Team chat · 2026
The 4 best
Slack alternatives
Per-seat pricing and the 90-day message limit on the free plan push small teams to look elsewhere.
Reviewed by Switchpoint Editors ·
Our take
If you're a startup under 25 seats, Slack is worth the money. Past that, do the math: Mattermost self-hosted breaks even around 100 seats; Discord works for communities and dev teams that don't need enterprise compliance; Zulip's threading model genuinely beats Slack's for async work. The decision is rarely about features — it's about which trade-off your team will actually tolerate.
Switching cost
Slack exports JSON cleanly on paid plans, but most competitors can't replay the threading. Plan a 2-week parallel-run, not a hard cutover. The real cost is breaking integrations — every Zap, every bot, every approval flow.
