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; Kakao Work the product, documentation, support and commercial materials are Korea-first, so a company with overseas offices ends up running a second messaging tool for non-Korean staff and splitting its conversation history across two systems.
  • They diverge on capability: Flock covers Team chat, Kakao Work covers KakaoTalk-style messaging.
  • Prices and features above were last checked on 31 August 2026.

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

Kakao Work

  • The product, documentation, support and commercial materials are Korea-first, so a company with overseas offices ends up running a second messaging tool for non-Korean staff and splitting its conversation history across two systems.
  • The third-party integration catalogue is small next to Slack or Microsoft Teams, so connecting a Western SaaS stack usually means writing against the open API yourself rather than installing an app.
  • Prices are set and billed in Korean won with 10 percent VAT added on top, which makes cost forecasting awkward for any buyer whose budget is held in another currency.
  • Kakao Enterprise has restructured repeatedly since 2023 and refocused around AI, which puts long-term roadmap certainty for the collaboration suite below that of a vendor whose only product this is.
  • The deliberate resemblance to consumer KakaoTalk is a training advantage but a governance risk: staff move between the two apps by habit and a share of work conversation keeps leaking back to personal accounts, which is precisely what the tool was bought to stop.
