FAQ

Questions we've answered a thousand times.

Is video really E2E encrypted?

Yes. WebRTC SRTP with custom DTLS-SRTP keys negotiated per peer. Sierra cannot decrypt the streams in transit.

How big is the conference?

1,000 active participants in live mode, 10,000 in the broadcast / town-hall mode.

Can it replace Slack?

Yes — same chat semantics (channels, threads, search) with voice, video and conferencing rolled in.
