Where each one falls short

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

LINE WORKS

  • The external LINE bridge, which is the main reason to choose it, only matters where LINE has consumer penetration, so buyers outside Japan, Taiwan and Thailand are paying for a feature they cannot use.
  • The free tier caps total storage at 5GB across the whole organisation, not per user, so a team sharing photos or documents exhausts it within weeks and is pushed onto a paid plan.
  • Business email is only on the Advanced plan at 800 yen per user, so an organisation wanting both chat and mail pays nearly double the Standard rate for every seat including staff who only chat.
  • Developer documentation, support and the integration catalogue are strongest in Japanese, which makes it awkward to administer from a non-Japanese IT function.
  • It has no serious developer or engineering workflow story, so organisations that also run Slack or Teams for technical teams end up maintaining two chat systems and two directories.

WhatsApp

  • Consumer app messaging and calling is free, but the vendor notes carrier data charges may apply
