Why Teams Switch

Why Switch from Slack?

💰

Escape Per-Seat Pricing

Slack's per-user pricing makes costs spiral as you grow. OpenChat offers flat-rate plans that stay predictable at any scale.

🏠

Own Your Data

Self-host OpenChat on your infrastructure for complete data control. Meet compliance requirements that cloud-only Slack can't satisfy.

🔒

Enterprise Features Included

SSO, audit logs, and compliance features are included in all plans. Slack locks these behind expensive Enterprise Grid.

📜

Unlimited Message History

Full searchable history on all plans. Slack's free plan limits you to 90 days, forcing upgrades for history access.
