The short version

  • Only Naver Works 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; Naver Works the integration ecosystem is small by comparison with Slack or Microsoft Teams, so any workflow that depends on a long tail of third-party apps will need custom development against the Works API.
  • Prices and features above were last checked on 31 August 2026.

  • Secure enterprise communicationnot Naver Works
  • On-premise or self-hosted deploymentnot Naver Works

Naver Works

  • A Japanese retailer whose customer service happens over LINE and needs those conversations inside an auditable corporate systemnot Mattermost
  • A Korean company that needs electronic approval workflows in the local style rather than a generic chat tool with a form bolted onnot Mattermost
  • The Seoul or Tokyo office of a multinational that needs a local-language collaboration tool alongside head office Microsoft 365not 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

Naver Works

  • The integration ecosystem is small by comparison with Slack or Microsoft Teams, so any workflow that depends on a long tail of third-party apps will need custom development against the Works API.
  • Documentation, support and most community knowledge are in Korean and Japanese; an English-speaking administrator will spend a lot of time in machine translation.
  • Pricing is published in Korean won and the buying experience assumes a Korean or Japanese business entity, which complicates procurement for a company incorporated elsewhere.
  • The Lite tier omits business email, so the plan that looks cheap is messaging only and the realistic entry point for most companies is Standard at more than double the price.
  • Clova Note transcription and several AI features are sold as separate line items rather than bundled, so the quoted per-user figure understates what a team using the full suite actually pays.
