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.
Messenger
- While message content is end-to-end encrypted by default since December 2023, metadata such as who messaged whom and when is not encrypted and remains visible to Meta.
- Full functionality generally assumes a linked Facebook account, which ties messaging to a broader social profile many users would rather keep separate.
- Cloud chat backups, if enabled, are protected by a PIN the user sets, and losing that PIN without a recovery key can mean losing access to backed-up chat history.
- As a Meta product, its business model depends on the surrounding Meta advertising ecosystem, and account-level data outside message content still feeds that system.
- Group chat and calling features have historically launched later or with more limitations on Messenger than on some competing apps built encryption-first from the start.

Answered from the vendors’ own 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.
Messenger: Is Messenger encrypted by default now?
Yes, since December 2023 personal chats and calls are end-to-end encrypted by default, moving on from the earlier opt-in Secret Conversations mode.
LINE WORKS: Is there a free plan?
Yes, up to 30 users with 5GB of total organisation storage.
Messenger: What can Meta still see if chats are encrypted?
Metadata such as who is messaging whom, when, and group membership is not encrypted and remains visible to Meta, even though message content is.
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.
Messenger: Do I need a Facebook account to use Messenger?
In some markets Messenger can be used with just a phone number, but most features assume a linked Facebook account.
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.
