Chat without limits

Chat for your whole organization: channels, threads, and integrations.

Get started

# Channels and threads

Structure your discussions.

Set up channels for different topics, open or private. Keep every discussion in its own thread, instead of sprawling email chains.

# Unlimited history

Nothing disappears after 90 days.

Search your entire message history, with no time limit and no plan-based restrictions.

# Fixed pricing

Don't pay per account.

Pay one flat price for your organization, not per-user licensing fees.
