The short version

  • Only Sessions has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mattermost no published pricing on public website; requires sales contact for all tiers; Sessions it will not replace Microsoft Teams or Google Meet for everyday internal calls, so most buyers end up paying for two conferencing tools and asking staff to know which one to open.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Mattermost

  • Team messaging and collaborationnot Sessions
  • Secure enterprise communicationnot Sessions
  • On-premise or self-hosted deploymentnot Sessions

Sessions

  • A sales team running the same product demo dozens of times a month that wants the agenda, the deck, the poll and the follow-up questions to be one reusable object rather than rebuilt each time.not Mattermost
  • A trainer delivering a recurring workshop where breakouts, exercises and materials need to run in a fixed order without the host juggling tabs live.not Mattermost
  • A customer success team running onboarding sessions that must produce a consistent record of what was covered and what the customer asked.not Mattermost
  • A small company running public webinars that needs registration, reminders, attendance data and a recording without buying a separate webinar platform alongside its meeting tool.not Mattermost

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

Sessions

  • It will not replace Microsoft Teams or Google Meet for everyday internal calls, so most buyers end up paying for two conferencing tools and asking staff to know which one to open.
  • The vendor is small and European, competing directly against Zoom and Microsoft, so any team standardising a customer-facing process on it should keep an exit plan and export recordings regularly.
  • The preparation model that makes it good is also overhead; a meeting nobody had time to structure runs no better in Sessions than anywhere else, and teams that will not prepare get no benefit from the licence.
  • Lifetime deals sold through AppSumo mean a segment of the user base pays nothing recurring, which shapes support priorities and has previously produced friction when plan terms changed.
  • It is browser-only, which keeps participation frictionless but leaves it more exposed to browser and network conditions than a native client, and there is no desktop application to fall back on when a call misbehaves.
