About Zulip

Zulip is a team chat app built around organized conversations. Its site describes it as organized team chat for distributed teams, with desktop and mobile apps, integrations, and an API.

Zulip's software is 100 percent open source according to its plans page, and the repository is licensed under Apache-2.0.
