Best for	Regulated enterprises and government teams that must run chat on their own or air-gapped infrastructure.	Government and defense organizations that need federated, self-hosted chat with data kept on their own infrastructure.	Teams of 10-5,000+ that run on many connected apps and need the largest integration ecosystem, though the free plan keeps only 90 days of history.	Distributed teams and open-source communities that work asynchronously and want every conversation threaded by topic.	Teams of 5-50 that want Slack-style chat with unlimited history at a few dollars per seat, though the free plan caps integrations at three apps.	Remote teams of 5-50 across time zones that prefer threaded async discussion over real-time chat, though it has no built-in calls and the free plan keeps one month of history.
