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; KakaoTalk kakaoTalk has minimal relevance outside South Korea, so it is the wrong tool for reaching audiences anywhere else.
  • They diverge on capability: Flock covers Team chat, KakaoTalk covers Plus Friend business accounts.

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

KakaoTalk

  • KakaoTalk has minimal relevance outside South Korea, so it is the wrong tool for reaching audiences anywhere else.
  • Standard chats are not end to end encrypted by default; a Secret Chat mode with encryption exists but must be turned on per conversation.
  • Concentration of messaging, payments, banking and mobility data inside one company creates a single point of both convenience and risk that has drawn scrutiny from Korean regulators.
  • Plus Friend business messaging costs scale with volume, so a company messaging its full Korean customer base regularly can face a meaningful recurring bill.
  • A 2022 data centre fire caused a multi-day outage across KakaoTalk and related Kakao services, which showed how much everyday activity in Korea depends on a single provider staying online.
