โดย ToolVS Research Team · อัพเดทล่าสุด เมษายน 2026
The best Slack alternative for most people is Microsoft Teams because it is included free with Microsoft 365 subscriptions, ให้บริการ ไม่จำกัด message history, and รวม built-in video conferencing and file collaboration.
ทำไมผู้คนถึงย้าย from Slack
1. ราคา adds up for large teams. Slack Pro มีค่าใช้จ่าย $8.75/user/เดือน. A 100-person company pays $875/เดือน just for chat. Microsoft Teams is often already included in their Microsoft 365 subscription.
2. 90-day message history limit on free plan. Slack free plan now only shows 90 days of messages. Teams lose access to older conversations, files, and context. Discord and Teams offer ไม่จำกัด history for free.
3. Tool consolidation. Many companies already pay for Microsoft 365 or Google Workspace, both of which include team chat. Paying for Slack on top feels redundant.
