The short version

  • Each has a real cost: Lark vendor website positions as best-priced but actual costs not verified; Viber viber has limited relevance outside its strong regions, so building a communication strategy around it in North America or most of Western Europe reaches almost nobody.
  • They diverge on capability: Lark covers Team messaging, Viber covers End to end encryption.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Lark

  • Vendor website positions as best-priced but actual costs not verified

Viber

  • Viber has limited relevance outside its strong regions, so building a communication strategy around it in North America or most of Western Europe reaches almost nobody.
  • Ownership by Rakuten ties the app to a commerce and points ecosystem, and account data can be linked to Rakuten services in markets where that integration is active.
  • Business Messages pricing is metered per message, so a company sending high volumes of promotional content can find costs rise quickly compared with a flat fee model.
  • Viber has lost share even in some of its historically strong markets to Telegram and WhatsApp, so its regional dominance is not guaranteed to persist.
  • The desktop client depends on the phone app remaining active and connected, which is a limitation for anyone wanting a fully independent desktop messenger.
