  • High-concurrency query support (hundreds of thousands QPS) requires significant cluster infrastructure investment

  • Free plan limited to 1,000 blocks for 2+ member workspaces, restricting team usage
  • Free tier only includes trial AI capabilities; full Notion AI requires paid plan
  • Page history limited to 7 days on free plan
  • Per-member pricing increases costs for teams compared to flat-rate competitors
  • Limited automation capabilities compared to dedicated workflow platforms
