The short version

  • Each has a real cost: Flock the Starter plan only makes the most recent 10,000 messages searchable and caps public channels at 10; 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.
  • They diverge on capability: Flock covers Team chat, Sessions covers Agenda blocks.
  • Prices and features above were last checked on 1 September 2026.

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 Flock
  • 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 Flock
  • A customer success team running onboarding sessions that must produce a consistent record of what was covered and what the customer asked.not Flock
  • 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 Flock

Where each one falls short

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

Flock

  • The Starter plan only makes the most recent 10,000 messages searchable and caps public channels at 10
  • Starter storage is 5 GB for the entire team, against 10 GB per member on Pro and 20 GB per member on Enterprise
  • Starter allows a single team admin and a single approved domain
  • Group video calls and screen sharing require the Pro plan; Starter is limited to 1-1 video calls
  • Group video calls are capped at 20 participants even on Enterprise
  • Single Sign-On and Active Directory sync are Enterprise only
  • Enterprise is quote only, with no published rate, and is positioned for organisations with 100 or more members
  • Unlimited auto-join and announcement channels require Enterprise; Starter and Pro get one of each

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.
