FAQ
Is Slack's free plan still usable?
Barely. The 90-day message history limit means you lose context on older conversations. For teams that reference past discussions, this is a dealbreaker. Discord and Teams both offer unlimited history for free.
What's the best Slack alternative for remote teams?
Twist ($6/user/month) is purpose-built for async remote work — threaded conversations reduce notification fatigue. For teams wanting video-first, Microsoft Teams is excellent.
Can I migrate from Slack?
Most alternatives offer Slack import tools. Twist, Rocket.Chat, and Microsoft Teams all support Slack data imports. Your messages and files can usually be transferred.
