Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Flock
- The Starter plan only makes the most recent 10,000 messages searchable and caps public channels at 10
- Starter storage is 5 GB for the entire team, against 10 GB per member on Pro and 20 GB per member on Enterprise
- Starter allows a single team admin and a single approved domain
- Group video calls and screen sharing require the Pro plan; Starter is limited to 1-1 video calls
- Group video calls are capped at 20 participants even on Enterprise
- Single Sign-On and Active Directory sync are Enterprise only
- Enterprise is quote only, with no published rate, and is positioned for organisations with 100 or more members
- Unlimited auto-join and announcement channels require Enterprise; Starter and Pro get one of each
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.
