Best Slack Alternatives in 2026
These are the 5 closest tools to Slack that we track, ordered by what they cost to start. Each entry says how its pricing differs from Slack's — based on the numbers we hold, not on who pays us. We do not publish a quality score, because we do not have one we can stand behind. The cheapest verified option is Microsoft Teams at $6/user/mo.
Why people leave Slack
- Notification Fatigue: Can be highly distracting if not properly configured by the user.
- Free Plan Limits: Access to message history is restricted on the free tier.
- Enterprise Pricing: Per-user licensing costs can add up quickly for large organizations.
These are the drawbacks listed in our own Slack review — not complaints we invented for this page.
