Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Mattermost.

  • No published pricing on public website; requires sales contact for all tiers
  • Three tiers (Professional, Enterprise, Enterprise Advanced) have feature differences but no cost transparency
  • User scaling caps differ between tiers without public price justification
