The bottom line

Discord is the value play — it's free for most use cases, has excellent voice chat, and doesn't limit message history. For startups, developer communities, and small teams, it's genuinely a great Slack alternative.

But Discord wasn't built for business. It lacks enterprise compliance, admin controls, and the professional integrations that growing companies need. The interface also reads as "casual" — which may or may not matter for your team culture.

If you're pre-Series A or running a community, Discord is hard to beat. If you're scaling a company and need audit trails, SSO, and data retention policies, Slack is the mature choice.
