Quiet (https://www.tryquiet.org) is an alternative to team chat apps like Slack, Discord, and Element that does not require trusting a central server or running one’s own. In Quiet, all data syncs directly between a team’s devices over Tor with no server required.
NOTE: Quiet is not audited and should not be used when privacy and security are critical. It lacks basic features and probably won’t replace your Slack or Discord yet. That said, it works surprisingly well and we use it daily as a Slack replacement.
Quiet is for fans of software freedom, decentralization and privacy tech, and for anyone craving a future where humanity can collaborate effectively online without trusting our communities, networks, and data to giant corporations.
