We don't infer weaknesses from missing or differently worded vendor marketing copy. Use documented plan limits, migration requirements, and other sourced constraints as decision inputs; anything not supported by a source remains unverified.

- Bring-your-own and multi-LLM support in the agentic platform
- Enterprise access controls, compliance, high availability, and secure mobility on higher tiers
- Mattermost does not publish stable numeric prices for Professional, Enterprise, or Enterprise Advanced; buyers need a quote.
- Paid self-hosted Professional and Enterprise licenses are prepaid annual seat subscriptions, so the commitment is different from month-to-month SaaS chat.
- Running Team Edition or another self-hosted deployment means your organization owns infrastructure, upgrades, backups, monitoring, and operational security.
