# Zulip (https://devrel.directory/directory/zulip)

Open-source threaded team chat; the community home of Rust and other projects that outgrew unthreaded chat.

Every message lives under a topic within a channel, so conversations stay followable asynchronously and remain searchable years later; public archives can be exposed to the open web. Self-host the open-source server or use the cloud, which is free for open-source projects. Chosen by communities that treat chat history as documentation rather than scrollback.
