Where each one falls short

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

Slack

  • 90-day message history limit on free plan results in important conversations disappearing
  • Per-user pricing becomes expensive quickly for larger teams
  • Notification overload with 78% of employees feeling overwhelmed by notifications
  • Mobile app performance issues including lag and slow syncing
  • Huddles limited to 50 people and cannot be recorded
  • Requires dedicated video conferencing service for formal meetings and webinars

WeChat

  • Chat content, payments and mini program activity are subject to Chinese content moderation and data law, and accounts can be restricted or suspended for content that would be unremarkable elsewhere.
  • There is no meaningful end to end encryption on standard chat, so message content is not private from the platform in the way Signal or WhatsApp users might expect.
  • The international version has a materially reduced feature set compared to the domestic app, so overseas users cannot access the full payments and mini program ecosystem.
  • Real name registration is effectively required to use WeChat Pay, which ties financial activity to a verified identity.
  • Switching away is costly for anyone embedded in Chinese business or family networks, because contacts, payment history and mini program relationships do not transfer to another platform.
