The short version

  • Each has a real cost: Lark vendor website positions as best-priced but actual costs not verified; 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.
  • They diverge on capability: Lark covers Team messaging, LINE WORKS covers External LINE 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.

Lark

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

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.

Answered from the vendors’ own pages

Lark: What pricing plans does Lark offer?

Lark advertises itself as a best-priced all-in-one solution with multiple pricing plans, but specific pricing tiers, costs, and features are not publicly detailed on accessible pages.

LINE WORKS: Can LINE WORKS really message ordinary LINE users?

Yes. That is its core differentiator and the reason Japanese customer-facing businesses buy it.

LINE WORKS: Is there a free plan?

Yes, up to 30 users with 5GB of total organisation storage.

LINE WORKS: Does the Standard plan include email?

No. Business email is Advanced only, at 800 yen per user per month on an annual contract.

LINE WORKS: Is it worth buying outside Japan?

Generally no. Without the consumer LINE bridge it competes poorly against Slack, Teams or Lark on features and ecosystem.
